If you’re also considering updates like patio extensions, carports, or even linking structures with shade, we can help you plan it all. We work closely with our expert Perth patio builders to bring everything together into one smooth, stylish outdoor layout.
And unlike some flat-pack or kit homes, these granny flat modular homes don’t feel like temporary boxes—they feel like real homes. Because that’s what they are.

FAQs – Granny Flats Perth
Can I rent out a granny flat in Perth legally?
Yes! WA regulations now allow homeowners to rent out Perth granny flats to non-family members, as long as they meet local council requirements. We’ll help ensure your design ticks all the boxes for legal rentals.
How much space do I need to build a granny flat?
Most councils allow up to 70m² for a granny flat modular home, excluding patios and carports. We’ll assess your block and help you make the most of the space you’ve got—even on narrow or sloped lots.
Do I need to prepare the site before installation?
We handle the entire process, including site prep. Before installing your granny flat modular building, we’ll level the ground (if needed), pour footings, and make sure all services can be connected properly.
How long does it take to build a modular granny flat in Perth?
Timeframes vary based on design and council approval, but modular builds are typically much faster than traditional construction. Most modular granny flats in Perth are ready to move into within a few months from approval.
