We have designed the logical approval form below to make it even easier for you!

Logical Approval Form

Our Process



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.



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.



To begin, a Development Application (DA) for both the primary and secondary dwellings can be lodged and approved by council, or a Complying Development Certificate (CDC) issued by a private certifier (or council) for all works involved can be issued. After receiving approval and constructing the granny flat, an Occupation Certificate for the secondary dwelling can be issued. An OC issued for the first completed stage of a partially completed development will be subject to the condition that a subsequent OC for the entire development (both the primary and secondary dwelling) be obtained within 5 years of the initial occupation certificate’s issuance.

Starter Guide

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.

  • Block Size – Make sure your proposed granny flat and the primary dwelling have adequate privacy and separation.
  • Your property/block must also comply with these regulations

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 your 10.7.2 Planning Certificate and recommend this being one of your first steps.

The Planning certificate contains information to the property which can help determine whether the property can qualify under the SEPP for complying development approval, you can organise your 10.7.2 Certificate from the local council.

* Tables below exclude height setbacks which come into effect once the granny flat exceeds a height of 3.8 meters, this is generally avoided with our designs.
