Access area requirements at entrances

An accessible entrance should – (a) be readily apparent (e.g. distinguishable, through suitable visual contrast from that of the adjacent elements of the building); and (b) have an access area – (i) that is level. However, where the access area contains a crossfall, it should be not steeper than 1 in 40; (ii) with a surface that is firm; (iii) with an unobstructed size of not less than 1500 mm by 1500 mm in front of the accessible entrance; and (iv) that is at, or about, the level of the floor of the entrance.
