3 It represents good practice and is not adefinitive interpretation of current building regulations. The guide aims to anticipate many of the problems experienced bywheelchair users, although it is acknowledged that in some situationspractical and financial factors may restrict options. It is important thatarchitects, surveyors and occupational therapists are involved in theplanning and alteration of properties for wheelchair users from the initialstages. If alterations are planned to a disabled person's home, it is alsoparticularly important that their views, and the views of their carers, areincluded as part of the planning 14/8/06 5:43 pm Page 3 Design guide for wheelchair accessible housing41500mm635mmWheelchair mobility Turning spaceFor standard wheelchairs to turn through 360 degrees the space requiredis 1500mm x 1500mmThe overall width of a wheelchair is approximately 635mm when it isunoccupied.

4 Additional space is needed at each side of the chair toenable the user to propel it are many different types and sizes of manual and electricwheelchairs, some of which are modified and will take up greater spacethan already described, for example those with reclining backrests orelevating 1. wheelchair turning circleOT 14/8/06 5:43 pm Page 4 Design guide for wheelchair accessible housing5 Access and Entrance requirementsWhere possible, there should be level access to the property. For ramped access, the gradient should ideally not be steeper than 1 gradient of up to 1:12 is acceptable only if there is no alternative. The clear width of the ramp should be a minimum of , steep ramps should be avoided because they can cause thewheelchair to overbalance or the wheelchair user/assistant to lose controlof the speed at which the wheelchair descends.

5 It is also more difficult forwheelchair users to propel themselves up the ramp or for the assistant topush there is no alternative other than the construction of a long ramp , levelresting areas must be inserted where the wheelchair user can areas must be at least the width of the ramp and a minimum of1200mm long. They must be situated every five metres for 1:12 gradient,every 10 metres for 1:15 gradient, and every 18m for 1:20 gradient. There should be a platform directly outside the front door measuring1500mm x 1500mm to clear any door swing. The platform should extend300mm to the side from where the door swings. There should be a level area of 1500 x 1000mm at the foot of the the door opens outwards the platform will need to be increased by thewidth of the door.

6 This is particularly important in ramps running parallel tothe building, at 90 degrees to the platforms should have slight falls away from the building to preventrainwater from collecting. The cross-fall gradient should not exceed 1:50. 2OT 14/8/06 5:43 pm Page 5 Design guide for wheelchair accessible housing6A channel drain with grid may be provided across entrance ramp and platform should have a raised kerb at a minimum heightof 100mm to prevent the wheelchair slipping over the edge. If the kerb isformed as a continuous concrete upstand, spaces or holes should bemade at intervals to allow rainwater to run off ramp or platform. Theupstand should be differentiated from the ramp by colour handrail alongside the ramp will be at a vertical height of 900mm tothe top of the rail and extend horizontally for 300mm past the end of theramp.

7 An additional rail at a height of 550mm is essential to ensure wheelchairsafety. The rails should have a positive stop, preferably turned down andterminated at ground (if door opens inwards)5m (maximum 1:12)10m (maximum 1:15)18m (maximum 1:20) curb 100mm1000mm (mimimum)2400mm (if door opens outwards)900mm900mm550mmDiagram 2. RampingOT 14/8/06 5:43 pm Page 6 Design guide for wheelchair accessible housing7 The ramp should be slip-resistant and made of concrete with a lightlyroughened surface to aid grip. A dimpled surface is preferable. Anyinspection or access covers must be flush with the finished front gate should have a clear opening width of 850mm minimumwith no steps from the pavement to negotiate. Gates should not bespring-loaded. The latch should be large and easy to operate, should be provided at the top and bottom of each flight of patio area should be provided outside secondary external doors and,where practical, it should be linked to a main path to provide a safemeans of escape for a wheelchair user in an emergency.

8 The patio shouldbe a minimum of 3m x 3m. Wherever possible, the patio area should be level and adjacent to thedoor to provide safe secondary access and a sitting out area. Wherepossible, the patio should be level with adjacent garden. Where a significant change of level is unavoidable, a raised 100mm kerbmust be provided where there is a risk of the wheelchair rolling. OT 14/8/06 5:43 pm Page 7 Design guide for wheelchair accessible General requirementsAll doors should be suitable for pulls or grab rails, needed to assistopening and closing, and for the subsequent fitting of other door furniture. All doors should swing beyond 90 degrees, with door stops providedwhere required to protect walls/other doors. Space must be provided to manoeuvre the wheelchair past the plates should be 350mm high and should be fitted to the bottom ofthe door to prevent damage by a wheelchair .

9 Kick plates can be made ofmetal to order, or ordered ready furniture should contrast in colour with the Entrance doorsEntrance doors should be 1000mm door set. There should be a minimumclear opening width of 840mm. Ideally the door opening should be900mm should be a clear space of a minimum of 300mm between theopening edge of the door and nearest obstruction to the side, a of external doors should be flush. If a threshold is unavoidableit should be no more than 15mm high and bevelled to prevent thewheelchair from jarring. Metal thresholds, which have compressible rubberstrips, are most suitable. 3OT 14/8/06 5:43 pm Page 8 Design guide for wheelchair accessible housing9 There should be a gap of at least 380mm between the top of the doorand the ceiling so a suitable door-opening device, for example anelectronically operated door opener/closer, can be installed if required.

10 Fully glazed doors are not appropriate. If a door with a vision panel isused it should have a zone of visibility between 500mm and 1500mmabove the floorThe door furniture selected should offer maximum security while beingeasy to operate by people with limited control or strength in their hands. The door handle should be a lever type and easy to operate, positionedat height of 1000mmThe door must be suitable for use with electric door release to allow futurefitting of door entry system. 900mm300mmDiagram 3. DoorwayOT 14/8/06 5:43 pm Page 9 Design guide for wheelchair accessible housing10If a door entry system is installed it should be located at the latch side ofdoor with activation pad within 200mm of the doorframe, at a height ofbetween 750mm and doorbell should be positioned at a height of 1000mm.
