BSD opinion on accessibility within a dwelling via a future stair lift under a SCOTTISH TYPE APPROVAL submission

The Opinion of the Building Standards Division The intent of guidance Clause 4.2.9 is to provide a suitable space for parking a future stair lift, with the seat in a folded position, clear of a stair. Irrespective of whether a stair lift is parked adjacent to the top or bottom of a stair, a clear unobstructed space having dimensions of 700mm x 400mm is required to facilitate parking. 
The guidance also intends that a suitable space (200mm x 400mm) is provided to enable transfer to and from the stair lift. This space is generally provided adjacent to the top nosing of a stair. However, the proposals indicate a larger transfer area adjacent to the bottom riser of the stairs, which will accommodate a hinged rail extension and allow lifts to terminate clear of the stairs to enable passenger transfer. 
It is considered that the alternative proposals submitted indicate adequate space to accommodate both the parking of the lift at the top of the stair and also the required transfer space at the bottom.
