Surface measurement standards

The commercial market has its own rules. In order to define the object of lease, e.g. for the purpose of selling or rental, it is necessary to precisely determine the leasable areas of each respective building or premises on the basis of one of the available Polish or international commercial surface area measurement standards.

This portal was developed to provide details about area measurement and development standards according to Polish and international codes. If you are interested in more detailed discussion of the subject, please contact us directly.

The legislation in force does not emphasize any specific standard as mandatory, and therefore you can choose a standard that will help you obtain the most advantageous surface area in the given building at the given time, place and circumstances.

We are experts in surface area measurements and we know which standard or provision to use in order to optimize the area for the specific purpose. We calculate Add-on Factor for every standard that may allow determination of tenants' percentages in the building's add-on.

 Under the specific tabs, there is a brief presentation of the general rules applied under the particular standards; if you are interested in learning more details about area measurement standards and rules of standards selection for specific purposes, see our training proposal.
