Granny Flat Process

As one of Perth's most awarded granny flat builders, Summit has a streamlined six step process, which means you can get the keys to your flat sooner. See for yourself how easy it is to build with us.

  • Step 1 out of 6

    Obligation Free Site Inspection

    One of our experienced Design Consultants will organise a time to meet with you at your home to discuss your ideas, dreams, wish list and budget.

  • Step 2 out of 6

    Design Meeting

    This is where your ideas come to life. Your Design Consultant presents you with a custom designed concept crafted to suit your lifestyle and budget. Your input is important, and your Design Consultant will listen and incorporate your feedback and ideas so you’re fully satisfied with the planned granny flat.

  • Step 3 out of 6

    Presentation Meeting

    We want your granny flat to be perfect and will present you with: (1) Final Plans, (2) HIA fixed price contract, (2) A full breakdown of what work we will be completing (specification of work). From here on in, we will look after the whole process including building permits with your local council.

  • Step 4 out of 6

    Prestart Meeting

    Meet with your Prestart Consultant at our stunning Style Studio to pick out your colour selections, fittings and fixtures.

  • Step 5 out of 6


    Your granny flat’s construction will be managed by your dedicated Site Supervisor. A final timeframe will be provided to you before site commencement. The building industry is currently experiencing the effects of the Global Shortage caused by COVID and so you may be affected by these delays.

    It's time to make your little house a home.


  • We are extremely happy we chose Summit to build our granny flat. We can't speak highly enough of our design consultant, Drew. His advice and design ideas were invaluable. Not only was he very patient with us but the overall layout of the build he designed was spot on. The build quality is excellent and all the trades we observed were very professional. Our site supervisor Dean, has gone above and beyond what we could have wished for. He's done an excellent job of completing our granny flat, we couldn't be happier.

    Gary - Summit Granny Flats
  • There was a difference between Summit and the other builders we approached. Drew understood our lifestyle and the end result was a design that needed very little modifications. The actual build was painless - our site supervisor Rob and client administrator Sarah Jane, were always there to explain things and keep us informed. The tradesmen were also top notch and we were so happy with the end result.

    Mia - Summit Granny Flats
  • Drew was so patient and helpful during the design stage. He worked diligently with our original designer and landscaper as well as the company installing he pool to ensure that nothing would be compromised

    Kelly-Anne & Murray
  • We were quite particular about the look we wanted to achieve and the Granny Flat Design Consultant had clever suggestions to get the effect we wanted. We were kept informed at all stages of the build and everyone who worked on the building was considerate and kept the disruption to a minimum.

    Janet & David
  • The Summit Granny Flats team were very accommodating and helpful. Our Design Consultant was very courteous and helpful, nothing we requested was deemed to be unreasonable and he went out of his way to deliver us a brand new home which was on time, on budget and altogether, a very pleasant experience.
