The technical underground is a room in the underground part of the house, in which communications are laid and equipment is placed. In other words, it is a technical floor located at the bottom of the house. In general, in residential buildings, the technical floor can be a basement, an attic or the space between aboveground floors.

The basement is considered a technical underground only if it complies with the current building codes and regulations (SNiP) at the time of the construction of the house. The definition of technical underground is given in SNiP for residential buildings.

Why is there this difference and what is the difference for the owner? The technical underground is not taken into account in the cadastral valuation, and therefore is not taxed like a dwelling. To understand the structure of the technical floor and the difference between the basement and the underground, one should study the standards that are used in the BTI when decorating a building.

What is a technical floor?

The technical room is equipped on the basis of the approved project of the house. Its location also depends on the total number of floors. There are several such premises if there are many apartments in the house.

The technical floor can occupy:

• basement;
• attic;
• space between residential floors.

In a standard nine-story building, technical undergrounds are made under the first floor or they connect the underground with the basement. If there are more floors, they will additionally equip a technical attic. Very tall buildings with more than sixteen floors must have technical floors every 50 m. This allows you to control the hydrostatic head in water supply pipes and heating systems.

The technical floors are separated from the residential part of the building. They place equipment for servicing the communal needs of residents:

• boiler rooms;
• water supply pipes;
• heating systems;
• sewerage;
• backbone networks of electrical equipment;
• electrical panels;
• pumps;
• ventilation networks;
• air conditioning systems;
• machine rooms for elevators.

The height of the technical floor corresponds to the height of the equipment that is supposed to be placed in it (but at the same time it should not be less than the established norms). The load from the work of engineering equipment is calculated on the basis of regulatory documents.

The equipment room can be located at the bottom of the house, under the roof, or between floors.

Since the operation of communal systems creates noise and vibration near apartments, the technical attic or technical underground must be soundproofed. The technical room, located between the floors, is equipped with shock-absorbing systems, and elastic materials are placed under the equipment to further absorb vibration.

The technical floor and the equipment in it are the collective property of all residents of the building. The ZhEK or other service organization has access to it. A functional technical floor cannot be fully transferred to the ownership of one of the apartment owners.

Basic documents

During the construction, design and operation of technical floors, the norms enshrined in documents such as:

• SNiP 2.08.01 of 1989 for residential buildings;
• SNiP 31-02 of 2001 for single-family residential buildings;
• SNiP 31-06 of 2009 for public buildings that are in the same building as residential;
• SNiP 31-01 of 2003 for apartment buildings (updated edition of SP 54.13330 2011).

Dimensions of technical floors

Requirements for technical premises are indicated in SNiP 2.08.01-89 regarding residential buildings. So, the height of the technical attic should be at least 1.6 m, and the width of its passage should be 1.2 meters. In some areas, it is allowed to reduce the height to 1.2 m and the width to 0.9 m.

The height of the basement, in which the heating and water supply pipes are located, must be at least 1.8 m, and in the area where non-combustible materials are used, the height can be reduced to 1.6 m.

According to the fire safety rules, the technical floor is divided by partitions into sections up to 500 sq. m, or within each section of a residential building with several entrances.

Service personnel must have free access to any area of ​​communications.

The height of the technical underground and its equipment

SNiP 31-01-2003 defines the technical space in the basement of a residential building, which is used exclusively for utilities and equipment and is not considered part of the living space.

1. The technical underground must not be less than 1.6 m in height (in the case of transit pipelines, at least 1.8 m).
2. It should have a through passage 1–1.2 m wide for equipment control and repair work.
3. In addition to the main passage for personnel, openings for pipelines are made in the partitions of the compartments, taking into account insulation.
4. There should be uniform artificial lighting along the aisle with a switch at the entrance.
5. For the passage through the pipes of heating and water supply, wooden floorings with walkways are made.
6. The room is equipped with a staircase and a door that opens outward.
7. Since dampness forms in the technical underground, and condensation settles on the walls, reinforcement with increased corrosion resistance should be used.

