How to calculate the area of ​​an apartment

The legislation in building law in Bulgaria is multi-layered, complex and almost incomprehensible to ordinary citizens.

You can often find housing listings with a specified squaring that adds the squaring of the common parts of the entire building.

Over the years, the area of housing has been determined in different ways, which means that according to a notarial deed for the same housing sold in different years, different squares can be written.

Until 1991, in property documents, the built-up area was calculated as the sum of the quadrature of all premises, the thickness of the walls + 1/4 of the area of balconies, loggias, terraces.

After 1991, it is already calculated as follows: the square of housing includes the full square of balconies, loggias and terraces.

Below are a few simple rules that we can use to correctly calculate the built-up area of each individual object in a building - an apartment, a studio, an office, a store, a garage, and more. Any such object has a precisely built-up built-up area, which is described in the architectural project.

The built-up area is determined from the surrounding walls, according to the following simple rules:

  • The area of the apartment (or other independent object), located on more than one floor, is the sum of the built-up area of its individual floors, including the stair quadrature in them;
  • In the external enclosing walls with holes, 1/2 of the thickness enters the built-up area, and the other 1/2 enters the common parts of the building;
  • External enclosing walls without openings (windows or balcony doors) in the built-up area of the apartment include the entire thickness of the wall;
  • For external surrounding walls with openings, the same rules apply for external walls without openings. The built-up area includes 1/2 of the thickness, and the other 1/2 is included in the common parts of the building;
  • In the internal surrounding walls to the common property (corridor, elevator, stairs, etc.), the built-up area includes 1/2 of the thickness, and the other 1/2 of the common parts of the building;
  • The entire area of terraces, balconies and loggias is added to the built-up area according to their external structural outlines;

Internal surrounding walls adjoining an adjacent independent object include 1/2 of the thickness in the built-up area, and the other 1/2 is included in the area of the neighboring property.

This is exactly the area that you actually buy and will own and this will be described in your notarial deed. This is the way in which you yourself can calculate the quadrature and it is this quadrature that will be indicated in the notarial deed.

Each independent object in a building, by law, has a percentage of ideal parts from the total square.

The notarial deed records the built-up area of the object and the percentage of ideal parts of the total. Common parts include and construction, foundations, piping, HVAC vertical pipes, plumbing and electrical, installations.

If, according to a notarial deed, for example, you have 7% of ideal parts from 100 sq.m. common area, it does not mean that you have 7 sq.m. area. This means that you own every square meter of the total area of the building, every part of the structure, respectively every linear meter of all installations in the building with a corresponding percentage - 7%, along with all other owners. It is impossible to pinpoint and separate exactly what your 7% of common parts are, where they are located, or to enclose them approximately. This is the law.

When buying an apartment, you legally acquire the corresponding percentage of ideal parts of the total area. You cannot buy only the ideal parts from the common ones, and the builder also cannot sell you an apartment without selling the common parts.

We hope that this article was useful and now it has become clear what exactly you are purchasing or already have, and what square is real, and not with common parts.
Legal construction is one in which the laws and regulations associated with construction are not violated. It must be carried out in accordance with the issued building book, which are necessary, and with materials of appropriate quality.
