The first step is to survey your site and check on all compliances with regard to the SEPP and all relevant Australian standards. We also provide on-site consultation on your preferred design and budget objectives. This is a critical step as it applies to the approval and design of your new granny flat.
Approvals And Process
The building stage involves being mindful of the available timeline so we don’t disrupt you, neighbours or your tenants. Our staff are trained to be professional, clean and tidy as they enter and exit your property. This is especially important on sites with existing occupants, as granny flat properties always are.
The next step is to design your granny flat and get it approved, either by our private certifier or by your local council. The latter is preferred due to the ease of assessment and time-savings. We will of course design your granny flat to be modern in appearance and with durability in mind. We will diligently consult with you on this.
There are many things to consider when building a granny flat, we have put together this guide to help you get started whether you’re interested for family reasons or investing.

It’s important to point out there are also other factors that can prevent you from building a granny flat, or incur additional costs to comply with the SEPP and building regulations. We highly recommend ordering 149 Certificate and recommend this being one of your first steps. The 149 certificate contains information to the property which can help determine whether the property can qualify under the SEPP for a complying development approval, you can organise your 149 certificate from the local council.
