A house without a foundation: how to build a wooden and frame type with your own hands

Many of us have long dreamed of building a country house on our own plot of land. The fact that such houses are usually needed for one season makes it possible to install lightweight buildings and save on foundation construction. However, to underestimate this stage of construction work would be a big mistake, which could subsequently result in the destruction of your country house.

Roof installation options

The same materials are used for the roof truss system as for the frame.
The sheathing is made from inch boards. You need to make sure that there is no wane, otherwise the tree will quickly rot. Most often, the barn is covered:

A pitched roof, where the slope is supported on opposite walls of different heights. Suitable for span widths up to 6 m.

Gable, in which the walls are the same in height, and the slopes meet at the highest point - the ridge. Span width from 6 m.

The angle of inclination of the roof depends on the intensity of wind and snow loads:

the stronger the wind in the region, the smaller the angle of inclination should be;
for snow loads the relationship is the opposite - to quickly melt away a large mass of snow, the slope needs to be made larger.

In addition to the loads, the recommendations of the roofing material manufacturer are taken into account, determining the angle of inclination and pitch of the sheathing for a particular type.

Shed with pitched roof

As a rule, the span in barns is small, so a lean-to structure is the most rational. When installing the frame, you need to ensure the minimum permissible angle of inclination for the purchased roofing material:

slate 20-35°; soft roof 5°; corrugated sheet 8°; piece material, metal tiles 25°.

To support the rafters in buildings made of blocks, a support beam - a mauerlat - is installed on opposite walls. In frame buildings, the role of the mauerlat is played by the timber of the upper frame.

Starting from opposite walls, lay rafter boards on edge. The pitch depends on the cross-section of the lumber and its length. To increase the load-bearing capacity, the elements are connected in pairs. They are secured to the support beam with a tie-in and metal plates.

If insulation is not intended, steam and waterproofing is not used, since its function is to protect the insulation from condensation coming from the lower surface of the roofing sheet. Lathing from inch boards is laid along the rafters in increments of 30-50 cm (follow the manufacturer’s recommendations). They are nailed to the rafters or screwed with self-tapping screws.

The last stage of building a lean-to shed with your own hands is the installation of roofing material:

Slate is fastened with nails in the upper wave, metal tiles - with roofing screws in the lower one.
To seal the joints, EPDM rubber gaskets are used.
The sheets are laid with longitudinal and transverse overlap.
The minimum roof overhang for thin sheet materials is 100 mm, for slate 50 mm.

Barn with gable roof

Installation of a rafter system of 2 slopes involves the installation of a ridge unit. It is performed in various ways:

with an overlay at the apex of the corner;

with escutcheon and spacer bolt;

with the rafters resting on the ridge girder;

adjacent to the ridge beam.

The roofing materials in the ridge are not joined tightly. The gap is necessary for air circulation in the under-roof space. To prevent precipitation from penetrating into the gap, metal ridge elements are installed.

A gable roof is more difficult to install, but it resists wind loads better. Another plus is the ability to use the space under the roof for various needs.

Columnar foundation for light outbuildings

When building any foundation, the weight of the building must be taken into account. Lightweight outbuildings do not require a monumental foundation, so columnar foundations are most widely used for them. Their choice is due to the following qualities:

speed of installation;
low cost;
ability to provide reliable support.

The columnar foundation is installed on a cushion of sand or fine gravel; in the upper part, the pillars are connected by beams, on which the base will be installed in the future. It is important to take into account the depth of soil freezing and the degree of heaving. This type of foundation is suitable for low-moving soil, otherwise the structure may shift.

Making the roof of a frame house with your own hands

The roof of a frame house consists of rafters, which are made from 5×15 timber. The edges of the beams are joined using an end connection at an angle of 50-55 degrees and nailed together. The structure is reinforced with a horizontal board and resembles the letter “A”. The rafters can be assembled on the ground and then secured to the frame using miters and 200mm nails.

Sheathing boards are attached to the rafters every 10 cm. The boards should extend beyond the outer rafters by 20-25 cm. Roofing felt is spread onto the sheathing, after which roofing material, metal tiles or ordinary slate are screwed on.

How to register your own country house in 2020 - step-by-step instructions

The second step is paying the state fee. Payment details will be provided directly by the authorized body - a branch of Rosreestr or the MFC. Here you can find out what documents are needed to carry out the operation of registering country houses, garages, outbuildings and other buildings located on the garden plot.

they were not recognized as unauthorized construction and were not demolished legally;
to avoid disagreements with neighbors regarding the location of residential and commercial buildings, as well as to eliminate disputes about the boundaries of land plots;
receive compensation in case of damage caused by third parties or in case of demolition of buildings for municipal or state needs;
eliminate the possibility of the Federal Tax Service charging property tax for 3 years and a fine, the amount of which is 20 percent of the amount of this tax;
eliminate the possibility of problems when connecting gas, electricity and other utilities;
gain the opportunity to make transactions with this property, as with any other property: donate, sell, inherit, insure, use as collateral for lending.

Advantages of frame houses

Today's building materials and techniques are gradually pushing traditional construction methods into the background. Northern Europe has been building houses using frame technology for a long time. Now many Russian developers are doing the same. What's so good about these houses?

The base of a one- or two-story building will be a wooden or metal frame. But we prefer the first. Walls are attached to it. On the walls - floors and roofing. The resulting structure is monolithic and reliable. Then comes insulation, finishing work and the house is ready. Let's look at the advantages of frame houses:

Low cost. Currently, this is the most affordable method of building houses.
High speed. On average, a team of qualified workers of 3 people will build a two-story house in 2–3 months.
Low operating costs. The building is considered multi-layered, so it is warm in winter and cool in summer. In addition to creating a comfortable living environment, you save on heating and cooling costs.
Low heat capacity of enclosing structures. If you leave the house for a long time, you can quickly warm it up to the desired temperature.
Lightweight foundation. The frame itself and the walls are not so heavy, so you don’t need a powerful foundation for them. You save a lot of money and reduce construction time. As a result, you get a monolithic frame building.
No shrinkage. Construction of houses using this method makes it possible, after installing the parts, to immediately begin finishing work.
Lack of technology. House assembly does not involve heavy structures, so lifting mechanisms are not needed.
Quick dismantling and installation of the same elements in a new location.
All communications can be easily hidden in the walls, as can be seen in the video.

