* The “Bruto Vloer Oppervlak” (Gross Floor Area) (“BVO”) of a building is the area measured at floor level along the exterior walls. For multi-storey buildings, it is measured per floor, including the m2 BVO of the covered building-related outdoor space, which is not or only partially enclosed and therefore has no fixed exterior boundary. The area of the space is equal to the vertical projection of the enclosed building section, regardless of the floor construction or method of surfacing.
