Residential extension to a residential building: how to design and legalize

An extension to the house is the best option for increasing living space. Projects of such buildings are striking in variety, but you can draw up an individual scheme with which you can construct the planned object. However, such a premises still needs to be registered. Further, the article will describe how to properly design and build a residential extension to a private house.

Main types

An extension is any object that has a direct connection with the main (residential) building. However, there are some classifications, thanks to which it is possible to determine which project will have to be compiled in order to collect the necessary documents to legitimize it. Capital extensions include residential construction projects that increase the area of ​​the house. This can be, for example, additional rooms, for the construction of which you will have to try, since this work is equivalent to the construction of a small house. In this case, the foundation, walls and roof of the building will need to be insulated and the building must be provided with high-quality waterproofing to prevent dampness in the living room.

In turn, non-capital (lightweight) extensions include:

• shop windows
• stairs
• canopies;
• terraces or balconies;
• different protrusions, etc.

For the construction of such simple buildings will have to make small changes to the main architectural project. To issue a non-residential extension to a residential building is a simple matter, since in this case special permits will not be required. The construction process can begin after making minor amendments to the technical plan. In addition, non-residential extensions are also considered:

1. Garages, if they are built on the site of the partnership gardeners.
2. Auxiliary extensions - sheds, storage rooms and other non-residential objects.
3. Structures that do not affect the main communications and structures during the work process.

Registration of non-capital structure

In order to issue an extension of a lightweight type to a residential building, the owner needs to collect the necessary documentation and take it to the local BTI (technical inventory bureau). The specified authority draws up an application for amending the design documentation. Then the BTI workers go to the site where the extension was built, and a special acceptance committee draws up an act whose purpose is to confirm that the building complies with all standards. However, it is recommended to preliminarily legalize the construction of the facility, since BTI employees may not give permission to carry out these works. If everything is successful, the owner of the site is given back the documents as amended.

It is difficult not only to legalize the capital extension, but also to erect it in accordance with all the requirements, so the construction process will be considered in detail. For such an object, the project documentation should be prepared by a specialist, since the slightest mistake can spoil the drawing, and because of any flaw, the commission will not issue permission to build the extension.

The device of the column foundation

When drafting and purchasing materials, it should be noted that it is better to build a residential extension to a wooden house on the specified foundation. The tape base is often built of brick or concrete, but for economy it is recommended to combine both materials. This option is more often used for the construction of a capital extension, since it will be easier to clad the underground with heat-insulating material. To organize a columnar foundation, you need to do the following:

1. Using a rope and pegs, mark the area so that the posts are located every 1.5 m.
2. Dig pits 50 x 50 cm in size for supports. The depth of each pit should be 50-60 cm.
3. Fill the bottom of the pits with a sand cushion 10–12 cm thick, and then compact the layer by hand tamping.
4. Strengthen additional pits with rubble or broken bricks.
5. Put waterproofing material (for example, roofing material) in each recess.
6. If it is planned to build brick pillars, it is desirable to process the bottom with a layer of coarse cement mortar, after hardening of which it is necessary to carry out brickwork. In turn, in order to build a residential extension to a residential building on concrete or concrete concrete supports, it will be necessary to first install the reinforcing structure and wooden formwork at the height of the planned pillar at the bottom of the pits. In this case, it is necessary to sheathe the inside of the formwork with a roofing material and fix the waterproofing on top of it.
7. Fill prepared pits with concrete. To get a reliable foundation for a residential extension to a residential building, each layer must be poured after the previous one has completely dried.
8. Spray the protruding parts of the pillars daily with water until they completely harden.
9. Dismantle the formwork and sheathe the posts with roofing material, which must be glued to the bitumen mastic (primer).
10. Backfill into the gap formed between the soil and solidified supports. At the same time, every 10-15 cm of the filled earth with rubble must be rammed.
11. Lay on each pillar several rolls of roofing material for waterproofing the bars, which will be laid on top of the pillars of the columnar foundation.

But if you need to attach a stone (for example, from a cinder block or aerated concrete) residential extension to a brick house, in this case they make a tape base.

The device of the floor on wooden beams

Lumber should have a cross section of at least 15 x 10 cm. It is not recommended to save on beams, since not only the strength of the floor will depend on them, but also the reliability of the entire building. The technique for mounting beams is quite simple:

1. Lay the material on supports with ruberoid substrate.
2. Fix the beams to the posts with anchor bolts, angles or other fasteners.

The name of the finished structure is grillage. In this case, you will have to make a frame residential extension to the residential building. However, the beams must first be treated with a flame retardant and antiseptic to increase their technical characteristics.

Walling

If a quality grillage of beams was organized, then in this case the best choice for the construction of the extension is frame technology. To build a building, you need to follow the following methodology:

1. Build and secure the frame to the grillage. The bars need to be fixed to the coating beams separately, but it is more convenient to assemble the structure in a horizontal position on an even area. As a result, the frame in the finished form must be installed on the grillage.
2. Make vertical markings on the frame in order to further fix it to the wall of the main building.
3. Connect the bars with metal corners.
4. Install the annex frame and sheathe it with boards, plywood, chipboard or OSB from the outside.
5. Attach the upper horizontal beam, which is placed along the house, to the main wall with wood anchors, self-tapping screws or metal corners.
6. Treat the structure with stain or varnish.

To build a brick or stone residential extension to a wooden house, you need to make a hole in the wall of the main building and insert reinforcement with a transverse stopper in it, the purpose of which is to hold the part. This iron element will have to be installed during the construction of the structure every 2-3 rows.

