Like many parts of Australia, the ACT is facing a housing crisis, with demand outpacing supply and affordability becoming a growing concern. As the cost of living rises and housing options become more limited, secondary dwelling, or secondary residence as they are known in the ACT, offer a smart way to maximise existing space, provide additional housing, and create a more adaptable home for changing family needs.

Building a secondary residence—often called a granny flat—is an excellent way to:

• Keep family members close while ensuring independence.
• Generate extra income through rental opportunities.
• Provide flexible, affordable housing options in your community.
• Maximise the potential of your existing block.
• Adapt to changing household needs, such as ageing parents or young adults seeking their own space.
