What would constitute a localised obstruction in the shaded area shown in Diagrams 1.2, 2.3 and 3.3?
Localised obstructions means any element that might impede the ability of a wheelchair user or person using mobility aids to turn easily through a door opening or around a corner. Localised obstructions are fixed items such as a protruding radiator or a wall-mounted fire hydrant. Skirtings and architraves can be ignored when measuring clear widths.
The grey shaded areas in diagrams should be free of wall nibs, services or any protruding elements, however, a localised obstruction is only problematic if it is in the likely path of travel of someone entering or leaving a room or turning a corner. Where grey areas are indicated to both sides of a door this assumes that the door can be approached from two directions – if a door can only be approached from one direction then a clear zone on the other side of the door is not required (e.g. at the end of a corridor).
