A planted door stop can be easily repositioned to allow a door which opens inwards to be re-hung outwards without the need to change the door frame as a whole. Category 3 Wheelchair adaptable dwellings can, therefore, have inward opening doors, but must be capable of easy adaptation to provide the outward opening door required for Category 3 Wheelchair accessible dwellings. Flats typically need outward opening doors on the entry-level accessible WC.