Unfortunately, we have not yet come up with such a building material or method that would be ideal. If there are advantages, then there will definitely be disadvantages:

The hollowness of wooden structures. The small mass of the structure does not sufficiently dampen significant vibrations.
A properly designed project and appropriate tools are required.

Application of frame technology

It is worth noting that buildings can be erected without a foundation if they have a low enough mass. A good example is a house assembled using frame technology. Judging by statistics, around the world about 70% of all residential buildings are built using this technology. The structure is assembled from a frame, the inside is filled with insulating material, for this reason the whole house is very light and does not create a high load on the ground.

It is also worth noting that relatively recently Japanese scientists have developed completely new house designs, which differ from frame technology in their simplicity. Houses are built in literally a couple of hours, since the main material is polystyrene foam. Dome structures are erected in two to three hours, then all joints are carefully sealed, and external and internal finishing is carried out. Therefore, it seems that the house is built from stronger materials.

But this is relevant for Japan, where there is a high seismic hazard. After all, such structures are able to withstand strong vibrations of the earth's surface. But in our article we will look at how to build a frame house without a foundation. We will not consider how to fill the strip and pile.

Preparation and marking of the site for the construction of a frame house with your own hands

Preparing and marking the site is one of the most important actions during construction, so this should be approached with all responsibility. The first step is to clear the area of various debris, remove snags, stumps, demolish old structures that are not necessary or if they will interfere with construction. Next, we provide free delivery of building materials. It is also worth considering where to turn the vehicle if it is not possible for it to reverse. It is better to equip places for future storage of building materials with a canopy.

If necessary, the area must be leveled. A good-quality fence will not hurt, it will ensure the safety of materials and prevent their theft. Often, before starting construction work, owners install a module or trailer in which they themselves live during construction.

The better the site is prepared, the easier construction will be.

The marking begins with the fact that, according to the diagram, the outline of the future house and the internal walls are transferred to the area, marked with pegs with ropes. Angles must be measured carefully. If the angle deviates even a few degrees from the required 90°, the loads will be distributed incorrectly. This will lead to curvature of the walls and fragility of the structure.

Remember that the more carefully the preparation and marking are done, the easier it will be to carry out the work. By the way, the quality of the final version directly depends on this. As for the project, for frame houses it is allowed to carry it out by hand, in the form of a sketch. It can be provided to the administration after the frame house is completed on a turnkey basis, before it is put into operation. However, it is necessary to have an approximate project for yourself with communications marked on it.

A frame house project can also be done on a computer using 3D modeling

Building on boulders

When building houses in mountainous areas or in areas where rocky soil predominates, it is very difficult to build a simple foundation. Therefore, boulders (stones) are used instead. Houses that are installed on such stones have very high stability. A stone foundation has all the advantages of a conventional foundation. In addition, there is almost no financial investment in the construction of such a foundation.

During construction, it is necessary to place large stones in the corners of the future structure. It is also necessary to install several along the long walls of the structure. Along the perimeter of the building it is necessary to arrange a rubble with openings for ventilation. It is made of wood, after which it needs to be covered with soil. Houses made using this technology can last for many years. It is worth noting the fact that the lower floor practically does not rot and will not lose its strength even after several decades.

Construction of walls of a frame house

Before installing walls, you need to carefully inspect the base; it must be perfectly level. If there are unevenness on the base, this will negatively affect the structure of the house as a whole, and distortions may appear.

When building a house using Canadian technology, it is best to use SIP panels for the construction of walls. Their installation is not very difficult and does not require much time, and the finished house will be warm.

So, first you need to complete the bottom trim; then SIP panels will be installed on it. The piping must be carried out in full accordance with the drawings of the future housing. The fixing of the trim boards is carried out throughout the house and around the perimeter so that they fully comply with the existing wall structure

It is very important that the width of the boards allows the panel to fit freely into it, because the construction of walls is carried out using the tongue-and-groove method. Now you will need to securely fix the strapping to the base; for this it is recommended to use self-tapping screws, but in order to place it correctly, they usually use a template made from trimmed SIP panels. To ensure a higher level of reliability, you will need to make a small hole in the base all the way to the foundation and secure everything

Anchor bolts are used for fastening. Experts advise installing walls starting from the corners of the house. It is necessary to install the first SIP panel according to the level and fix it to the beam using self-tapping screws and foam. The junction is foamed and the next panel is mounted so that it forms a corner of the house. At the corner, the sip panels are connected to each other using self-tapping screws two hundred and twenty millimeters long. Next, following the drawings, we build the structure in the same way as we previously installed the floor in the house.

To fix the slabs one to another, use a beam, this will be a tenon. The tenon is inserted into the groove of the plate. As soon as the frame is made, you need to foam the grooves of the panels with foam and then carefully insert the strapping board into them. The next step is to create the overlap. Simple boards can be used to construct it.

If you plan to build a wooden house on two floors, then after installing the floor, the construction of the walls is carried out in exactly the same way as the construction of the walls of the first floor.

Main features of frame structures

It is worth noting one important feature of buildings that are assembled using frame technologies. When designing, it is extremely important to provide for additional structural reinforcements. It is quite possible that heaving soil will affect the house, this is especially true when there are high temperature changes.

But despite this, strengthening the frame of the house will cost you much less than building even the cheapest foundation. Now let's look at alternatives for foundations that are actively used in the construction of houses and other structures.

