Granny Flats WA Vision

I work with clients to ensure that the building work is a pleasant and reasonably simple experience.

TESTIMONIALS

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.

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.

I couldn’t recommend Granny Flats WA more highly. Dealt with Tom, Mike and their amazing team and had nothing but help and support to try and make my project work at my home.
– Sue Parora
We were nothing but impressed by the quality and the excellence in the finishing of the build. Nothing was too much, from the time Mum entered the showroom you showed her respect and understanding. Now she has settled in she is very comfortable and in good spirits, thriving being surrounded by her family. You all have been absolutely AWESOME!