For subsequent repair or replacement of pipes, technical undergrounds at the end must be equipped with mounting holes, the size of which is 90 x 90 cm. External mounting holes are sealed in such a way that, if necessary, they can be opened without violating the integrity of the wall.

Ventilation in the technical underground

Fresh air must be regularly supplied to technical rooms through exhaust ducts and windows. According to SNiP, in the technical underground of a residential apartment building, air vents must be made to circulate air, reduce condensate and for fire safety purposes.

The standards prescribe to make ventilation holes with a total area of ​​at least 1/400 of the area of ​​the basement itself or the technical underground. The holes are placed symmetrically on both sides of the house. It is recommended to make airflows approximately 20 x 20 cm at a height of 30-40 cm from the level of the outer blind area of ​​the foundation.

Examples of airflow devices.

Also in the technical underground they make dry insulated chambers with equipment for supply and exhaust ventilation. They are provided with access for inspection and repair.

In winter, in basements and technical undergrounds, the air temperature is maintained at least 5 ° C, while the relative humidity should be no more than 60–70%. To eliminate heat loss in the technical underground, walls and ceilings are insulated. Heating and water pipes are wound with heat-insulating materials.

If excess condensation or mold appears on the equipment in the technical underground, additional waterproofing should be done and ventilation should be carried out through the doors and windows, installing protective grilles on them. In blank walls, at least two air vents are knocked out for each section from both sides of the foundation.

The difference between the technical underground and the basement

The basement is classified as a floor and is included in the cadastral valuation of the house. At the expense of the basement, you can expand the living space or make a storage room in it. Unlike the technical underground, the basement of an apartment building is allowed to be rented out for business, subject to the consent of all residents.

The technical underground can be combined with the basement, or it can be built on its own. The SNiP defines the technical underground, according to which this is a room in the lower part of the building, which is intended exclusively for equipment and communications.

In the editions of SNiP 31-06-2009 for public buildings, it is indicated that the height of the underground must be at least 1.8 m in the passage for service personnel. To comply with fire safety rules, the height of the space where the power grids and pipes are located must be at least 2 m.

However, if you evaluate the premises according to the norms of SNiP 31-01-2003 for residential buildings, the technical underground with a height of up to 1.8 m is not considered a floor and is not taxed. Such a point should be taken into account by developers of small-apartment and private houses that are not combined with public buildings by a common basement.

During construction, a technical floor with complex large-sized equipment can be placed in the basement and a technical underground for communications can be made.

Vulnerabilities in the construction of technical floors

In the technical underground, high humidity can remain, as a result of which moisture appears in the floor and on the walls of the foundation. The reinforcement rusts, the wooden flooring and the heat-insulating winding of the pipes are destroyed. If there is insufficient drainage, the technical underground can become flooded.

Leakage requiring immediate repair.

During the repair and reconstruction of the technical underground, attention should be paid to such problems as:

• insufficient air circulation in the room;
• malfunction of ventilation systems, as a result of which dampness and mold appear;
• destruction of thermal insulation and waterproofing on pipes, which causes corrosion;
• worn out wiring parts;
• ineffective and clogged drainage systems;
• subsidence of the foundation and supports under plumbing communications;
• the gaps between the foundation and the blind area from the outside, through which precipitation penetrates into the technical underground.

Sometimes during the reconstruction process it is required:

• increase the height of the room;
• install additional supports for equipment;
• make openings in load-bearing walls;
• to make collectors for collecting sediments and equip drainage channels.

These works are carried out according to the previously approved construction plan.

I can’t figure it out myself in the IZhS Town Planning Code, and the letter of the Ministry of Economic Development of the Russian Federation dated 03/20/13 No. OG-D 23-1426 did not clarify. The cadastral engineer said that MAYBE I will not be able to obtain a certificate of ownership of a residential building, since the number of floors is 4 (four). A house for 1 family in a rural area (near Rostov-on-Don) is 10m by 10m. According to the plan: the basement floor - the top of the basement floor overlap rises 1.7 meters above the level of the ground level - and 2 (two) aboveground floors. In fact: the attic floor has been added. Is the basement floor considered in my case (there are 3 rooms in it - a boiler room, a storage room and a third room without an appointment) as a FLOOR? What if the answer is YES? We are all now without a registration, since the only apartment was sold to complete the construction. Please, tell me what to do?

