How does the NDIS consider the funding levels for your SDA housing cost requirements?

Improved Liveability SDA dwellings must also include one or more improved liveability design features suitable for the resident’s needs which may include elements such as luminance contrasts, improved wayfinding or lines of sight.


Intellectual and Cognitive – labelling, use of contextual cues, increased lines of sight, consistency in locations of fittings and fixtures, reduced lighting levels and other stimuli.

Fully accessible

The external doors and outdoor private areas must be accessible by wheelchair and the bathroom vanity and hand basin should be accessible in either a seated or standing position.

This includes secure windows, doors and external areas, high impact wall lining, fittings and fixtures such as blinds and door handles, soundproofing, and laminated glass.

The design should also include adequate space and safeguards to support the needs of residents with complex behaviours and provide areas of retreat for other residents and staff to avoid harm.

High physical support

High physical support housing is designed to incorporate a high level of physical access for people with extreme physical impairment. The tenants must require a very high level of physical support.
