Deck Builders in the Sutherland Shire

Nobody has to sell Shire locals on outdoor living — it’s the whole point of living here. Between the beaches, the Port Hacking waterfront and the national park, your backyard deck is where Shire life actually happens. We’re Tony and Dean, the father-and-son deck builders Sutherland Shire families call when they want a deck that stands up to salt, sun and a lifetime of barbecues. We don’t build decks; we add a room to your home.

Decks built for Shire conditions

The Shire serves up two very different building environments, sometimes on the same street. Near the water — Cronulla, Burraneer, Caringbah South, Lilli Pilli — salt air is the enemy of cheap boards and mild-steel fixings. There, we lean on our specialty: Trex and Millboard composite decking that laughs off salt spray and never needs oiling, laid over properly protected subframes with the right fixings.

Further in — Gymea, Kirrawee, Engadine, Menai — bush-backed blocks bring shade, leaf litter and sometimes bushfire ratings into the picture, and dense Australian hardwoods like ironbark and spotted gum come into their own. Either way, we’ll recommend what’s right for your block, not what’s easiest to sell.

We’re deck builders serving all of Sydney, from our home base in the south-west to the Shire’s waterfront suburbs

Where we build in the Shire

We build right across the Sutherland Shire — Cronulla, Caringbah, Caringbah South, Burraneer, Lilli Pilli, Sylvania, Gymea, Miranda, Kirrawee, Sutherland, Engadine, Menai, Illawong, Alfords Point and surrounds. Waterfront platform at Burraneer or a family entertainer in Engadine — same crew, same care, because we treat your place like our own.

What we build

– Composite and hardwood decks — from low platforms to elevated waterfront decks
– Pool decks — smooth, cool-underfoot composite made for Shire summers
– Pergolas and awnings— shade for the long west-facing afternoons
– Balustrades, stairs and privacy screens — glass and wire options that keep water views open.

Councils and approvals

Most Shire projects sit with Sutherland Shire Council, and the honest answer on approvals is that it depends on your block — but it’s usually one of three paths.

No approval needed. A rear deck behind the building line can be exempt development if it stays under 1 metre above ground, sits at least 900mm from every boundary, and comes in under 25 square metres — or 15% of your home’s ground floor area on larger blocks. Most family-sized decks land over that limit, which is why the next path is the common one.

A complying development certificate. Faster and more predictable than a full DA, and the usual pathway for a decent-sized deck on a straightforward block. A private certifier can issue it.

A development application. Needed once the site gets complicated — and in the Shire it often does.

Waterfront blocks. If your land sits seaward of the foreshore building line, development is tightly restricted and Council assesses it carefully. Worth knowing before you plan a deck out toward the water, not after. You can check where the line falls on your block on Council’s foreshore building line map.

Bush-fringe blocks through Menai, Bangor, Barden Ridge and Engadine carry a BAL rating that decides which boards you’re allowed to use. We confirm your rating before specifying materials, not after.

Pool decks bring their own rule: raising a deck beside an existing pool fence raises the finished ground level, which can quietly make a compliant barrier non-compliant. We set deck height and barrier line together.

We’ve been through all of it plenty of times. We’ll tell you exactly what your project needs before we start, in plain English, no jargon.

Sutherland Shire decking FAQs

How much does a deck cost in the Sutherland Shire?

Installed rates run from $905 to $1,355 per square metre depending on the material, for a level site with a finished deck height under 500mm. That includes piers, substructure, fixings, boards, under-deck oiling, deliveries, waste removal and a final clean. Sloping blocks, elevated decks, stairs and balustrades are quoted separately.

Do I need council approval for a deck in the Sutherland Shire?

Often not. A rear deck behind the front building line, under 1 metre high, set back at least 900mm from every boundary and under 25 square metres can qualify as exempt development. Above that height, larger than that, closer to a boundary, or on bushfire-prone or foreshore land, you’ll need a complying development certificate or a development application through Sutherland Shire Council. We check your block before anything is ordered.

What's the best decking for homes near the water in the Shire?

For waterfront and near-beach homes we usually recommend Trex or Millboard composite with corrosion-resistant fixings — salt air destroys budget boards and mild-steel screws surprisingly fast. Dense hardwoods with stainless fixings are the timber alternative if you love the real thing.

Is composite decking too hot for bare feet around a pool?

Colour matters more than material, and both manufacturers say so themselves. TimberTech states that although its Advanced PVC decking is cooler to the touch than many other deck board products, all decking products will get hot in the sun, and the darker the colour, the hotter it will feel. AZEK Vintage is that Advanced PVC board, and it’s the coolest we install. Trex says its SunComfortable technology reduces heat build-up by up to 35 degrees Fahrenheit compared with their original boards, while noting the deck will still get hot in direct sun, especially in darker colours — that technology is in the Transcend Lineage range. Choose a lighter colour and either board is comfortable poolside. We’ll show you what each option costs.

Can you build a deck around my pool and still meet the fence rules?

Yes, but the deck has to be designed around the barrier from the start. Under AS 1926.1 a pool barrier must stand at least 1200mm above the finished ground level on the pool side, with no gap over 100mm at the bottom and a 900mm non-climbable zone kept clear. Raising a deck beside an existing fence raises that finished level, so a compliant barrier can quietly become non-compliant. We set the deck height and the barrier line together.

What about bushfire requirements around Menai, Bangor and Barden Ridge?

Blocks backing onto bushland through the western Shire are often bushfire-prone, and your BAL rating sets which boards are permitted. Several composite systems, including Woodevo, carry a BAL29 rating. We confirm your rating before specifying materials rather than after.

How long does a Shire deck project take?

Most residential decks take one to three weeks on site depending on size, height and extras like pergolas or balustrades. We’ll give you a clear timeline with your quote — and we stick to it.
