In the vast universe of the property sector, concepts such as gross area, useful area and private gross area can be a confusing maze for many. Clarifying these terms can provide you with the data you need to make more informed decisions when buying or renting a property.

What is gross floor area?

The gross area encompasses all the internal space of a property. This includes not only the internal compartments, but also garages, balconies, terraces and storage areas, along with the building's communal spaces, such as corridors and staircases. The gross area includes all the internal and external areas of the property and should not be confused with the gross construction area.

The gross building area is the sum of all the built floor areas, both above and below ground. This includes living spaces, stairwells and areas where lifts are located. It is important to note that areas exclusively intended for below-ground car parking are not counted in the gross building area.

What is floor area?

According to the General Regulations for Urban Buildings, the useful area is the sum of the areas of all the rooms in the dwelling. It includes vestibules, interior circulation, sanitary facilities, storage, wall cupboards and compartments with a similar function. 

It is measured by the inside perimeter of the walls that limit the fire, excluding walls up to 30 cm, interior walls, partitions and ducts.

The measurement is taken from the inside perimeter of the walls that limit the fire, discounting encasements of up to 30 cm, interior walls, partitions and ducts.

In simple terms, the useful area excludes the interior walls, partitions and ducts of the property, making it smaller than the gross construction area.

Difference between useful area and private gross area

The Municipal Property Tax Code (CIMI) clarifies the private gross area, which should not be confused with the useful area. 

While both exclude balconies, terraces and garages, the gross private area covers covered and closed areas for exclusive use. It is measured by the "external perimeter and axes of the walls or other separating elements of the building or fraction, including closed balconies, basements and private attics with the same use as the building or fraction".

How do I calculate the floor area and other areas?

Calculating the useful area is simple: just multiply the length by the width of each room and add up all the useful areas to get the total useful area of the property. 

Detailed information about the different areas, including garages, terraces and balconies, is usually presented on the property plan during sales or rental processes.

Understanding these concepts is essential for making informed decisions in the property market, providing a clear view of the space available in a property.
