The build time for our Granny Flats is typically 12 weeks. You’ll also need to factor in time for site visits, feasibility study and council approvals. Council approval can be time-consuming, taking anywhere from a few weeks to a few months. If possible, our design team will obtain a Complying Development Certificate (CDC) to ensure your project can get underway as soon as possible. Your Granny Flat consultant will keep you updated on accurate time frames and progress so you’ll always be kept in the loop.

A Section 10.7 certificate (2&5) is otherwise known as a Planning Certificate through council. This document gives us all the environmental information and planning requirements for development of your property/block, for example if you are: Flood affected, Bushfire affected, Mine subsidence, Heritage listed, and any other relevant zoning regulation information.

A Section 10.7 certificate is not a development approval, however, if you're looking to build, the documentation required for your approval will be dependent on what is shown in the Section 10.7 Certificate relating to your block of land. If your property is in a flood zone, you may require a flood report and may need to build the floor level of your dwelling higher, or you may not be able to build at all. Council update this information every 6 months as these factors can be impacted by development in your surrounding area, you can apply online or in person and the cost varies from Council to Council.
