Specialist Disability Accommodation (SDA) is the term used for the provision of accommodation under the National Disability Insurance Scheme (NDIS), meant for individuals with profound functional limitation or very high support needs. Out of all the design categories of SDA, the High Physical Support (HPS) provides maximum accessibility and support. The high physical support SDA homes have been built specially for those individuals who need high physical assistance, specialised equipment and technologies.
As opposed to the usual accessible houses, there are some additional design aspects provided within the HPS category which make these places safer and more independent for living. This blog explores the key design features of High Physical Support SDA homes and how they help residents live more independently and confidently.

If you know What is an SDA home, you know there are multiple categories under it. A High Physical Support SDA dwelling falls in the category of accommodations that have been specially created for individuals who have significant physical disabilities and extensive support needs. This type of dwelling allows the integration of assistive technology and promotes independence and safety.
The HPS SDA fund is normally available to NDIS participants who experience significant physical impairments and require a high level of daily assistance. These individuals may be dependent on mobility aids, have support workers regularly assist them, or may need specific aids to perform routine tasks. The qualification for receiving funds is assessed by the NDIS.
Although accessible housing may be able to offer basic accessibility via wheelchair and enhanced mobility, it typically fails to incorporate the necessary elements that participants with challenging needs require.
Typical Perth SDA homes lack the means to accommodate ceiling hoists, power supplies, automatic environmental control systems, or room for support workers and equipment. Such obstacles may continue to hinder participants from achieving their desired level of independence and security.
