SDA design categories

The four kinds of SDA home, explained simply.

Specialist Disability Accommodation is built to one of four design categories set by the NDIS. The category reflects the level of support a home is designed to provide. Here's what each one means — without the jargon.

Category 01

Improved Liveability

For people who need a home that's easier to see, understand and move around.

Improved Liveability homes are designed with people who have sensory, intellectual or cognitive disability in mind. The focus is on making the home easy to understand and navigate, with good lighting, clear lines of sight and features that reduce confusion and risk.

Typically includes

  • Improved physical access throughout the home
  • Good natural light and clear contrast between surfaces
  • Easy-to-locate, easy-to-use fixtures and fittings
  • Layouts that are simple to navigate and remember
Category 02

Fully Accessible

For people with significant physical impairment who need a step-free home throughout.

Fully Accessible homes are designed for people who use a wheelchair or have significant physical impairment. Every part of the home is reachable and usable without steps, with the space and clearances needed to move freely.

Typically includes

  • Step-free entry and step-free access throughout
  • Wider doorways and generous circulation space
  • Accessible kitchen and bathroom with appropriate clearances
  • Reachable switches, controls and benches
Category 03

Robust

For people who need a very durable, safe home that reduces risk to themselves and others.

Robust homes are built to be resilient and low-maintenance. They're designed for people who may, at times, place high demands on their environment — so materials and fittings are tough, sturdy and safe, helping to reduce the risk of harm to the resident and to others, and the need for frequent repairs.

Typically includes

  • Impact-resistant walls, doors and fixtures
  • Secure, durable fittings that are hard to damage
  • Layouts that support safety and reduce risk
  • Considered acoustics and lines of sight
Category 04

High Physical Support

For people with very high support needs who rely on assistive technology and hands-on support.

High Physical Support homes are designed for people who need significant, often around-the-clock support. They include provision for assistive technology and a high level of physical accessibility, so support can be delivered safely and the resident can be as independent as possible.

Typically includes

  • Structural provision for ceiling hoists
  • Backup power for essential equipment
  • Heating and cooling suited to high needs
  • Space and reinforcement for assistive technology
  • Communication and emergency-call provisions

Which category is right? The SDA design category a participant is funded for is determined through the NDIS planning process, usually with input from health professionals — not by a builder. We can build to any of the four categories; we'll work to the category and requirements set out in your plan and by your SDA provider.
