There are two methods to structure a building:
- Rooms (with fixed walls)
- Room segments (typically based on movable walls)
One of the two methods or a mixture thereof is possible depending on the building structure or required flexibility (e.g., during the usage phase).
A room segment is the smallest indivisible element. A room comprises at least one or several adjacent room segments. A room segment is defined and created only once. Room segments are typically combined several times to rooms over the course of a building's lifecycle.
