Metric Data 06 Wheelchair Accessible Dwelling

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.

Approach

 

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.
