 Access starts outside of the building, with the provision of reduced height kerb-cuts where wheelchair users may need to cross roads, and the provision of adequate wheelchair parking, which must provide extra space in order to allow wheelchair users to transfer directly from seat to chair.Some tension exists between access provisions for visually impaired pedestrians and wheelchair users and other mobility impaired pedestrians as textured paving, vital for visually impaired people to recognise the edge of features such as light-controlled crossings, is uncomfortable at best, and dangerous at worst, to those with mobility impairments.For access to public buildings, it is frequently necessary to adapt older buildings with features such as ramps or elevators in order to allow access by wheelchair users and other people with mobility impairments.