LETTER
dated 03/20/2013 No. OG-D23-1426
On determining the number of floors and number of storeys and criteria for classifying buildings as objects of individual housing construction

MINISTRY OF ECONOMIC DEVELOPMENT OF THE RUSSIAN FEDERATION

From 20.03.2013 No. OG-D23-1426

The Real Estate Department of the Ministry of Economic Development of Russia (hereinafter referred to as the Real Estate Department) reviewed the appeals dated February 12, 2013 and reports.

In accordance with the Regulations on the Ministry of Economic Development of the Russian Federation, approved by Decree of the Government of the Russian Federation No. 437 dated June 5, 2008, the Ministry of Economic Development of Russia is not empowered to clarify the legislation of the Russian Federation, as well as the practice of its application.

At the same time, we believe it possible to note the following on the issues raised in the appeal.

1. On entering into subsection I of the Unified State Register of Rights to Real Estate and Transactions with It (hereinafter - USRR) information on the number of floors of a building, structure during state registration of rights.

Based on the provisions of clause 1.2 of part 1 of article 20 of the Federal Law of July 21, 1997 No. 122-FZ "On state registration of rights to real estate and transactions with it" (hereinafter - the Law on Registration), clause 23 of the Rules for maintaining the Unified State Register of Rights for real estate and transactions with it, approved by the Government of the Russian Federation of February 18, 1998 No. 219, subsection I of the USRR contains a brief description of the immovable property on the basis of documents certified by the organization (body) for registering immovable property in the territory of the registration district. Entries in subsection I of the USRR can be made on the basis of other documents in cases established by the Registration Law.

Thus, information about a real estate object in subsection I of the USRR is entered on the basis of information contained in the state real estate cadastre.

The above information on the number of floors of a building, structure is entered into the state cadastre of real estate when such buildings, structures are registered with the state cadastral registration on the basis of a technical plan prepared by a cadastral engineer.

According to clause 42 of the Requirements for the preparation of a technical building plan, approved by order of the Ministry of Economic Development of Russia dated September 1, 2010 No. 403 (hereinafter - Requirements), in the corresponding lines of column "3" of the "Building characteristics" table of the technical building plan on the basis of the documents specified in clause 12 Requirements, information about the number of floors of the building (including underground) is entered. If there are no underground floors of the building, the “-” (dash) sign is put on the corresponding line.

Similar requirements are contained in the Requirements for the preparation of a technical construction plan, approved by order of the Ministry of Economic Development of Russia dated November 23, 2011 No. 693.

2. About determining the number of floors and number of storeys.

In accordance with clause 19 of part 2 of article 7 of the Federal Law of July 24, 2007 No. 221-FZ "On the State Cadastre of Real Estate" (hereinafter - the Law on the Cadastre), information on the number of floors (number of storeys), including underground floors, if the real estate object is a building or structure (if the building or structure has a number of storeys).

According to the Instruction on accounting of the housing stock in the Russian Federation, approved by the order of the Ministry of the Russian Federation for Land Policy, Construction and Housing and Communal Services No. 37 dated August 4, 1998 (hereinafter referred to as the Instruction), the floors of residential buildings include:

Attic floor (attic) - a floor in an attic space, the facade of which is fully or partially formed by the surface (surfaces) of an inclined or sloping roof, while the line of intersection of the plane of the roof and the facade should be at a height of no more than 1.5 m from the floor level of the attic floor;

Above-ground floor - a floor when the floor level of the premises is not lower than the planning level of the ground;

Basement floor - a floor when the floor of the premises is below the planning level of the ground by more than half the height of the room;

Technical floor - a floor for placing engineering equipment and laying communications; can be located in the lower (technical underground), upper (technical attic) or in the middle of the building;

Ground floor - a floor when the floor of the premises is below the planning level of the earth to a height of no more than half the height of the premises.

