How to draw a stairwell

According to the BBMI Standard a stairwell larger than 4.0 square meter (m²) is not seen as living space. In order to calculate this correctly, our system needs to know which part of a room/surface represent a stairwell. Please note that if you don’t draw a stairwell with the exact dimensions in your Floorplanner project, the results of our calculation will differ from reality.   

Example:

Let’s say you need to draw an apartment that contains two levels: the ground floor and the first floor. There are stairs on the ground floor. This means that you need to draw a stairwell on the first floor.

How to:

Draw a surface on another surface in Floorplanner. Our system detects when two surfaces overlap and automatically subtracts the square meters accordingly.

1. Click on the Floor option in the left sidebar
2. Duplicate the ground floor
3. Select the draw tool in the left sidebar
4. Draw the surface on the place of the stair (according to the situation in real life)
5. Click on the settings option in the left sidebar
   
6. Give the surface the following name: Stairwell (or Trapgat in dutch)
7. Click back to settings
