Granny Flats in Perth

Independent living for family, guests or rental income — built on the land you already own.

A Second Home in Your Own Backyard

A granny flat is one of the most practical ways to add flexibility and value to a Perth property. It can house ageing parents or older kids, accommodate guests, or generate rental income.

Our most recent granny flat was approximately 68m² and was completed in ten weeks from earthworks through to handover, including a full kitchen, bathroom, bedroom and living area.

We handle the build end to end so you have a single team responsible for the site, the trades and the finish.

WHAT'S INVOLVED

✔  Ancillary dwellings up to 70m²
✔  Earthworks, slab and full structural build
✔  Kitchen, bathroom and laundry fit-out
✔  Independent living and bedroom areas
✔  Site services and connections
✔  Fast, tightly managed build programs

TESTIMONIALS

What Our Clients Say

I was kept informed during every stage of my extension. Each stage was also completed on time and as per the advice given to me by the supervisors Jack and Kyle. Any query or concern that I had was dealt with promptly, professionally and in (non-tradesman) easy to understand, customer friendly language. I found every person with whom I dealt to be courteous, friendly and readily approachable. A real credit to the company and ideal example to other builder (that I have used in the past) as to how to manage a building or renovation job. I would not hesitate to recommend Perth Extensions to anyone considering undertaking a home renovation, extension or refurbishment to utilize this excellent company for that purpose. I have in fact already recommended their services to other friend who are considering a similar home extension project as mine. A big thumbs up and very grateful thank you to the whole team.

Camillo, WA • Home Extension

Jack and the team produced an excellent result on the original wall removal job and I also contracted them for the associated bathroom renovation. Very professional, friendly and punctual and was always available to answer any queries. Jack also went beyond the original scope to help fix up some other jobs that came up throughout the project. Would definitely recommend