Also, according to the Instructions, the number of storeys of a residential building should be determined by the number of above-ground floors. When determining the number of storeys, basement floors are included in the number of overground floors if the top of the basement floor overlap rises above the level of the planning level of the ground by at least 2 m.

The current legislation does not contain a definition of the term "underground floor". At the same time, in the opinion of the Real Estate Department, all floors of a building, structures that are not related to above-ground floors are underground floors (basement, ground floor, if the top of its floor is less than 2 m above the average planning level of the earth).

In accordance with SNiP 2.08.02-89 * "Public buildings and structures", when determining the number of storeys of a building, the number of floors includes all above-ground floors, including the technical floor, the attic, as well as the basement floor, if the top of its floor is above the average planning mark land for at least 2 m. The underground for ventilation under buildings designed for construction on permafrost, regardless of its height, is not included in the number of above-ground floors. The technical floor located above the upper floor is not taken into account when determining the number of storeys of the building.

In Appendices B and C of SNiP 31-01-2003 "Residential apartment buildings" definitions of floors and rules for determining the number of storeys of a building are given. When determining the number of storeys of a building, all above-ground floors are included in the number of above-ground floors, including the technical floor, the attic, as well as the basement floor, if the top of its floor is at least 2 m higher than the average planning level of the earth. The underground under the building, regardless of its height , as well as interfloor space with a height of less than 1.8 m, are not included in the number of above-ground floors.

Thus, the number of storeys should be understood as the number of overground floors, including a technical floor, an attic, and a basement floor, if the top of its floor is at least 2 m higher than the average planning level of the earth.

The term "number of floors" is enshrined in article 49 of the Urban Planning Code of the Russian Federation as a criterion for determining the need for a state examination of project documentation and cannot be replaced by the term "number of storeys".

Thus, the number of floors should be understood as the number of all floors, including underground, basement, basement, aboveground, technical, attic.

At the same time, we would like to inform you that the Ministry of Economic Development of Russia is currently working on the draft federal law No. 54480-6 "On Amending Certain Legislative Acts of the Russian Federation Regarding State Registration of Rights and State Cadastral Registration of Real Estate Objects", adopted by the State Duma of the Russian Federation in the first reading on December 11, 2012, according to which it is envisaged to exclude information about the number of storeys from the data of the state cadastre of real estate, provided for by the provisions of paragraph 19 of part 2 of article 7 of the Law on the Cadastre.

3. On the criteria for classifying buildings as objects of individual housing construction.

According to part 2 of article 16 of the Housing Code of the Russian Federation, a residential building is an individually defined building, which consists of rooms, as well as premises for auxiliary use, intended to satisfy citizens' household and other needs associated with their residence in such a building.

Based on the provisions of Part 3 of Article 48 of the Town Planning Code of the Russian Federation, individual housing construction objects are detached residential buildings with no more than three floors, intended for one family, in respect of which the preparation of project documentation is not required for construction, reconstruction, overhaul ...

In accordance with clause 6 of the Regulation on the recognition of premises as residential premises, residential premises unsuitable for living and an apartment building as hazardous and subject to demolition or reconstruction, approved by Decree of the Government of the Russian Federation No. 47 of January 28, 2006, an apartment building is a combination of two or more apartments, having independent exits either to a land plot adjacent to a residential building, or to common areas in such a house.

Thus, detached residential buildings with more than three floors (when calculating the number of floors of which all floors in the building are included) do not belong to individual housing construction.

Apartments on the last floors are not very popular, since residents of such apartments often have to solve problems with roof leaks on their own. However, the location of the apartments in some cases provides a unique opportunity to expand the living space and turn a standard apartment into a two-level one. This can be done by attaching a part of the attic space located directly above the apartment, and the experts of the portal site will tell you about how realistic this plan is and how to accomplish this in this article.

