The Process

How it works

Come to our showrooms and choose your design, or bring in your sketch so we can bring your ideas to life. We will come out to your property for a free site visit to establish the install costs. We can then give you the total project costings. Now the deposit will be paid so we can start with the Engineering, Energy reports and other relevant documentation. From here it’s on planning permission and then the building license. Once your plans are approved by council, all materials will be ordered and we will start on your building. Now we can give you a guaranteed delivery date.

A. A granny flat can be defined as a fully self-contained home extension that is built on the same plot of land that the main home is. Essentially, it is another, smaller home on your property. Usually, the granny flat is located to the rear of the main home, and it can share the backyard with the main home or have its own section of the yard fenced off. Local councils will dictate what the maximum size of a granny flat can be (usually no more than 70 square metres).
