There are a few requirements which your property needs to meet, to be permitted to do so.( this is compiled of land size / frontage and other items.) Follow our Complying Development table below as your starting point to the 10 day express approvals we offer. This means you are not subject to the long strenuous Council D.A Submissions ( up to 12 weeks) which you would undergo nominally.
The below complying development table table outlines the Minimum requirements:

Prior to Coming out to View Your property, we ask for your Section 149 and Sewer Diagram, and also review your property on Google maps, to assess wether your property has all the minimum requirements as we outlined in the first step.
