How to calculate the surface area of a duplex flat in Luxembourg?

If you own or buy a duplex apartment in Luxembourg, it is important to know how to calculate its surface area. Knowing the surface area of your duplex is important for tax purposes and to help you determine its market value. In this blog, we will explain how to calculate the surface area of a duplex apartment in Luxembourg.

First of all, it is essential to understand what a duplex flat is. A duplex flat is a type of flat that is divided into two floors connected by an internal staircase. Both levels are considered living space and must be taken into account when calculating the floor area.

The most common method of calculating the area of a duplex is to measure the area of each floor and add them together. To measure each floor, do the following :

  • Measure the length and width of each floor with a tape measure. Make sure you measure the rooms accurately, taking into account corners and non-rectangular rooms.
  • Multiply the length and width to get the area of each floor in square meters. For example, if the floor is 8 meters long and 6 meters wide, the floor area is 48 square meters (8 m x 6 m).
  • Add the area of each floor to get the total area of the duplex. For example, if the first floor is 50 square meters and the second floor is 40 square meters, the total area of the maisonette is 90 square meters.

It is important to note that the living area of a maisonette does not include non-habitable areas such as staircases, lobbies and wardrobes. It is also important to remember that the living area of a semi-detached property may vary depending on the method of calculation used and the local standards of measurement.

In conclusion, calculating the living area of a duplex apartment in Luxembourg can be done by measuring the area of each floor and adding them together. By taking into account considerations such as non-habitable areas and local measurement standards, you can accurately determine the surface area of your duplex apartment. This can help you assess its market value and meet your tax obligations.