Spacer for openings

Depending on the type of timber or log, a do-it-yourself wooden house shrinks by 6–9% on average; house made of laminated veneer lumber – up to 3%. This must be taken into account when planning to install windows and doors. To avoid skewing and cracking of frames and door frames, it is worth installing frames on window and door openings after construction is completed.

They are T-shaped plates. The brackets are installed as follows:

1. Grooves are cut out at the ends of the adjacent crowns.
2. Wooden blocks are hammered into them.
3. Stuff the pigtails on top along the entire perimeter of the openings.
4. The gaps between the pigtails and the ends of the crowns are filled with tow.

In the future, the walls must be given time to “fall” into place. During this time, the openings maintain a rectangular or quadrangular shape and do not warp, since the ostriches hold them securely. When the main shrinkage is complete, window frames and door frames can be mounted on top of the frames.

Experienced carpenters know how to install frames on window and door openings of complex configurations. And it’s better to entrust even simple work to them. With minimal experience, cracking of the crown often occurs at the end, breaking of the frames during shrinkage of the crowns.

So, you now know how to make a wooden house with your own hands. Happy construction to you.

Windows and doors for frame houses: types, pros and cons

For frame houses, 2 types of windows and doors are used - wooden or plastic (PVC). Of course, there is another material from which such products are made - aluminum. However, it has too high thermal conductivity, so it is used extremely rarely.

There is a lot of debate around the question of which windows are best to install. Some say that wood is more environmentally friendly, others say that PVC is more durable. And there are quite a lot of such “stumbling blocks”. Of course, everyone must decide for themselves, however, in the opinion of the Homius.ru editors, it is better to go with the PVC option, and now we will explain why. In our case, we are considering the independent construction of a frame house, and wooden windows and doors are quite difficult to install, compared to plastic ones. In addition, PVC is not susceptible to pests, which is very useful in the case of a wooden house.

Windows and doors of frame houses are installed before interior finishing begins.

Stage-by-stage construction of your building

Now let's talk in more detail about how to build a wooden shed without a foundation. With the most budget option, even pallet boards will be suitable for building a shed, you just need to clean them, remove all the nails and iron, and go over them with a plane.

So, let's start our construction:

We prepare the site - mark it out, remove debris and plants, compare the surface.
We use markings to guide the location of the shed.
At the corners we bury 4 bars, no less than 20 cm into the ground.
Fill them with cement and leave them to dry for a day.
During this time, we pour crushed stone onto the site to compact the soil.
Now we pour sand and level everything.
We begin to make a frame - we nail horizontal bars to the installed bars. We start from the bottom and end at the ceiling. The distance between them is half a meter. We do the same on the floor and ceiling. Fasten horizontal bars with vertical or self-tapping screws or nails.
Select one of the narrow sides and prepare an opening there for the door.
On an arbitrary wall we make an opening for a window.
We begin to sheathe the inside with boards or boards from pallets. We nail them down. We try not to leave any gaps. We cover everything except the floor.
When the interior lining is completed, go over it with a plane to remove all splinters and protect the livestock from injury.
It's time to lay the insulation. If you chose polyurethane, its sides are 50 cm long, and it is glued to the walls with mounting glue. You need to choose the one that interacts with the tree. Information about this is usually placed on the packaging. Insulation is placed everywhere except the floor.
The insulation is reinforced with waterproofing. If you have mats or membranes playing this role, then they are also glued with mounting adhesive. And if the material is self-adhesive, then remove the protective film from it and apply it to the insulation. We cover the walls and ceiling with waterproofing. It can also be attached using a mounting stapler.
Now it's the floor's turn. We put a waterproofing layer on the boards. Next comes 2 layers of insulation. Then they waterproof it again so that animal waste does not spoil the insulation.
We install the window and door according to the instructions included with them.
We cover the outside of the building.
We overlap the roof with corrugated sheeting, then water will not be able to flow under the roof. It will not be superfluous if you decide to lay a layer of waterproofing under the corrugated sheeting.
From the poles or from the wiring from the street we run wires for lighting into the barn. We install a socket and a switch on one of the walls. The socket is needed for the heating device in the winter.
All that remains is to make partitions from OSB and install them in their places. These slabs can be cut simply with a saw and secured to the floor and walls with nails.

Pros and cons of a non-buried strip base.

Advantages of non-buried tape:

Non-recessed belt type is an economical solution. Compared to the recessed type of base, it is 2 times cheaper.
The ability to create a foundation with your own hands thanks to a smaller scope of work.
A non-buried foundation allows you to make a small basement under the house; moreover, the heaving phenomena of the soil in this case are hardly noticeable.

This type is good only when laid on slightly intumescent soils and provided that the groundwater level is as low as possible. In other cases, it is better to use a pile foundation.
The strip can crack if it is erected on unstable or unevenly rising soil in winter.
On such a foundation it is possible to build only light houses. Two-story brick houses can only be built on non-heaving soil.

To make this look with your own hands, no special skills are required. The main thing is that the structure being built and the type of soil are suitable for this foundation.

Recommendation: This is just an overview article, from it you will learn the general concepts of a shallow foundation on a sand bed. In reality, in order not to lose your money and not seem like an unreasonable developer or builder in the eyes of other people, I recommend that you carefully make all the calculations specifically for your case, and only then make any decisions. Better yet, turn to professionals.

Using brickwork as a foundation

If you dare to build a small house without a foundation, you should carefully examine the soil. Many builders believe that there is no need to pour a foundation if the soil consists mostly of clay. There is also a second condition, which states that groundwater should be as far from the surface as possible.

If these conditions are met, then brickwork can be made from high-quality material. But keep in mind that at the base the masonry should have a thickness of about 1.4 m. At the level of the first floor, the thickness of the masonry can be approximately halved.

