Gently sloping
The building regulations set out legal requirements for specific aspects of building design and construction. A series of approved documents provide general guidance about how different aspects of building design and construction can comply with the building regulations.
Approved document M provides guidance for satisfying Part M of the building regulations: Access to and use of buildings, which requires the inclusive provision of ease of access to, and circulation within, buildings, together with requirements for facilities for people with disabilities.
Approved document M, Volume 1: Dwellings (2015 edition incorporating 2016 amendments) defines ‘gently sloping’ as a:
| Gradient between 1:60 to 1:20. |
That is between 0.95 degrees and 2.86 degrees.
The approved document describes situations in which surfaces should be flat or gently sloping or (or sometimes ramped or where unavoidable, stepped), such as approach routes, parking spaces, drop off points, and certain paths in private outdoor spaces.
