Granny Flats & Home Extensions & Renovations
Your Trusted Perth Builder

Granny Flats WA has long been Perth’s trusted builder for granny flats, home renovations and extensions. We have many years’ experience and know-how and we care about providing you with a beautiful finished product you can be proud of and enjoy.

Most people know that we build granny flats, but did you know that we also build renovations and extensions? From a small studio or office all the way to a complete home renovation to transform your 2 bedroom, 1 bathroom home into a 5 bedroom, 3 bathroom family home with pool and al fresco.

Of course we also build granny flats. We see them as micro homes in your backyard as we build them from concrete slab to finished structure. Every home is different and every home has differing privacy, lighting and existing structure particulars. Our trained building & design consultants will listen and scope your needs and wants and can make an obligation free visit to your home to advise you on what will work best for your backyard taking into account all the circumstances of your budget and existing property layout.

Some clients like to build in stages. We can build a locked up structure for you with the necessary allowances for pre-lay plumbing so that you can elect when you wish to proceed with adding a bathroom, kitchen or laundry and decorating as your budget and needs require.

No doubt you’ve heard all about the changes to the laws recently allowing people to derive an income from renting out granny flats in their back yards. We have seen an increase in interest from investors and have some great stories.

Whether you are someone with with overseas relatives or friends, wanting a delineated home work space, a FIFO worker – or wanting rental income from a FIFO worker, wanting your parents or children to live close by, a granny flat or home improvement from Granny Flats WA can be your solution.

We have a showroom that showcases some of the options we can provide, we’d love you to bring your loved ones in and take a look around.

I have been most impressed with the dealings I have had with Granny Flats WA. The service I received and process of purchasing a granny flat was easy and well informed. Mike is very personable and lovely to deal with. He went out of his way to assist and meet my various requests and I have no hesitation in recommending him for his integrity, attention to detail and friendliness.

Excellent from start to finish. Delivered exactly what we discussed. Our site Manager was always punctual and kept in touch, a pleasure to deal with. We are thrilled with the results of both our ensuite addition and renovation as well as our Granny Flat. Even nearly a year after the fact, if we have any questions or concerns they are quick to respond and always happy to help. Would not hesitate to recommend them, and would happily show our renovations and Granny Flat to anyone who was considering using GFWA.

Fantastic we are so pleased with our room extension to our house.  Dealing with this company has been a pleasure with everything delivered as promised on time and on budget
All the tradesman were brilliant and easy to deal with and the Site Supervisor was great to deal with.  Couldn't recommend this company more highly and both my wife and I are very very pleased.


- Michael Webster

Just a big Thanks to you all. It is our second renovation with your company and dealing with your workman has been a pleasure, again. It is our first bathroom reno and by having your team well organised made it all go according to schedule and on price. We are saving up for the other bathroom now. I do appreciate receiving the product and service that we agreed upon.