Targets and goals

Attic spaces are an essential element of a multi-storey building project, however, for the most part, these spaces are not used in any way. For joining a part of the attic, apartments on the top floor of a house with a sloping roof are best suited, since the height of the attic makes it possible to create there the conditions necessary for a comfortable stay. Most often, the technical possibility of connecting a part of the attic is available, since the purpose of the attic assumes the possibility of the periodic presence of people there (to carry out maintenance of passing communications, etc.). That is, the bearing plane of the attic floor is able to withstand loads comparable to those arising from the operation of residential premises.

Legal Issues

However, you cannot live in the attic, since, from the point of view of the law, the attic is not a living space. Therefore, for the attic to acquire the status of a dwelling, it must be appropriately equipped, turning it into an attic floor, for the operation of which as a dwelling there will no longer be any claims. But the attic space is not "nobody's", therefore, in order for the owner of the apartment on the top floor to be able to carry out any work, and then join part of the attic area to the area of ​​his own apartment, and use this area, it is necessary to formalize property rights. In addition, it is also necessary to legalize the changes made, otherwise the representatives of the regulatory authorities may oblige to “return everything as it was”, as well as impose a fine.

The right to dispose of the attic space

So, in order to use the attic area, you must first obtain the right to dispose of this area, that is, you need to transfer the rights from the current owner. The attic space (in most cases) is part of the common property of the residents of an apartment building, like any room in the house (basement, stroller, concierge room, other household premises) that is not someone's private property. Therefore, to connect the attic, you need permission from the general meeting of owners. It will not be easy to obtain such consent, but it is possible.

Action plan

An approximate plan of action on the last floor, who wants to join part of the attic area, will look like this:

1. Obtain confirmation of the technical feasibility of performing the conversion of the attic and its further operation as a living space;

2. To issue property rights to a part of the attic space, by agreement with the tenants of the house;

3. Obtain permission to carry out work on the reconstruction of the attic;

4. Carry out reconstruction works;

5. Obtain permission to put the attic into operation;

6. Officially register the resulting living space.

Expertise

Before entering into negotiations with neighbors (which is one of the most difficult parts of the project), it is necessary to get answers to the following questions:

• Will it be possible to make an attic room suitable for living out of the attic, and will the reconstruction work cause damage to the integrity of the building, its individual elements;
• Will it be possible to obtain permission from the regulatory authorities to carry out work (and, accordingly, subsequently register the premises as living space).

The answer to the listed questions can be given by an official conclusion, which is issued on the basis of an examination. To conduct an examination, contact the state regulatory authorities (the first instance will be the city architectural inspectorate). The official conclusion of the state body will be a sufficient basis for obtaining permission for the reconstruction of the attic space.

Funding amounts

An additional result of the examination will be an understanding of the amount of money that will have to be spent directly on construction and finishing work, as well as on the solution of organizational issues, which will be described below. In other words, it will become clear - "is it worth the candle," in some cases it may turn out that it is easier and cheaper to purchase a more spacious apartment than to engage in attaching an attic space. However, if we are talking about an apartment in a metropolis, we can almost certainly say that it is more profitable to attach a part of the attic space than to exchange an apartment for a more spacious one (not to mention a two-level apartment).

Property rights

The attic space belongs to all tenants of the house, therefore, their consent is necessary for part of the total area to be operated by the owner of one apartment. The only way to obtain a collective decision is to hold a meeting of owners, who, by law, can give their consent to the following actions:

• Reconstruction of the attic space with a decrease in the share of common property. In other words, the tenants agree to transfer part of the attic to the ownership of the owner of one of the apartments; to make such a decision, the unanimous approval of the collective meeting is necessary;
• Carrying out reconstruction without reducing the share of common property. In this case, part of the attic can be transferred on a long-term lease or for free use. That is, useful square meters remain the property of the tenants' collective, but the owner of the apartment can use the attic on a lease basis. For this, unanimous approval is not required, it is enough for two-thirds of the collective to vote for this decision.

