If a route of travel exists underneath a staircase, you must ensure that a person can’t accidentally bump into the underside of the stairs.

Space underneath the stairs should be at least 2,030 mm high from the finished walking surface. If this is not possible, consider installing architectural detailing, plants or guardrails that can be detected by people who use long canes or guide dogs. This will help prevent accidental access to the underside of the stairs.
