Questions people ask
What is a secondary dwelling?
It is the term Queensland planning rules use for a granny flat: a second dwelling on the same lot, used with and secondary to the main dwelling.
Do I need approval for a granny flat in Queensland?
Usually, yes. Whether you need planning approval, a building approval or both depends on your council and your design. We help you check before you order.
Does a unit on a trailer need approval?
It depends on your council and how the unit is installed. A unit that stays on its trailer base is often treated as a movable dwelling and may not need building approval. A permanently installed unit usually does. Always confirm with your local council.
How do you help with approvals?
We walk you through what your block needs before you order. Ask us for the floor plan and specifications to take to your council.
