Hidden
The following spaces do not count: living room, bathroom, corridor, kitchen, garage, storage loft and storage space.
Is the attic used as a sleeping or hobby room? Then it counts.
This is the sum of:
- all floors of the house, without the storage loft (small part directly underneath the roof often used for storage (Dutch: Vliering))
- an attached storage room or garage
If the house has separate outbuildings, enter the joint floor area of all separate outbuildings.
This is the sum of:
- all floors of the home
- an attached storage room or garage
How do I calculate this?
- Multiply the floor area of each floor by the height. The standard height of a floor for many homes is 2.5 meters
- the volume of a floor under a sloping roof is often (just over) half of the floor area times the highest point
