SDA Building Types Explained: Apartments, Houses, and Group Homes

When exploring Specialist Disability Accommodation, most people focus on the four design categories — Improved Liveability, Fully Accessible, Robust, and High Physical Support. But there's another important dimension to consider: the building type.

What Are SDA Building Types?

SDA building types describe the physical structure and living arrangement of the dwelling. The NDIA recognises several building types, each with different SDA pricing and suitability for different participant needs.

Single-Resident Dwelling (Villa/House)

A standalone home designed for one SDA participant, with a separate room available for an onsite overnight assistant (OOA) if needed. This is the most independent living option and often the preferred choice for participants who value privacy and autonomy.

Advantages:

• Maximum privacy and independence

• Full control over the living environment

• Customisable design to suit individual needs

• Space for personalisation (gardens, outdoor areas)

Considerations:

• Higher SDA pricing (which can be positive for provider viability)

• May feel isolated for some participants

• Requires robust SIL support arrangements

Dual-Resident Dwelling

A dwelling designed for two SDA participants, each with their own bedroom and often their own bathroom, sharing communal living areas. This offers a balance between independence and social interaction.

Advantages:

• Social connection with a co-resident

• Shared communal spaces encourage interaction

• Often more cost-effective for providers

• Still offers significant personal space and privacy

Group Home (3-5 Residents)

A shared dwelling for three to five SDA participants, with individual bedrooms and shared living spaces. Group homes have been the traditional model for disability housing but are increasingly being supplemented by more independent options.

Advantages:

• Social environment with multiple residents

• Efficient use of shared support workers

• Often located in established community settings

Considerations:

• Less privacy and autonomy

• Shared decision-making about communal spaces

• May not suit participants who prefer independent living

Apartment

An SDA-compliant apartment within a larger residential building. Apartments can be single or dual-resident and are typically located in urban areas with proximity to public transport, shops, and community facilities.

Advantages:

• Urban location with access to amenities

• Community integration

• Often includes common building facilities (gym, gardens)

• Lower land costs may improve provider viability
