Blocked houses and semi-detached buildings. What it is? on the Nedvio website

What is considered a semi-detached house by law?

The norms of the Russian town planning code define several types of low-rise residential development. One of these types of housing is blocked houses.

The main definitions and technical provisions relating to blocked residential development are given in the Town Planning Code of the Russian Federation (Article No. 49, Part 2):

A blocked
residential building
is an apartment-type building consisting of two or more apartments, each of which has direct access to the adjacent plot. The building itself is considered a single house, although it consists of several, essentially autonomous residential blocks.

We will look at all the differences and rules for the development and operation of blocked houses a little later. Now let's move on to the background - how did this type of housing appear and why is it so in demand?

Registration stage:

4.1. Obtaining permission to put the facility into operation

To receive it, you must submit a corresponding application to the local government body (LSG) in person or through the MFC or electronically.

The following documents must be attached to the application:

• title documents for the land plot;
• urban planning plan of the land plot submitted to obtain a building permit;
• building permit;
• act of acceptance of a capital construction project (in the case of construction or reconstruction on the basis of a construction contract);
• an act confirming the compliance of the parameters of the constructed capital construction facility with the design documentation, including the requirements for energy efficiency and the requirements for equipping the capital construction facility with metering devices for energy resources used, and signed by the person carrying out the construction (the person carrying out the construction, and the developer or technical customer in the case of construction, reconstruction on the basis of a construction contract, as well as by the person exercising construction control, in the case of construction control on the basis of a contract);
• documents confirming the compliance of the constructed or reconstructed capital construction facility with technical conditions and signed by representatives of organizations operating engineering support networks (if any);
• a diagram showing the location of the constructed or reconstructed capital construction project, the location of engineering and technical support networks within the boundaries of the land plot and the planning organization of the land plot and signed by the person carrying out the construction (the person carrying out the construction, and the developer or technical customer in the case of construction, reconstruction on based on a construction contract), with the exception of cases of construction or reconstruction of a linear facility;
• the conclusion of the state construction supervision body on the compliance of the constructed or reconstructed capital construction project with the requirements of design documentation, including the requirements of energy efficiency and the requirements for equipping the capital construction project with metering devices for the energy resources used, the conclusion of the federal executive body authorized to carry out federal state environmental supervision;
• technical plan of a capital construction project, which is prepared by a cadastral engineer for each block of a residential building separately, indicating the cadastral number of the land plot on which this block is located.

History of the format

This format of low-rise buildings first appeared in England and France, and received special development in the 17th – early 20th centuries.

Thus, the first street consisting entirely of interlocking buildings appeared in Paris in the early 1600s. In Britain, such development began to be widely used in urban planning after the great fire that occurred in London in 1666.

Since the late 18th and early 19th centuries, when Britain was undergoing massive urbanization, standard block housing has become prevalent in growing industrial centres. In conditions of large population concentrations and lack of space for the construction of individual households, this type of housing has become widely in demand.

Other obvious advantages of block development are:

1. Significantly lower cost per square meter;
2. Improved layouts, often larger area;
3. More comfort compared to apartments, using some of the advantages of a country house (such as its own plot, separate entrance, etc.);

As a result, by the end of the 19th century, most cities in Great Britain began to consist of long rows of narrow streets lined with block-type houses.

Then, from England, semi-detached residential development “migrated” to other countries and territories associated with the British Empire: to the USA, India, Australia. Also, this type of residential buildings has become widespread in Scandinavia and Germany.

Design of blocked residential buildings and its features

Blocked houses, often called townhouses, have long become a familiar and widespread type of housing in Europe, but in our country they are not yet so common.
Recently, in this regard, there has been a tendency to increase the share of blocked houses in the Russian housing stock, which is explained by the high cost of real estate and the shortage of land for development in cities. Initially, back in the 90s of the last century, when townhouses began to appear in Russia, this housing option belonged to the concept of economy class, but in modern conditions the scope of ideas about blocked houses has expanded significantly. Nowadays you can still find townhouses that belong specifically to this category of housing, but you won’t surprise anyone with premium options, and all thanks to the development of construction technologies, which allows you to create block-type residential buildings at the highest level of comfort. Of course, all this becomes possible only with the right approach to the construction of this type of housing, first of all, this concerns the issue of developing designs for these houses. Accordingly, serious attention must be paid to the design of blocked residential buildings so that the resulting result does not upset apartment owners with its level of quality and does not create obstacles for them to have a normal and fulfilling life.

What are the differences between a blocked house and an apartment building?

