Hybrid Housing Scenarios
Scenario 1
Downsizers ageing in place
An older couple could live in a smaller main dwelling and either rent out the two auxiliary suites for income or have family and carers nearby. This allows people to remain in their community longer and reduces pressure on aged-care facilities.
Scenario 2
First-home buyer affordability model
A first-home buyer could purchase the property, live in the main dwelling, and rent the two auxiliary suites to help meet mortgage repayments. This supports home ownership and housing supply without the building operating like short-term or rooming accommodation.
Scenario 3
Multigenerational Living
The main dwelling may be occupied by a family, with auxiliary suites used by grandparents or adult children. This arrangement supports multigenerational living by providing independent, self-contained spaces while maintaining close family connections. It enables shared care arrangements—such as grandparents assisting with childcare or families supporting ageing parents—while preserving privacy and reducing reliance on institutional care.
Scenario 4
Student accommodation
A couple or small family could live in the main dwelling, with one auxiliary suite rented to a university student and the other to an apprentice or trainee on separate agreements. This creates safe, small-scale rental supply without the intensity or shared-facility model of rooming accommodation.
Scenario 5
Blended or separated family living
A separated parent could live in the main dwelling, an older child or co-parent could live in one auxiliary suite, and another suite could be rented to a tenant or occupied by a grandparent. This arrangement supports shared care, privacy, and family stability.
Scenario 6
Multi Tenancy with unrelated parties
The main dwelling could either be leased to a single family or occupied by the owner, while each auxiliary suite is rented separately to unrelated individuals or couples—such as a nurse or a teacher—under individual leases. This arrangement results in three independent households within one built form, with each occupant living in a fully self-contained space. As such, the use remains residential and independent in nature, clearly differing from a standard dwelling house, while also not constituting rooming accommodation, as it is limited to three self-contained homes rather than multiple rooms with shared facilities.
Scenario 7
Adult children transitioning
Parents could live in the main dwelling, with one auxiliary suite occupied by an adult child returning from university or starting work, while the second suite is rented to a couple or single tenant. It gives younger adults independence without losing connection to family support.
Scenario 8
Disaster or displacement resilience
A family could live in the main dwelling while one or both auxiliary suites house relatives or friends displaced by flood, fire, renovation, or another housing disruption. Hybrid housing can respond quickly to changing residential needs while still functioning as permanent housing.
Scenario 9
Investment Model with Flexability
An investor could lease the main dwelling and both auxiliary suites as three separate tenancies. Each suite operates as a self-contained living space, allowing for a mix of long-term and shorter-term rental arrangements. This model increases housing supply without relying on traditional rooming accommodation or short-term visitor use.
Scenario 10
Disability or support-based living
A person with disability could live in the main dwelling with family, while a support worker, or close relative occupies one auxiliary suite and the second suite is rented or used by another family member. Separate self-contained spaces improve dignity, privacy, and flexible care arrangements.
Scenario 11
Key worker housing
In suburban, regional, or rural areas, the main dwelling could house an owner or family while the two auxiliary suites accommodate key workers such as teachers, paramedics, or tradespeople on medium- or long-term arrangements. This helps address housing shortages for essential workers without becoming short-term visitor accommodation.
Scenario 12
Large Family with Auxiliary Income/Support
A large family could occupy the main dwelling, which may contain four or more bedrooms depending on design needs. At the extreme end of the scale, a family with up to 10 children could utilise the main dwelling as a single household, while the two auxiliary suites may be used to generate additional income through rental or to accommodate extended family members for support. This demonstrates the flexibility of the model to support higher-occupancy family living, while still providing independent, self-contained accommodation within the same development, consistent with residential use in low-density zones. The floor area in this scenario would likely exceed 300m2 and there would likely be more than 12 occupants.