Overlap of an extension

After the construction of the walls you need to build a ceiling. To perform these works, beams are needed that are installed every 60 cm on the upper part of the frame, and then are fixed with corners. If you need to make the roof of a brick extension, in this case, it is enough to immobilize the lumber into the concrete belt. However, their edges must first be wrapped with roofing material.

The next step is to sheathe the beams with thick plywood or boards. As a result, it is necessary to carry out roofing, install windows and doors, and then only begin registration of the erected object. The main thing is that it conforms to all technical standards.

Making an extension: general rules

There are two methods to build an object:

• officially;
• arbitrarily.

In the first option, the construction of the extension is carried out legally, therefore, such construction should begin with the collection of the required documentation to legitimize the premises. In addition, it will be necessary to coordinate work with the supervising authorities, the result of which will be the reconstruction of the building or a change in its area.

With the unauthorized method of building the extension, the object is first built, and then officially registered. But in any case, it will be necessary to legitimize the additional structure, since it violates the design of the main building to which it is attached.

What are the requirements for an extension?

1. The building is allowed to be located only on land that belongs to the owner.
2. The building should be safe for residents and their property.
3. The extension is required to meet all urban planning standards and requirements for structures of this type.
4. The building should not interfere with other citizens (for example, obscure their plots).
5. The structure must be erected so that the interests of municipal authorities are not violated.

The process of formalizing a capital extension

First you need to collect the following documents:

1. Registration certificate and home ownership plan.
2. Written permission from other owners, if any.
3. Consent of neighbors (also in writing).
4. Capital extension project plan.
5. Documents for the plot and the house to be reconstructed.
6. Permission of utilities.
7. Cadastral plan of the land.

It is advisable that the project documentation be prepared by specialists, since any inaccuracy in the creation of the drawing will cause a failure. When all the required documents are collected, they must be referred to local authorities (the application is submitted to the architectural department). As a rule, a written response must be sent to the owner within a month. If permission is granted for an extension, the construction of this additional facility can be started to the residential building according to the design documentation.

Upon completion of the construction, the owner submits to the administration a completed application for acceptance of the facility. Then a special state commission is created to check the constructed building for compliance with the standards. If everything is normal, a conclusion is drawn up, which must be transmitted to the BTI. At the final stage, you will need to take the documentation (corrected data sheet) to the Federal Registration Service and pay the fee. So the property will be officially registered.

When the verdict, on the contrary, is negative, in this case, the construction of a residential extension to a private house will be considered illegal. More often, the owner receives a refusal due to such reasons:

• underground utilities are too close to the planned facility (the permissible distance is at least 2.5 m);
• during the construction process, the supporting elements of the main building may be affected;
• It is planned to build an extension of low-quality materials.

However, the applicant, having corrected the defects, may appeal the decision in court.

Unauthorized extension to a residential building: list of documents for legalizing

Some residents solve the problem of registering an object after completion of its construction. In order to draw up a finished capital extension, you will have to go through the whole process of legalization through the courts with the following documents:

1. Any official paper confirming that the applicant owns the land (for example, a contract of sale or inheritance).
2. Resolution from housing and communal services.
3. Consent from the neighbors (required if the house is designed for two owners) in writing, certified by a notary.
4. Documents from BTI on the main building to which the extension belongs.
5. Application from utilities (water utility, fire inspectorate, architectural bureau, etc.).
6. Detailed sketch, plan, drawing or drawing of an extension. The main thing is that the project should be properly designed.
7. Extracts from the house book.
8. A snapshot of the main building with an annex.

Without the necessary documentation, it will not be possible to officially formalize a previously erected object.

Registration of an unauthorized extension

After collecting the documents, you should contact the local administration, but it will most likely issue a refusal to complete the design. In this case, in order to legalize the extension to the apartment building, one must go to the district court with a package of official papers, to which an additional statement of claim must be attached. However, before this, it is necessary to turn to experts who have the right to conduct a technical examination at home, since the judicial authorities in any case will require an expert assessment.

If the court, having examined the documentation, decides that there are all legal grounds for registration, the case will be won. With a positive court decision, the owner needs to contact the administration. As a result, the landlord must pay a state duty (approximately 500 rubles) and register the object with BTI.

But the court does not always rule in favor of the applicant, who illegally built an extension. In this case, the illegal structure will have to be dismantled. In addition, the owner will not receive any monetary compensation, but, on the contrary, he can be fined.

Annex to the apartment building: legalization of the object

First you need to collect the necessary documents, namely:

• written consent from all residents;
• project documentation;
• floor plan;
• permission from the architecture committee.

The list may include other papers. In addition, an extension to a residential multi-apartment building can only be erected with the permission of the municipality. To get approval, you need to refer the documents to local authorities, which must issue a permit.

The main causes of failure are:

• proximity to communications;
• the windows of the apartment building overlook the city center;
• the building will interfere with others or spoil the appearance of the building.

Conclusion

The article described the process of how to quickly and efficiently build a residential extension to a residential building. However, it is not enough just to build this facility, since it still needs to be registered in order not to pay a fine for illegal construction. If you carefully study the information provided in this article, there should not be any problems with legalizing the premises, since all the nuances and features of this scrupulous bureaucratic process were considered.

The main thing is that the capital extension was built according to the project drawn up by a specialized organization, otherwise, due to a minor flaw, the commission may not issue a permit for construction. The object must be built of quality materials, taking into account all the rules and regulations. Only by completing them will it be possible to legitimize the extension. However, one should not forget about the costs, since only one payment for the examination will require about 20 thousand rubles.