Building a base of stones with your own hands

If you can get a lot of rock fragments, you can save a lot of money on the construction of such a foundation.

A foundation made of boulders is not much inferior to a concrete monolith, so a wooden or frame house, bathhouse or outbuilding made of timber will last for many years.

To build a foundation from boulders with your own hands you will need:

Draw the outline of the foundation on the construction site,
Set aside the largest stones separately (they will be used to outline the base), and sort the remaining stones by size,
Dig a channel and place large boulders on its bottom. Place smaller stones on top of large boulders and fill them with cement mortar or compact them with sand and clay,
Place the beams that will be used for the structure’s frame on top of the largest stones.

Alternatives to foundation

The construction of buildings without a foundation is possible. The following materials can be used for this purpose:

Car tires;
boulders;
priming;
bricks;
foundation pit

Each solution has its advantages and disadvantages, but these materials can easily replace the foundation.

Car tires

The process of constructing a building on tires.
You can prepare the basis for the construction of a small building using car tires, on which the lower dressing beam is installed. This method is one of the cheapest and simplest. The service life of such a base is also at a high level.

To implement this method, tires are filled three-quarters with plain sand. During work, the sand must sometimes be moistened and re-compacted. After which the tires are completely covered with crushed stone. The result will be an excellent alternative to the foundation.

The tire base has the following advantages:

Excellent shock absorption characteristics. This parameter allows you to protect the building from periodic heaving of the soil.
The microclimate of the room is not disturbed.
The house stands quite firmly on such a basis. Many experts use this method, and no distortions of walls or openings for windows and doors are observed.
Low cost of this method.
Ease of arrangement and installation, which allows even beginners in the construction craft to use this method.

A base based on car tires will be the optimal solution for the construction of bathhouses or small utility buildings.

You can learn more about building a house on tires using the following video.

Buildings on boulders

In areas with rocky soil or mountainous terrain, boulders can be used as a replacement for the foundation. Buildings installed on such a basis are characterized by good stability.

A foundation made of stones has all the advantages of a classic foundation. At the same time, financial costs for materials are practically absent.

To erect a building, large stones will need to be installed in the corners of the planned building. Also, boulders should be installed along the long walls of the structure. A heap with holes for ventilation is created around the perimeter of the house. Its installation is carried out using boards, after which it is covered with soil.

Buildings on this basis have a long service life. The lower part of the room does not rot, and the house always remains strong.

House on the ground

You can build houses without a foundation with your own hands directly on the ground. But at the same time, there must be solid, non-flowing soil at the construction site.

To prepare the soil, you will need to remove a small top layer of soil. The entire area around the perimeter of the future building must be compacted, after which a layer of clay will need to be laid. This layer will help waterproof the building. The frame of the room is mounted directly on the clay.

Soil blocks are also used quite often. They were used in ancient times, but even today many builders use this technique. To make a soil block, you need to put the required amount of soil into a special container, and then compact it thoroughly. After removing the container, you must wait until the block is completely dry. From the prepared blocks a foundation is created around the perimeter of the house and a prefabricated structure is installed.

When using brick as a base, you need to consider the depth of its laying.

Brick foundation

To build a small house without a foundation, you need to carefully study the soil structure. Professionals have come to the conclusion that the foundation need not be poured if the soil at a depth of up to 2 m mainly consists of clay, and there is no groundwater near the construction site.

If all these factors are observed, it is possible to create masonry using high-quality bricks. Near the base, the thickness of the masonry should be more than 1400 mm; up to the level of the first floor, the thickness can be reduced to 700 mm.

Using a pit as a foundation

Arranging a pit
A rather unusual way to erect a building without a foundation is to use a pit. It must be dug to a depth of no more than 1 m. After which the hole is filled with stones and coarse gravel. Additionally, a mixture containing river sand is added.

On the upper section of the pit you will need to lay stones or bricks to a height of up to 200 mm from the soil surface and fill them with cement mixture. After which you can install the frame.

Buildings built on a foundation pit do not crack or shrink after quite a long time.

DIY frame house: step-by-step instructions with photos

In any case, it is more convenient to work when the lower level is ready. You don’t need to use ladders or stepladders every time you drive a nail, so after laying the bottom trim (bed), as a rule, the rough flooring or floors are installed. Lumber that will be located close to the ground must be impregnated with antiseptics to prevent rot.

Laying the bottom trim

Previously, the surface of the foundation is covered with cut-off waterproofing - a layer of hot bitumen and 2 rows of roofing material or waterproofing. This measure will prevent capillary moisture from leaking out of the concrete.

A beam with a section of 100x150 mm or 2 boards of 50x150 mm is used as the bottom trim. They must first be treated with antiseptics and the holes in the places where the studs will be installed must be prepared.

It is recommended to wall the studs in advance in the foundation, securing the lower end to the reinforcement frame. If this is not done immediately, you can screw anchor dowels with a thread for a nut into the hardened concrete. The length of the fastener is 150-200 mm, the diameter is 12-16 mm, the depth of immersion in the foundation is at least 100 mm. The installation step of studs or anchors is no more than 2400 mm.

Installing studs is a responsible operation. They must be strictly vertical, minimal deviations are allowed. Installation begins from the corners, then the mooring (cord) is pulled, and the rest of the anchors are attached to it. To avoid splashing the thread when concreting, paper, film or similar materials are wound onto it.

To mark the holes on the bottom trim, it is recommended to place a board or timber on top of the foundation directly on top of the studs and lightly hit the wood with a hammer. There will be fingerprints on the back side, which can be used for precise drilling. The harness must be positioned strictly horizontally and the nuts must be tightened.

In the corners, the beams are joined into a “foot” along the length with an oblique or straight lock with additional reinforcement with an overlay. When installing the strapping on a pile foundation, the connection must be located exactly above the support.

