Building land mask
A building land mask (sometimes incorrectly called a building mask ) is a narrow strip of land that cannot be built on independently, is part of the building land under planning law , lies between a building plot and the roadside and does not (yet) belong to the adjacent building plot in terms of ownership. Mostly, these are areas that, after reducing the original width of a previously parceled road or a change in the routing of a cadastral road closure measurement of a newly built road, remain as a building strip in front of sufficiently parceled building sites.
The area of a building land mask can only be used sensibly in the course of a consolidation by the owner of the adjacent building plot. For example, the State of Berlin sells such building land masks to residents at 50% of the standard land value of building land.
If the property is merged with the building plot after the purchase, it is no longer a building land mask, but usually the area then has the same quality and the same land value as the plot from which the purchase was made.
