Floor Space Requirement
Space required by a staircase in plan view.
The floor space requirement of a staircase is derived from the storey height and the requirements of DIN 18065 or the applicable state building code. From this, going, rise, number of steps, usable stair width and run length are calculated. Where space is limited, compact solutions such as spiral stairs, quarter-turn stairs or space-saving stairs are available. Digital planning tools can help calculate the optimum stair layout.