Installation of logs

Joists are horizontal purlins that serve as the basis for laying flooring, as well as lower sheathing and insulation. They are made from boards 50x150-80x220 mm, placed on edge, I-beams or composite beams. The section is selected based on the distance between the supports. The larger it is, the more powerful the beams should be.

The logs are attached in the following ways:

metal corners or brackets butted to the bed;

resting on the bottom trim, from the outside the ends are covered with a façade board.

The logs are joined only on the runs. They are nailed to the beam obliquely using nails, and screwed to the facade board with 2-3 self-tapping screws.

If the span is more than 2.5 m, spacers are installed between the beams to provide rigidity and prevent deflections. They are fastened with nails nailed obliquely to the joists.

Floor construction

A flooring made of boards, cement-bonded, particle-boarded or gypsum-fiber waterproof boards, and moisture-resistant plywood is laid on the finished base. The thickness is determined by the overlapped span:

400 mm - 30 mm GVL and 16 mm other materials;
500 mm - plywood, 16 mm chipboard, chipboard, 19 mm lumber, 36 mm gypsum fiber board;
600 mm - plywood 18 mm, DSP 26 mm, chipboard 19 mm, boards 36 mm.

In areas where the floor may become wet during use (bathrooms, bathrooms, kitchens, etc.), water-repellent treatment of the surface and edges of wood materials is carried out.

At this stage, insulation can be carried out, since the frame of the partitions is subsequently attached to the subfloor and dismantling the top covering will be difficult.

The following are used as thermal insulation:

backfill materials - expanded clay, vermiculite, perlite, etc.;
fibrous - basalt wool, glass wool, etc.;
polymer foam - extruded polystyrene foam, polystyrene foam, foam rubber;
sprayed - polyurethane, ecowool.

Skull blocks are nailed onto the logs at the bottom, and sheets of OSB and moisture-resistant plywood are attached to them. This is the basis for laying thermal insulation.

The further sequence depends on the type of material:

Mineral wool is the most capricious. It needs to be protected from the ingress of water and steam, therefore steam and waterproofing membranes are laid both below and above.
Expanded polystyrene is not afraid of moisture, but mice love it very much. In places where their penetration is possible, it is worth putting metal mesh with a fine mesh - 5-8 mm.

Backfill is more often used in floors on the ground. The backfill thickness is at least 20 cm. Sprayed types are applied with professional equipment. Quite a high pressure is created, so the lower casing must be very strong.

After laying the thermal insulation, the rough floor covering is installed. It serves as a horizontal base for the preparation of structures, as well as further installation of partitions.

What to look for when choosing

When deciding how to choose a foundation for a country house, it is important to be guided not by personal motives, but by objective construction conditions. The aesthetic component is certainly important, but the strength and safety of your home comes first.

Remember the important rule: “first geologists - then builders.” Soil indicators are always primary and determine not only the type of foundation, but also the architectural design of the future home. In addition, the choice of building materials and construction technology depends on geological indicators. Thus, weak, low load-bearing properties of the soil can force the customer to abandon the original idea of building a brick building and choose a frame building with brick cladding. There are areas where you can’t build anything at all except temporary shelters.

To find out what the objective indicators are on the site, they invite specialists who conduct professional geological surveys. However, every owner of a summer cottage must know basic information about the soil conditions on the site.

Freezing depth

The degree of soil freezing directly depends on the climate and soil type. There is a special regulation with SNiP standards, which includes average statistical indicators for different areas. Thus, in the Moscow region the freezing depth is 1.6-1.7 m, in the Leningrad region - 1.5 m.

The foundation for a garden house or cottage is usually installed deeper than the freezing level of the soil - this is the only way to ensure the required stability.

Soil type

The best option for durable and strong construction is rocky or clastic soil. Such soil allows moisture to pass freely and does not deform in winter. On rocky rocks, you can install any foundation of your choice.

Clay soil and peat bogs retain a lot of moisture, freeze deeply in winter and swell, forming uneven surfaces. As a result, buildings are deformed, cracks appear in the walls - the house may simply fall apart a few years after construction.

For such soils, a slab, pile-screw or strip shallow foundation is chosen.

Frame-panel houses

The corresponding structures have a rigid frame that can withstand significant loads for decades.

The walls of a frame house of this type serve as shield fencing. They are made of OSB (oriented strand board). The advantages of using thematic boards are obvious:

Consistent and operational installation;
Possibility of detailed dismantling;
Suitable for filling gaps between the inner and outer skins with polystyrene foam for thermal insulation;
Low loads on the foundation and supporting frame.

In the finished structure, you can immediately carry out interior decoration, installation of doors and windows, because its frame and walls do not shrink.

Foundation for wooden houses made of logs

Buildings made of rounded logs and beams have less weight than brick or concrete, but exceed frame houses, so the best option for them would be a shallow strip or pile-grillage foundation.

The first option allows you to equip a basement, has sufficient resistance to loads and is relatively low cost. To ensure its durability, it is necessary to equip it with high-quality waterproofing and pour a thick sand cushion.

For a pile-grillage foundation, you need to dig holes to the level of soil freezing and connect them with isthmuses. Then concrete is poured into the pits and ditches and a concrete strip is obtained, from which pillars emerge, resting on the soil below the freezing level.

These types of foundations provide the opportunity to equip a reliable and durable foundation that can easily support the weight of a wooden house of one or two floors and will allow you to avoid unnecessary overpayment by equipping an unnecessarily expensive support designed for an impressive mass.

Non-buried foundation - features of its design.

Unburdened foundation. Scheme of the structure of a non-buried (shallow) foundation. At the moment, the most common and popular foundations are strip, columnar, columnar with reinforcement, and slab. Strip foundations can be found in the construction of large and small private houses, industrial and administrative facilities. It is also popular for another reason - you can do it yourself without using mechanized equipment.