It is not easy to get the consent of the majority of tenants, and even more so, the unanimous decision of the collective. The complete lack of interest in someone expanding their living space is not conducive to making a positive decision, so some motivation is needed. Such motivation can be the carrying out of repair work in the house at the expense of those who apply for the attic, the arrangement of parking for the residents of the house, a playground, and other options.

However, making a decision is not enough to use the square meters of the attic space, the decision needs to be documented. That is, if the attic is leased, it is necessary to draw up and sign a lease agreement, but if the attic space becomes the property of the owner of the apartment (under this attic), then the registration procedure is somewhat different. Already on the basis of the relevant document, it is possible to take any action in relation to the attic space - to obtain permission for its reorganization (reconstruction), to carry out construction work and, in fact, to operate the area.

Obtaining permission for reconstruction

The basis for obtaining permission by the owner of the apartment for the reconstruction of the attic is, on the one hand, the decision on reconstruction made by the collective of tenants, and on the other hand, the document of title - the lease agreement (transfer agreement for gratuitous use).

In the event that we are talking about the transfer of the attic into ownership, then the permission for reconstruction is received by the collective of tenants, on whose behalf all the work is subsequently carried out, up to the receipt of documents on putting the attic into operation. After that, the premises are already transferred to the owner of the apartment under a sale and purchase agreement (as payment, the new owner of the attic can be indicated for any construction and repair work, etc.). This procedure somewhat complicates the task, since an additional link appears, a person who, on behalf of the collective of owners, will control all the actions of the applicant for the attic. In addition, this representative must also be interested in carrying out the work, which, in turn, is fraught with additional costs.

Before obtaining permission to convert the attic into an attic floor, you need to prepare a project. The project is made in public or private design organizations, the document must fully comply with building codes and regulations, must be agreed with a number of authorities (fire inspection, Ministry of Emergency Situations, sanitary and epidemiological station, etc.).

The permit is issued by a state body (Department of Urban Architecture), where it is necessary to submit an appropriate application, an agreed project, title documents.

However, one of the options for the development of events is the transition to construction work without obtaining permission, with the expectation of subsequently legalizing everything through the courts. However, this option is rather risky, and is fraught not only with the lack of the ability to draw up documents, but also with the danger of violating the integrity of the building, which may threaten to be prosecuted.

Carrying out works and commissioning

Having on hand documents confirming the right to carry out reconstruction, the owner of the future attic floor can begin work. All construction work must be carried out in strict accordance with the approved project, since after the completion of the work it is necessary to obtain a document confirming the commissioning of the attic floor. This document is issued on the basis of an acceptance certificate, which is signed by representatives of the housing inspectorate after inspection and in the absence of violations of the rules and regulations (as well as deviations from the project, on the basis of which the permission for reconstruction was issued).

Registration of documents for the real estate object

This is the last stage, completing the whole complex of measures for joining the attic space to the apartment area. If the area of ​​the attic was taken over, it is necessary to make changes to the documents for the apartment, since the number of square meters has changed, as well as the configuration of the apartment. In the event that the area of ​​the attic was leased, you need to fix the changes in the plan of the house (based on the results of the reconstruction). The bodies that should be involved at this stage are BTI and Rosreestr, and the following documents are the grounds for changing technical documentation and re-registering:

• An agreement confirming property rights;
• Reconstruction permit;
• Permission to enter the reconstruction object into operation;
• Project documentation.

Conclusion

Considering the issues related to the connection of the attic space, the experts of the website portal would like to add that, in parallel with the preliminary examination, it will be useful to find out if an application for intent to reconstruct the attic space has been submitted earlier. If such an application has been submitted, a detailed study of the issue will help save money already at the planning stage.

