Design for access and mobility general mobility general requirements for access – New building work
AS1428.1 provides building designers, practitioners, regulators, and owners with the minimum design requirements for new building work to enable access for people with disabilities.
This new standard replaces the 2009 version and provides further details and clarifications, including more examples of handrail terminations for stairs and ramps, as well as additional room layouts for accessible sanitary facilities.
These are some of the changes for AS1428.1-2009 to AS1428.1-2021:
Timber boards – installation requirements
Threshold ramps – a total length of 300mm from the face of the door

Handrail heights are allowed to vary on landings and include a 10mm construction tolerance
Handrail diameters are increased to 52mm to accommodate construction methods
Door reveals are required to have a max depth of 300mm
Viewing panel sizes in doors are defined
Grabrails can have a greater variation in height of 800-820mm
Backrest requirements and dimensions have greater details
Basins are allowed to intrude into shower circulation spaces as well as toilet pan circulation spaces
Fold down shower seats are implicitly referenced as acceptable to overlap in the toilet pan circulation space (not in fold up position).

Heights of shower outlets have a greater range
