Metric Data 06 – Wheelchair Accessible Dwelling
Approach, Entrance and Circulation
In Metric Data 06 we look at the approach to dwellings, entrance and circulation for a wheelchair accessible dwelling. This includes details such as requirements for ramps, car parking and corridors. These dimensions are useful when planning spaces and developing designs.
The following data is in accordance with the building regulations Part M for dwellings, category 3, Wheelchair user dwellings. Note there are different criteria for accessible dwellings and for visitable dwellings. These provisions only apply when a planning condition requires compliance for a wheelchair user dwelling. The provisions below are based on private dwellings with private access, and do not refer to communal entrances.

The approach to an accessible dwelling must be step free, and at the shallowest gradient that can be achieved.
The following elements must be considered:
- The approach route must have a minimum clear width of 1200mm
- Any localised obstruction does not occur opposite or close to a doorway or at any change of direction
- A passing or turning area with a minimum width and depth of 1500mm is provided at each end of the approach route
- A suitable ground surface is chosen for the approach route
- Suitable lighting is specified for the approach route to ensure the route is illuminated from dusk to dawn
- Any gate has a minimum clear opening width of 850mm, a minimum 300mm nib to the leading edge and 200mm nib to the following edge.
Ramps for wheelchair access
Any internal or external ramp must comply with the following points:
- Gradient between 1:20 and 1:15
- Length of flight must meet requirements of following graph (see below)
- Flights have a minimum clear width of 1200mm
- Landings are provided at the top and bottom of every flight
- A landing is provided at any change of direction and between individual flights
- Every landing is level and 1200mm min clear of any door swing
A parking space must enable a wheelchair user to get into and out of the vehicle from both sides, and access to the boot space. The parking space must meet the following requirements:
- A clearance zone of 1200mm to one side and the rear of a standard parking bay
- (In communal parking areas it must have 1200mm clear access zone both sides.)
- The parking space must be level and have a suitable ground surface for a wheelchair user.
A principal private entrance to an individual dwelling must comply with the following:
- There must be a level external landing with a minimum width and depth of 1500mm clear of any door swing.
- The landing must be covered to a minimum of 1200mm width and depth to offer protection
- The area must be sufficiently lit from dusk till dawn, either by a motion sensor or timer.
- There must be a clear turning circle of 1500mm inside the entrance area in front of the door.
- A minimum nib of 300mm must be provided to the leading edge of the door and must continue for 1800mm beyond it. A minimum nib of 150mm must be provided on the hinge side of the door.
- The door must have a minimum clear opening width of 850mm.
- The threshold is an accessible threshold.
- If there is a lobby the doors must be a minimum of 1500mm apart and a minimum of 1500mm between door swings.
- Any door entry controls must be mounted between 900-1000mm above finished ground level and a minimum of 300mm away from any external return corner.
Hall and door widths
Internal halls and doors must comply with the following requirements:
- A minimum clear width of 1050mm is required for every hall, approach or landing.
- If an approach to a door way is not head on, the minimum clear width is 1200mm.
- Any obstruction, such as a radiator, must be no longer than 2m in length and not occur close to a doorway or change in direction.
- Every door has a minimum clear opening width of 850mm.
- A minimum 300mm nib is provided to the leading edge of every door.
- A minimum 200mm nib is provided to the following edge of every door.
