Approvals
Navigating Sutherland Shire Council Approval
A granny flat in the Sutherland Shire typically follows one of two approval paths. A Complying Development Certificate is the faster route for blocks that meet the standard planning rules. A Development Application through Sutherland Shire Council applies where a site sits within a special zone, such as a foreshore or environmentally sensitive area, which the Shire has more of than most regions.
As a guide, complying development requires at least 450 square metres of land, a 12 metre frontage, a 3 metre rear setback and 0.9 metre side setbacks. We assess your block properly, advise on the right path, and manage the full approval process so you avoid the guesswork.

Why Sutherland Shire Homeowners Choose 5 Star
Sutherland Shire homeowners choose us for one clear reason: quality they can see and trust. We have built granny flats across Sydney for more than 15 years, earned hundreds of 5-star reviews, and won recognition as an award-winning builder. In a premium market, that track record matters.
Every build carries a 6-year structural warranty and our 4-week approval guarantee, and we invite you to experience the standard for yourself at our display home at 2 Mary St, Blacktown. Touch the finishes, test the materials, and picture what your own granny flat in the Sutherland Shire could look like.
Communication is a big part of why our clients recommend us. From the first site visit onward, we keep you informed, explain the choices in front of you, and give honest advice rather than a sales pitch. In a premium market where expectations are high, that clarity matters, and it is one of the reasons so much of our work comes from referrals across the Shire and the wider Sydney region.

We always focus on quality, regardless of the budget because we want to build sturdy and long-lasting flats. We use the best possible materials and double-check everything to ensure you don't face any problems down the line.

Pricing
What Will Your Granny Flat Cost in the Sutherland Shire?
The cost of a granny flat in the Sutherland Shire reflects your design, your site and the finishes you choose. Premium finishes and more complex sites, including sloping or foreshore blocks, influence the final figure. We quote after inspecting your property so the price is accurate and complete, with a clear itemised breakdown and no hidden extras.
Given the high property values across the Shire, many homeowners view a granny flat as a value-adding improvement rather than a cost. A quality second dwelling can lift the overall worth of your property and broaden its appeal to future buyers, on top of any rental income it earns. We are happy to talk through the numbers for your specific block so you can make a confident, informed decision.