The peculiarity of such a foundation is that it strictly follows the contours of all load-bearing walls, so the mass of the structure is evenly distributed over the entire area of the base. A non-buried foundation can be made from concrete or reinforced concrete blocks, rubble stone, or less often brickwork.

Review of technologies for constructing buildings without foundations

You won’t see any kind of buildings today. These can be multi-storey apartment buildings that fill the streets of cities, it can also be a small private house in an unusual architectural design, as well as other buildings and commercial buildings.

Types of buildings without a foundation

At the moment, it is possible to erect any building completely without any foundation, but this must be done in accordance with all construction rules. Nowadays the following types of buildings without a foundation are considered the most popular:

a house without a foundation can only be built on solid ground. The main thing is that the foundation is laid under all load-bearing walls and supporting structures of the building;
a bathhouse without a foundation is a very convenient way to construct this type of building, because such a structure becomes mobile and can freely move to any place;
a stove without a foundation, just like a bathhouse, is very convenient and easy to set up;
a garage without a foundation should be installed on moisture-proof ground, because the structure will be very bulky and heavy. In most cases, such structures are made entirely of iron;
a fireplace without a foundation is a fairly simple design that does not require any additional knowledge for construction;
a polycarbonate greenhouse without a foundation is a lightweight structure that can be either prefabricated or installed once;
a shed without a foundation is a type of outbuilding that does not require a foundation, because they often simply use the method of creating a concrete pad and nothing more;
fences without a foundation are a structure that must be placed 1/3 of the way into the ground, only in this case there will be no need for a foundation;

A structure without a foundation must be durable and meet building codes, otherwise the building will not last for a long period of time.

Foundation without formwork

In order to build the foundation, formwork is used. Formwork is a structure made of iron, plastic or wood, which is placed in order to give shape to the base. Then the formwork is in most cases dismantled. But today it is possible to build a foundation for a building without formwork.

A striking example would be a strip foundation without formwork. Experts say that if it is intended to lay a shallow foundation of a strip type, then the formwork can be neglected and the foundation can be poured into a soil trench. But for this it is necessary to take into account one point - for such a foundation there is absolutely no need to create a concrete pad for the foundation. Consequently, this type of work is also affordable in price.

Special types of foundation

A trench for a strip foundation in the picture. As mentioned earlier, today there is a huge variety of foundations for different types of buildings. But, in addition to the usual ones: strip, monolithic, reinforced concrete, pile, etc., there are a number of other foundations, foundations of the “without” type, that is, foundations that are carried out according to a special program:

foundation without reinforcement - such foundations are installed using crushed stone and an already poured concrete structure;
foundation without deepening - erected using formwork. The structure is placed at a sufficient distance from the ground. It is imperative that the entire line is sealed;
a foundation without a basement - it is built quite often and does not require the creation of a deeply buried trench;
foundation without concrete - this type of foundation is erected only when the structure is not heavy, i.e. no serious load will be placed on the base;
foundation without crushed stone - often placed on solid ground; crushed stone, of course, gives special strength, but its presence is not necessary;
a foundation without a cushion is often erected, a cushion is erected when a large load is placed on the foundation, otherwise it is not so necessary;
a foundation without a base, just like a foundation without a basement, is a structure that does not require additional material to create additional load-bearing surfaces;

How to build a house without a foundation?

Where to start to build a house without a foundation? First, you should understand that nothing can be built on loose soil. Therefore, it is necessary to compact the soil first, i.e. create a dense compressed layer. A foundation on a pile foundation requires that these elements be placed 1/3 into the ground. This is very important, because otherwise the house will be shaky. Read about the features of building a foundation for a bathhouse on this page

As for a wooden house without a foundation, such a structure is most often placed on iron structures and raised to a sufficient distance from the surface.

In such a structure, it is important that high-quality insulation of the floor in the room is done.

You can build a garage without a foundation from large elements - blocks and shells. It is first necessary to press the surface on which the building will stand. How to build a foundation for a garage, read on this page

How to build a bathhouse without a foundation?

The construction of a bathhouse without a foundation only requires that the room be based on a frame structure, i.e. For its construction, a frame of metal or wood is first constructed. Otherwise, even an inexperienced builder can build a bathhouse using the frame method; the main thing is to make the correct hydro- and thermal insulation of the building.

It goes without saying that erecting a building without a foundation significantly saves money, but before choosing this method of constructing a house, you need to think about the service life of the structure and what type it will be.

Building a house with your own hands

A small frame house is a prefabricated and lightweight structure. Therefore, anyone can build it independently without using a foundation. But let's look at detailed instructions that will allow you to build a house with your own hands:

First you need to decide what kind of foundation the building will have. It is recommended to place the house on a hill. And it is imperative to develop a drainage system that will remove precipitation from the house. All structural elements - floor, walls, can be made of the same material. For the construction of walls, you can use 150x25 mm edged boards. If you plan to make thin walls, keep in mind that they will not be able to retain heat in the room. Therefore, it is necessary to provide for insulation. The main part of the prefabricated structure is a lightweight wooden frame. It must be made of vertical and horizontal strapping; all voids must be filled with insulation having a low degree of thermal conductivity. The base platform of a frame structure is its floor. First you need to use an unedged board, as it is very cheap. With its help you make the so-called subfloor. The next stage is laying the transverse joists. The space between them also needs to be filled with insulation. After all the work has been completed, floorboards will be laid on these joists. This is exactly how the foundation of a house is built without a basement. It is necessary to lay roofing material below the timber, and treat all the wood with impregnations that prevent the absorption of moisture. Mark the exact location of the walls relative to the floor. Secure the beams with anchor bolts 2 meters apart. Use a level to correctly align the geometry of the entire structure. It is not allowed to skew the corners diagonally by more than 10 mm. Now you assemble the frame of the future wall. Assembly should be carried out on a flat and dry surface to prevent distortion. First you need to prepare the boards; they must be the same size. It is the size of these boards that will influence the height of the ceilings. As a rule, for private houses the height is approximately 2.75 m

