Under commercial tenancy law, different optional methods are used to determine the area to be leased (see “Area Calculation Methods”). The calculation basis for determining floor area may vary depending on the location and the landlord. For example, currently about 85% of all office space in Munich is leased on a GFA basis.

To put it simply, the total floor area is measured from facade to facade to determine GFA. This way, construction areas, stairwells and shafts are included in the calculation.

Because this method of calculation gives us a larger area, rent per square meter is lower than that for the net floor area of the same space. In order to be able to compare rental cost, offers need to be considered on the basis of a uniform space definition.