In addition, at the time of studying the issue, the attic may already be in someone's private property or, for other reasons, may not be the collective property of the residents of an apartment building. Choosing between public and private design organizations, it is best to opt for a company that has been recommended by representatives of the government agency, which will issue permission for the reconstruction of the attic. In other words, it may be a very reasonable decision to involve an intermediary organization (or a private person) that is professionally dealing with such issues.

When planning the construction of a house, almost every customer asks the question - what to build under the roof? Attic or attic space? What are the differences between these elements? The ability to separate the concepts of "attic" and "attic" is necessary not only because of the functionality of the premises under the roof, but also in order to avoid possible problems when registering a residential object.

The total usable area of ​​the house largely depends on the purpose of the roof space. Let us examine in more detail what is the difference between an attic and an attic in a private house.

Attic - general concepts

Many in the process of planning the construction of a private house dream of an attic, although the end result may differ from what is desired. Therefore, you should decide on the concept of an attic floor. A clear explanation is given by SNiP (building codes and regulations). Immediately, we note that all legal actions related to registration (re-registration in the BTI, and so on) are necessarily based on this set of laws.

According to SNiP 2.08.01-89 an attic or attic floor is the upper tier located in the attic space. Its facade is formed partially or completely by the roof plane of the building. The height of the walls formed should not exceed 1.5 meters from the floor level to the line of intersection with the roof surface, otherwise it is a full-fledged second floor.

Someone will object that his attic in a house made of timber has the same shape. It is quite possible, but the fundamental difference is that the attic room is a specially equipped and residential area under the roof of the house. This is the second main functional indicator. For this reason, the attic floor needs, especially for houses from a bar. Thermal insulation of additional living space requires additional costs, but as a result, the rooms will be fully suitable for long-term living. Installation of ventilation is mandatory. Without it, the ascending air currents from the lower floors will not allow residents to feel comfortable. In addition, the problem of condensation on walls and ceilings is immediately solved.

Attic - is it needed?

Under the attic space, most people mean a certain area under the roof, littered with various rubbish. Old things, household items and household items, spare parts - in general, everything that is a pity to part with for various reasons. SNiP considers the attic as a space between the roof structure, separated by external walls and not intended for living. If additional space is planned for placing engineering equipment and wiring communications, then it is customary to call it a technical attic. There are no other regulations that regulate the differences between the attic and the attic.

In contrast to the attic floor, the attic has a varied design.

According to its properties, the attic can be of two types:

• Cold... Insulation materials do not go beyond the boundaries of the floor slabs.
• Warm... In this case, the insulation is within the framework of the roof structure. In addition, the air that leaves the ventilation system of the house passes freely through the space of the attic and thereby serves as an additional source of heating in the cold season.

The attic is not only a makeshift warehouse, but also serves as a kind of air cushion between the roof and residential floors. In this case, interior decoration is not carried out and there are no additional costs for building materials. But how to equip and improve the attic in a private house, first of all, is up to the owner to decide.

The main differences between the attic and the attic

And yet, what is the difference between an attic and an attic? Let's make a comparison.

1. The attic floor is intended for permanent residence. Attic space - serves as a technical room.
2. The attic can be either warm or cold. The attic requires good, high-quality insulation and ventilation.
3. The design features of the attic space are diverse and do not have clearly defined parameters, and for a residential attic tier, the maximum wall height should not exceed 1.5 meters
4. The financial resources spent on equipping the attic are many times higher than the cost of equipping the attic.
5. requires the installation of special windows. For the attic, one or two small, even deaf windows are enough.
6. Documentary aspects. The total area of ​​a residential building, in contrast to the attic, does not include the square meters of the attic.

As you can see, almost all of the differences are based on the functionality and characteristics of the premises.

What's better?

There is no definite answer to the question of which roofing room is better. If the developer is satisfied with the living area of ​​the first floor and the financial situation leaves much to be desired - the attic floor must be abandoned. Any type of attic is fine and can be converted into living rooms over time. For those who need extra square meters, they want something unusual and creative - the attic floor will come in handy. The only drawback, perhaps, will be the construction of a garage or a shed on the backyard for old things.