Being essentially a low-rise building with several apartments, a semi-detached house can be quite difficult to distinguish from ordinary multi-apartment residential complexes. However, it has several major differences.

Thus, according to the law, a blocked building must meet the following requirements:

1. The number of floors in the house should be no more than 3;
2. The total number of blocks in the building should be from 1 to 10;
3. Each of these residential blocks is designed for autonomous living of one family, and is a separate comfortable apartment;
4. Neighboring apartments (blocks) are separated from each other by blank walls, without doorways;
5. Residents of semi-detached houses do not have common property (i.e. common entrances, attics or basements, communication shafts, etc.);
6. Each family has a separate exit to the local area, without a common corridor or entrance (front door).

The main difference between blocked buildings and a standard apartment building, from the point of view of Russian legislation, is the design of the local area. If all the land under a multi-apartment residential complex is registered as 1 plot, then in semi-detached buildings a separate plot of land is registered for each block.

There is also quite often confusion in the use of terms: what is “block housing”? Are they the same thing as "townhouses" or "duplexes"?

About land plots

The residential area "Harmony" includes different types of development according to individual projects:

• Mid-rise multi-apartment residential development (considered 4 to 8 floors);
• Individual development (townhouses, duplexes, flathouses and mansions);
• Commercial premises (shops, etc.);
• Social construction (kindergarten, sports complex), including religious ones (Church of St. Artemy, spiritual and educational center, House of Mercy);
• Engineering infrastructure (gas supply, electricity supply, water supply, sewerage, roads);
• Landscaping (Swallows Alley, recreation areas, art objects, sports grounds).

The construction of houses in the residential area "Harmony" near Stavropol is guided by the Civil Code of the Russian Federation. The planning and development of the territory is designed for the next 5-10 years according to the master plan for the development of the city of Mikhailovsk.

The main urban planning document for the Harmony residential area is an approved project for planning the development of an area of ​​702 hectares. At the moment, the first stage of development of 182 hectares has almost been completed.

Planning takes into account:

• Number of inhabitants;
• Number of housing units;
• Social facilities;
• Engineering infrastructure facilities.

Based on this, the building density and the number of people per 1 square meter are calculated. meter.

Regulatory framework

The procedure for operating semi-detached housing, as well as construction and technical standards, are determined by the following legal acts:

• Housing legislation of the Russian Federation. It contains the basic concepts and definitions of block houses, and their operational and technical characteristics;
• Town Planning Code (Article No. 49). Contains a precise and comprehensive definition of semi-detached development;
• Decree of the Government of the Russian Federation No. 220, dated 2015, establishing the procedure for purchasing blocked housing on the primary market;
• Federal Law No. 161, as well as Order of the Ministry of Construction No. 223, defining the rules for the provision of land plots for the construction of combined residential buildings;
• Land Code of the Russian Federation (Article No. 35), which regulates the procedure for legal registration of plots intended for block development;
• Letter from the Ministry of Economic Development stipulating the procedure for placing interconnected buildings on one plot of land.

In accordance with these legal acts, a full range of legal registration of blocked development is carried out, starting from the allocation of land for construction, and ending with the purchase and registration of finished housing.

Preparatory stage:

Before starting construction work, you need to carry out several preparatory procedures:

2.1. Preparation of project documentation

Preparation of design documentation for a residential building in a blocked development is mandatory.

The project is ordered by the owner (owners) of the land plot from the design organization and prepared by it on the basis of the following documents:

• urban planning plan of the land plot;
• results of engineering surveys (if they are missing, the contract for the preparation of design documentation must provide for the task of performing engineering surveys);
• technical conditions (if the functioning of the designed capital construction facility cannot be ensured without connecting (technological connection) such a facility to engineering support networks).

2.2. Taking into account building codes and regulations during design

When designing and constructing a residential building in a blocked development, it is necessary to comply with the construction, sanitary and fire safety standards and rules contained in the Land Code, Town Planning Code, SNiPs (building codes and rules governing construction, engineering and architectural surveys and town planning activities).

Of all the many SNiPs for individual housing construction, the following are important:

• SP 11-111-99 - development, coordination, approval, composition of design and planning documentation for the development of low-rise housing construction areas;
• SP 30-102-99 – planning and development of low-rise housing construction areas;
• SNiP 30-02-97 – planning and development of territories of gardening dacha associations of citizens, buildings and structures;
• SNiP 21-01-97; – Fire safety of buildings and structures;
• SP 55.13330.2016 - Code of rules. Single-apartment residential houses (or SNiP 31-02-2001).

