Why Does Square Metre Calculation Matter?
Gross Area vs Net Area
In Turkey, title deeds are usually drawn up based on gross area. Gross area includes the outer walls, balcony, lift shaft and the share of common use areas. Net (usable) area is the actual living space measured from inner wall to inner wall, typically 15–20% smaller than the gross figure. The area you measure with this tool is always the net area.
