We take immense pride in every granny flat we build, and that starts with using premium quality materials. Our commitment to using high-grade materials boosts the durability and longevity of your granny flat, while also boosting the overall value of your property.

Navigating the Approval Process? Our Granny Flat Builders in Box Hill Can Help
Building a custom granny flat requires obtaining the necessary approvals from local authorities. Depending on your property’s compliance with CDC requirements, approval can be obtained through a private certifier (CDC – Complying Development) or local council (DA – Development Application).
Our team of expert granny flat builders in Box Hill are well-versed in the approval process and can guide you through every step. We offer a FREE online assessment to evaluate your block’s size, assess points, and identify potential zones of influence, such as sewer mains, to determine build permissibility and identify any issues before we begin.

Additional Requirements and Regulations
There must be a primary dwelling on the block or approval for a primary dwelling must have already been obtained before the construction of your Granny Flat. Only one secondary dwelling can be built on a block of land, the Primary Dwelling being the main house and the secondary dwelling being the Granny Flat. The soft-to-hard ratio means that your Granny Flat design needs to cater for an open space of at least 24m2 in addition to the floor space of your Granny Flat. The maximum size of your secondary dwelling cannot exceed 60m2. This does not include a Garage or outdoor entertainment area. However, these areas will count towards your hard-to-soft ratio.
