Create the outdoor entertaining area you've always wanted with a custom-built deck from ACG Built. We design and construct beautiful timber and composite decks, pool surrounds and balcony decks across Caringbah, Cronulla, Miranda, Burraneer, Gymea, Kirrawee, Woolooware and surrounding Sutherland Shire suburbs.
A well-built deck transforms the way you use your home. It's where summer barbecues happen, where the kids play, where you unwind with a cold drink after a long week. At ACG Built, we've constructed over 100 decks across the Sutherland Shire — and every single one was built to stand the test of time.
We work with premium Australian hardwoods like spotted gum, blackbutt and merbau, as well as high-quality composite decking for a low-maintenance alternative. Our team handles every detail: engineered footings, steel subframes where needed, perfectly spaced boards, concealed fixings and quality oiling or staining to protect your investment.
From a simple ground-level deck in Caringbah to a multi-level entertaining deck with built-in seating overlooking the water in Burraneer — we bring the same precision and pride to every project.
From design to final oiling — complete deck construction services
Premium Australian hardwoods including spotted gum, blackbutt and merbau. Beautiful natural grain with professional oiling and finishing for long-lasting protection.

Slip-resistant decking around your pool area. Designed for safety and style with proper drainage and durable materials that handle splashing and sun exposure.
Elevated decking for upper-storey balconies and terraces. Proper waterproofing, drainage and balustrading to meet all safety and building code requirements.
Bespoke designs that make the most of your space. Multi-level decks, built-in seating, planter boxes, privacy screens and integrated lighting — all customised to your lifestyle.
Safe, code-compliant deck stairs and landings that connect your outdoor spaces. Handrails and balustrades in timber, glass or stainless steel to match your deck design.
A deck might look simple, but building one that stays beautiful and structurally sound for decades takes real skill. Our decks aren't just nailed together — they're engineered with proper footings, treated subframes, stainless steel fixings and precise spacing that accounts for timber movement in our coastal climate.
We're deck specialists, not generalists. That means we know our timbers, we understand how decks perform near salt water in Cronulla, on sloping blocks in Burraneer and in family backyards across Caringbah and Miranda. Every deck is built for its specific location and the way your family will use it.
