Do you want to build? Then you must have heard the term built-up area at least at the building office. What is it actually about? Simply put, the built-up area of a plot of land is the sum of all the built-up areas of the individual buildings.
Built-up area of the building according to the Building Act
In connection with a building it is necessary to determine and define its area, the term built-up area is the most common, but we can also encounter floor area.
As mentioned above, the built-up area is the sum of all built-up areas of individual buildings. It is the area bounded by the orthogonal projections of the outer face of the external face of the perimeter structures of all above-ground and underground floors into the horizontal plane. The areas of loggias and bay windows are included. For semi-enclosed buildings (without some external walls), the built-up area is defined by the envelope lines drawn through the outer faces of the vertical structures to the horizontal plane.

The built-up area of a plot of land is a monitored figure, which regulates the density of development in a particular area by the parent documentation. An example of such documentation is the current municipal zoning plan, if issued. Otherwise, if it is not, the provisions of Decree No. 501/2006 Coll. on General Requirements for the Use of Land are used to determine the maximum percentage of land built up with buildings.
A so-called buildability coefficient is set, which is usually between 25% and 40% of the total land area. It can also be referred to as the proportion of the built-up area.
Did you know that the building code also limits the area of the house and the size of the house?
