Built on trust. Driven by results.

We’re a Sydney team focused solely on granny flats , a specialist builder with streamlined processes that give our clients the best granny flat building experiences in Sydney.

We have decades of experience building Granny Flats in Sydney.

We launched Inhouse Granny Flats to do one thing exceptionally well: design and build secondary dwellings that look great, feel spacious and stand the test of time. Since 2008 we’ve refined our approvals process, tightened our trades network and invested in aftercare, because the build isn’t ‘done’ until you’re proud of it.