2.2.1. Sanitary and fire safety standards and recommendations for interior spaces:

According to the requirements of SP 55.13330.2016, a house, including a block in a block house, must include one or more rooms, as well as auxiliary premises:

• kitchens, including kitchen niches and (or) kitchen-dining rooms;
• baths and (or) showers;
• toilet or combined bathroom.

In addition, built-in, built-in-attached and attached auxiliary premises can be arranged:

• utility rooms (storerooms);
• Built in furniture;
• auxiliary room for generator heating and (or) power supply;
• parking space at the house in accordance with SP 113.13330
• swimming pool in accordance with the requirements of SP 31-113-2004
• steam room, bathhouse or sauna in accordance with SanPiN 2.1.2.3150.

2.2.2. Sanitary and fire safety requirements for internal engineering networks

Technical conditions for connecting engineering and transport infrastructure in the adjacent environment are carried out in accordance with SP 42.13330.

2.2.3. Basic requirements for structural elements

The foundations and supporting structures of a residential building in a blocked development must be designed and constructed in such a way that during the construction process and in the design operating conditions, the possibility of destruction or damage to structures and unacceptable deterioration in the operational properties of structures leading to the need to cease operation of the house is excluded. When designing a roof, you should be guided by the provisions of SP 17.13330.

The structures and foundations of the house must ensure reliability during their service life in accordance with the requirements of GOST 27751 and be designed to withstand standard loads and impacts in accordance with SP 20.13330.

The foundations of the house must be designed taking into account the physical and mechanical characteristics of soils in accordance with SP 22.13330 (for permafrost soils in accordance with SP 25.13330), the characteristics of the hydrogeological regime at the development site, as well as the degree of aggressiveness of soils and groundwater in relation to foundations and underground utility networks. Foundations must ensure the necessary uniformity of settlement of the foundations under the elements of the house. Pile foundations should be designed in accordance with SP 24.13330.

Blocks in a block building should be separated by blind fire walls with a fire resistance rating of at least REI 45 and a fire hazard class of at least K1. Blocked houses of structural fire hazard classes C2 and C3 must additionally, in accordance with SP 4.13130, be divided by blind fire walls of the 1st type with a fire resistance limit of at least REI 150 and a fire hazard class of at least K0 into fire compartments with a floor area of ​​no more than 600 m2, including includes one or more residential blocks.

When designing and constructing houses of blocked development, measures must be taken to prevent the spread of fire from one residential autonomous block to another and to other fire compartments, bypassing fire barriers. To do this, fire walls must cross all house structures made of flammable materials.

Each residential autonomous block of a blocked building must have at least one emergency exit to the outside, including to a type 3 staircase in accordance with SP 1.13130.

A residential building in a blocked building must be designed, constructed and equipped in such a way as to prevent the risk of injury to residents when moving in and around the house, when entering and exiting it, as well as when using indoor equipment.

2.3. Obtaining a building permit.

To obtain a construction permit, the owner of the land plot or his official representative must apply for a construction permit to the local government body (LGU) in person or through the MFC or electronically.

The following documents must be attached to the application:

• title documents for the land plot;
• urban planning plan of the land plot, issued no earlier than 3 years before the date of submission of the application for a building permit;
• materials contained in the design documentation:
• explanatory note;
• a diagram of the planning organization of the land plot, made in accordance with the information specified in the urban planning plan of the land plot, indicating the location of the capital construction project, entrances and passages to it, the boundaries of public easements, archaeological heritage sites;
• a diagram of the planning organization of the land plot, confirming the location of the linear object within the red lines approved as part of the territory planning documentation in relation to linear objects;

More details

The development of the SPZU is carried out in accordance with the norms of the Land Use and Development Rules (LRU) of the zone to which the original land plot belongs, and in accordance with the requirements set out in a number of regulatory documents:

1. SP 30-102-99 “Planning and development of low-rise construction areas”;
2. SP 42.13330.2016 “Urban planning. Planning and development of urban and rural settlements”;
3. SNiP 31-02-2001 “Single-apartment residential houses”;
4. “Regulations on the composition of sections of project documentation and requirements for their content” Decree of the Government of the Russian Federation No. 87 dated February 16, 2008.

The construction of a blocked residential building must be carried out on a single original plot of land or on several adjacent land plots for blocked residential development, and therefore permitting documentation for construction is issued taking into account the specific situation.

Blocked house - is it private or shared?

This is one of the most common questions that causes confusion and uncertainty among all those who are planning to buy a townhouse or duplex, or have already purchased. What is private in such houses and what is common?

There is simply no answer to this question. Due to the “youth” of this housing format on the Russian market and the large number of regulatory documents, many of them provide vague definitions, or even completely contradict each other.
