Granny Flats

Custom Granny Flats from $129,000

Granny flats have evolved beyond the old tin shed to become a versatile and affordable solution for Perth families in need of extra living space for a huge variety of reasons.

Addstyle Master Builders is among the most experienced granny flat builders in Perth, delivering award-winning extensions and home renovations that are so much more than a place for granny to sleep.

With fully customised designs starting at just $129,000 and delivered in less than 3 months, Addstyle granny flats are a great way to add a comfortable space and long-term value to your home.

Why Add A Granny Flat?

There are so many ways homeowners can benefit from building a granny flat in Perth:

  • Renting out to FIFO workers, as an Airbnb or a separate room
  • Secluded backyard retreat or studio
  • Games or entertainment room
  • Living space for teenagers or young adults
  • Keeping aging or extended family close by
  • Guest house
  • Home office
  • Craft room or work shed

In fact recent changes to ancillary dwelling laws allow Perth families to earn income from renting out a granny flat up to 70m2. Previously only immediate family could live in the space which is great news for homeowners looking for a bit of extra income.

Addstyle granny flats are fully customised to meet your needs, budget and space allowance. Plus, building a granny flat can add value to your home long-term by increasing the living space with a design that seamlessly matches the existing house.

I was introduced to Addstyle through one of their young architects who bought a guitar from me! I was considering building a small home studio on a spare bit of land I had behind my garage. He recommended Addstyle for the sort of project that i envisaged. The decision was sound. Between Joe, the architect, and myself we concocted the best way to use the available space. The construction team headed by Simon Hill and John Peacock proved to be very helpful and flexible. The workmanship was excellent and the contractors considerate and friendly. The project was completed on time and the site was left tidy. Some areas of the contract were ambiguous, however Addstyle did everything in their power to make me happy with the finished result. The whole team is very professional , including the Dee and the rest of the office staff. Special thanks go to Simon for being always available and personally taking care of any misunderstandings. Good company!!

Teena Dyer

A pleasure to deal with from the very beginning in getting quotes to the final handover and follow up. Great team of Tradies who were always polite and friendly and fantastic guidance and advice from Dee in the office. Would not hesitate to recommend Adstyle!

Absolutely cannot fault this company. From start, with never ending questions to the end this company goes above and beyond what you would expect. Cannot fault in any way.

Lara Skinner

Addstyle did our kitchen renovation earlier this year in our Claremont house! I was blown away with the service from their tradies and the site supervisor. Addstyle understood from the very beginning the image we wanted to create and it was so well delivered. The workmanship was second to none. I highly recommend such a professional company to anyone that is a little hesitant of renovating. Lara and Russell Skinner

Kate Ranson

Best Reno team in Perth! They converted my single garage into an amazing laundry/scullery and the end result is fantastic. The service was next to none from the initial design stage, through the building and construction stage and to handover. All the staff and tradesmen we're exceptionally helpful and went over and above to make this process smooth and efficient. Thankyou for such a great service and probably the best laundry in Perth.

Ted Currie

Extremely happy with the new look. Overall, an enjoyable experience, especially considering the challenges we gave the Construction Team. A pleasure to meet these friendly, flexible & efficient individuals.

Wayne Dwyer

The team at Addstyle were amazing. Very professional with great advice on what options were available to us throughout our renovation.

Addstyle was the last on my list as I searched and got several quotes from other builders to carry out an extension to our very old and treasured home. I walked the streets of Menora and having seen their work I thought they would be far from my budget. After my first consult with Simon I was sold! The experience with Addstyle has been a very positive and the final finish product has surpassed all our expectations. The build has not interfered with our life and we have found ALL Addstyle staff have gone far beyond to create such beautiful extension. Rede has been a huge support to me and his knowledge and expertise has made my life easier. Nothing has been too much for him to do. I would also like to mention Dee and thank her for all her help to get this project on its way. From my initial meeting with Simon Pullen to my daily contact with Rede I hold Addstyle in the highest regard as a builder, workmanship, contractors etc will recommend them to anyone. The feedback from family, friends and strangers to the finished renovation make me very glad I chose Addstyle and I will continue to use them to complete my home.


We are so glad to have chosen Addstyle to design and build our carport and workshop, to our federation style property. From the start, the advice and support has been superb, making the the whole process easy and uncomplicated. The build quality and attention to detail is outstanding, and we are extremely delighted with the result. All stages of the development and build were wonderfully managed. We'd especially like to thank Liam, our site manager, for his exceptional help and support in making this an even more streamlined and easy process. We felt that Liam went above and beyond to assist with our queries, giving us sound advice and guidance as well as liaising with other trades on our behalf. We consider Liam to be an asset to the Addstyle team. We highly recommend Addstyle, for their professionalism, vision and expertise.