Please note that you do not need to make ceilings less than 2.4 m. In this case, it will put pressure on you, as a result of which you will feel discomfort. If you decide to arrange a second floor or attic, you need to make slanted ceilings

In addition, you will have to install windows in the roof. They will be able to give the room a sufficient amount of light, as well as visually increase the space. The assembly of the frame can begin with the manufacture of vertical partitions. There should be a distance of 40-60 cm between the beams. The width between the boards should be selected based on what material will be used for the cladding. If siding is used, then it is necessary to maintain a distance between the boards of 20-30 cm. When using chipboard or pseudo-timber, the distance should be 35-60 cm. It is worth noting that the siding that is used for cladding buildings is durable and practical. During operation, there is no need to treat it with impregnations or varnishes, as is the case with wood.

To give the building a personalized appearance, you can clad it with various finishing materials that can be found on the market. When assembling walls, be sure to provide windows

Please note that they should occupy more than 18% of the wall area. Only in this case will you be able to ensure maximum comfort in your home.

It is recommended to use double glazing for windows.

It is advisable to cover all walls from the inside with plasterboard. This is a universal material that allows you to make walls even. Any coating can be applied to it. But all communications must be laid inside the walls. Therefore, first you carry out the work on laying communications, and then you can line the inner surfaces. And the last stage is laying the roofing material. To make the roof lighter, it can be made of tiles or ondulin.

Soil block base

Blocks made from soil have been used for construction for a very long time. Nowadays, many builders also often use a similar method. In order to make a block from soil, you first need to make a mold. A certain amount of soil is placed in it, which is compacted as much as possible. Many people wonder whether it is necessary to insulate the foundation of a house without a basement? Of course, it is necessary, since the cold will begin to enter the house through the weakest points.

After this, you need to remove the mold and let the block dry completely. To make the base you will need several blocks. They need to be laid along the entire perimeter of the future structure. And on top of these soil blocks you need to install a frame structure.

Basic functionality of the foundation.

Let's look at the main functions of a concrete floor:

ensures uniform pressure of the building on the ground;
ventilation of the basement;
reduces the likelihood of building destruction;
stabilizes ground movements (oscillations).

So, we see that a house without a foundation is still possible. What tasks do we face when choosing an alternative foundation replacement? One of the main things is to prevent the building from becoming distorted. Also, the load of the building on the ground must be uniform. An example of such a house without a foundation could be an extension, a gazebo, a change house or a country house.

Construction on the ground

If the soil is hard and not loose, the building can be placed directly on the ground. In order to prepare it, you will need to remove the top fertile layer of soil. Instead, you need to add a layer of clay. It will perform the function of a waterproofing material. The frame structure can be installed directly on the clay layer. That's all, there is nothing complicated in construction, you just need to secure the entire structure so that the house does not roll down during rains or bad weather. And, of course, you need to insulate a house without a foundation. Without this stage there is nowhere.

Bottom rail and floor

To protect the piping from moisture from below, roofing material or waterproofing is laid on the foundation. You can use bitumen mastic, but it will be more expensive than roll material. Sometimes materials are combined: once the foundation is covered with mastic, and waterproofing is laid on top.

The assembly of a frame house begins with strapping. For it, boards with a section of 15x5 cm or timber 15x15 cm are used. The boards are laid around the perimeter and aligned along the outer edge of the foundation. Holes for the studs are drilled in the required places. The second layer of boards is laid in such a way as to cover the bottom joints of the boards. This gives the structure additional strength. Installation of timber is easier and faster, but its price is higher than that of boards. In addition, the overall load-bearing capacity of a double board will be higher than that of a single beam.

This is what fixed logs look likeSource goroddomov.ru

A 20x5 cm board is installed on the edge on the harness. It is also aligned along the outer edge of the foundation and secured with self-tapping screws. The logs are mounted from boards of the same section. Fastened with self-tapping screws or special corners. Installation step – 30–60 cm.

The next stage is insulation

It is important to choose high-quality insulation here.

Joints with joists must be sealed with sealing materials Source 9dach.ru

To install the subfloor, a 10x2.5 cm edged board is used. Plywood 0.5–0.6 cm thick is laid on top of it. Sheets of plywood can be laid immediately without a flooring of boards. In this case, the thickness of the sheets should be at least 1.5 cm. This option is faster, but in some cases more expensive. Like brickwork, plywood is laid in staggered patterns. A gap of a few centimeters between the sheets compensates for expansion when air humidity increases.

Common mistakes when building without a project

The most common mistakes when constructing buildings without drawings relate to planting a house on a site, supplying communications, structures, external walls, layouts, and life support systems.

General plan

When determining the location of the house on the site, an inexperienced builder faces difficulties:

Violation of the red line - the building must be located at a certain distance from the official building line along public roads; if this parameter is violated, demolition is threatened.
Going beyond the border of the plot - on lands without land surveying, when the boundaries of the plot are not fixed by boundary signs, there is the possibility of planting a house close to the border of a neighboring plot or on the land of another owner. If you do not agree with your neighbor on the purchase of the disputed piece, the result will be a lawsuit and demolition at the expense of the violator.
The supply of communications to the building requires special precision: the general plan diagram shows the coordinates of the connection points for electricity, gas, heat, water supply and sewerage. The places where the networks pass through the foundation must correspond to these coordinates.

Without geodetic surveying, it is impossible to accurately place the house on the general plan and connect it to networks. Any mistake of a few centimeters can lead to the dismantling of an expensive foundation.

