Step 1: Measure the Usable Area
- Measure between interior walls.
- Ignore obstacles.
- For attics: only include areas higher than 1.50 meters and with a minimum area of 4m2.
Example: Total usable area = 160m2
Step 2: Measure Other Indoor Spaces
- Identify non-living areas.
- For attics: measure above 1.50m, exclude below 1.50 meters.
- Include basements with a height of 2 meters and no daylight.
Example: Total indoor space = 35m2.
Step 3: Calculate Living Area
- Subtract indoor space from usable area.
Example: Living area = 160m2 - 35m2 = 125m2.
Other: Building-Related Outdoor Space
- Measure balconies, rooftop terraces, etc.
- Note: Garden area is measured and entered separately.
With these steps, you can quickly and easily determine the net living area of your house. Remember: only include spaces with a clear residential function.
