Wheelchair access - circulation routes and doorway widths

It is important to ensure there is sufficient space to allow wheelchair users and others with limited mobility to safely enter the dwelling. The widths of hallways and door openings are important considerations in facilitating access and movement into, and between, rooms. These widths are interrelated and depend on the direction of approach of a wheelchair. For example the minimum width for a circulation route is 900mm which allows for a clear doorway opening of 750mm where the direction of approach is head-on. Alternatively a clear doorway opening width of 800mm will be required where the direction of approach is not head on. Further guidance is available in NI Building Regulations 'Technical Booklet R: Access to and use of buildings'.