Constructive decisions

For the longevity of a building, a proper foundation is necessary. Its design and depth are determined by: the geological composition of the soil, the depth of groundwater, the material of the walls, roof and the number of storeys of the house. If at least one of these factors is not taken into account, the entire structure may collapse:

on weak subsidence soils, uneven settlement will lead to the appearance of cracks;
the spring rise in water level will undermine the weak foundation;
brickwork is heavy, and a foundation not designed for it threatens to lose stability;
a one-story house can be placed on a shallow foundation; for a 3-story mansion, a different type of more powerful foundation is needed;
the roof protects the walls and interior from precipitation, saves up to 30% of heat; poor design of the roof or drain will lead to rapid failure of thermal insulation, snow melting in winter, and wet walls in spring and autumn.

Interfloor ceilings, load-bearing and enclosing roof structures, walls or frames also require calculations and drawings. This guarantees the selection of the optimal thickness of the elements, eliminates waste of materials - the construction will become more economical.

The consequences of an incorrectly designed foundation, walls, and roof pose a threat to the stability of the entire building. But having a drawing in hand, you can make a claim to the developer. Without a project, all costs are at the expense of the owner.

Space-planning solutions

Regulatory documents have their own requirements for planning decisions of individual residential buildings. They concern:

placement of boiler rooms, furnaces;
width of escape routes;
the angle of inclination of the stairs and the size of the steps;
heights and sizes of living rooms.

It is difficult, and sometimes impossible, for a non-specialist to find the right solution that combines the requirements of the lifestyle, the number of family members and building regulations. An inconvenient layout, too steep a staircase can sometimes even aggravate family relationships.

Due to rising prices for coolants, energy saving becomes relevant. Up to 30% of heating costs can be saved with the correct design of the fence: walls, roof, windows and doors. The thickness of the wall or the method of insulation is determined by thermal engineering calculations, and not by the “diagnosis” of the shabashnik - for this wall 5 cm of polystyrene foam is enough. The choice of insulation system and material affects the appearance of the building and also requires a professional approach.

Engineering systems

Do you want to live in comfortable conditions? This means that it is necessary to build in such a way that the house is warm, light, dry and safe. In private cottages, complex control and life support systems are often installed. This includes autonomous heating and hot water supply, own power plants - solar panels or geothermal, and smart home systems. The creation and installation of all this equipment requires knowledge and qualifications. The most common mistakes of amateur builders in this part:

Electrical network – the load is incorrectly determined, resulting in a power outage when a set of home appliances is operating.
Heating – the number of appliances is not able to create a comfortable temperature in cold weather.
Water supply is wasteful and often of poor quality.
Ventilation – the appearance of fungus, mold, drafts and unpleasant odors.

An amateur approach to resolving any issue leads to property damage and high operating and repair costs.

Using a pit

This is a rather unique way of building a house without using the classic type of foundation. It is necessary to dig a pit approximately 1 m deep. After this, fill it with crushed stone and stones of as large a fraction as possible. You can also add river sand diluted in water. At the top of the pit it is necessary to lay bricks or stones to a height of 20 cm from the top of the soil.

After this, fill everything with cement mortar. A frame house can be installed on top of the masonry. Houses that are installed on a foundation pit do not develop cracks or shrink, even if several decades have passed since construction.

Application of car tires

In order to build a small frame house, you can use simple car tires. It is necessary to lay a bandage beam on them. This material is the most accessible and cheap, and can last quite a long time. In order to equip the base for a frame house, you need to pour sand inside the tires about 3/4 of the height. From time to time it will need to be watered and compacted.

After this, fill the tires to the brim with crushed stone. As a result of the work carried out, you will receive a good alternative to a conventional foundation. Here's how to make a house without a foundation - just put a few tires on it. The base has the following advantages:

The foundation has very good shock-absorbing qualities. You can protect your entire house from seasonal swelling of the soil.
By erecting such a foundation, you will not violate the overall environmental friendliness of the entire building.
On what basis will you get a very stable structure. Judging by the reviews of people who chose just such a foundation for construction, we can conclude that there are no wall distortions at all, and door and window openings are also stable.
The cost of building such a base is very low; tires can be found for free at any tire shop.
Installation is very simple, as is the device, so this base has earned popularity among builders.

Such a foundation shows itself very well in the construction of a sauna or bathhouse, outbuildings, gazebos, and other buildings.

Useful advice from professionals

The following recommendations from professional builders will help you build the highest quality and strongest foundation that will withstand all expected loads:

Pay special attention to waterproofing work - this will prevent the concrete structure from becoming saturated with moisture, which means it will protect against the consequences of freezing in the thickness of the concrete, damage to the reinforcing frame by corrosion and other negative factors. The manufacture of a reinforcing frame is carried out only using knitting wire. Welding reduces the strength characteristics of metal rods. High-quality insulation of the tape itself and the blind area around the perimeter of the building minimizes the impact of frost heaving on shallow foundations. Concreting the foundation is best done in the warm season - at above-zero temperatures, the concrete matures faster and better. Experts recommend continuing construction work no earlier than 3-4 weeks after concreting the foundation - the concrete must gain sufficient strength

Immediately after pouring, the tape should be covered with polyethylene to prevent accelerated evaporation of moisture. During the first week, the base must be moistened regularly to avoid cracking.

Is it necessary to register a house in SNT?

As of 2021, the entire process of registering property rights in relation to summer cottages has changed slightly. A little earlier, it was possible to register any construction using one document. And the role of this document was the declaration of real estate. But some amendments to the law require a whole package of documentation. Due to this, in order to register, you will need a basic technical plan, which is created by an engineer of the cadastral department. A little earlier, it would have been enough for the owners to pay a state fee of 350 rubles and, of course, they would need to fill out a declaration.

Now, before completing the documentation for the property, you will need to spend extra money on the services of cadastral employees. And then the completed documentation will be submitted to Rosreestr. And only after registration has been completed, the owner of the dacha building can become the official owner. But here, nevertheless, you have to understand that the legislator will not additionally formalize the right to property if it concerns garden and dacha buildings.
