Deck Builders in the Hills District

Q: How much does a deck cost in the Hills District?

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. Hills District projects range from compact entertaining decks to elevated decks on sloping acreage, and those are very different builds — elevated decks, stairs and difficult access are quoted separately. Use our deck cost calculator for a ballpark on your numbers and we'll firm it up with a free quote. No surprises — that's a promise.

Q: Do I need council approval for a deck in the Hills District?

It depends on size and height. Smaller, low-level decks can qualify as exempt development; larger or elevated decks need approval through The Hills Shire or Hornsby councils. We'll tell you which applies to your project before you spend a dollar.

The Hills is entertaining country. Big blocks, big backyards, and families who actually use them — weekend barbecues, kids in the pool, three generations around one table. We’re Tony and Dean, the father-and-son team behind UrbanArch Building, and we build the decks and pergolas those weekends happen on. We don’t build decks; we add a room to your home.

Decks made for Hills District living

Hills District homes give you room to think big — and the most-loved projects we build here are full outdoor rooms: a generous deck flowing off the kitchen, a pergola or awning overhead so summer sun and sudden storms don’t end the party, and privacy screens so you can relax without waving to the neighbours.

Newer homes around Kellyville and North Kellyville often suit the clean, uniform look of composite — we’re Trex, Millboard and TimberTech specialists, and composite means no oiling weekends, ever. Established homes in Castle Hill, Baulkham Hills and West Pennant Hills often call for the warmth of hardwood decking like, merbau, spotted gum or blackbutt. We’ll talk you through both honestly — including what each costs over ten years, not just on day one.

Where we build in the Hills

We build right across the Hills District — Castle Hill, Baulkham Hills, Kellyville, North Kellyville, Bella Vista, Glenhaven, Dural, Round Corner, Cherrybrook, West Pennant Hills, Winston Hills and surrounds. Acreage at Dural or a family block in Kellyville, the care is the same — we treat your place like our own.

What we build

– Entertaining decks — ground-level and elevated, sized for real family gatherings
– Pergolas and awnings — timber or aluminium, freestanding or attached
– Pool-side decks — smooth, splinter-free composite that’s kind to bare feet
– Stairs, balustrades and screens — the finishing touches that complete the room

Approvals, acreage and bushfire fringe

Most Hills projects sit with The Hills Shire or Hornsby councils. Acreage properties around Dural, Glenhaven and Kenthurst can carry bushfire-prone land ratings that shape material choices — we’ll check what applies to your block and recommend compliant options up front, in plain English.

How much does it cost to build a deck in the Hills District?

Wondering what decking costs per m²? The table below shows indicative installed prices per square metre for the materials we build with most in Sydney, on a level site with a finished deck height under 500mm. Use it as a starting point, then run your own numbers through our deck cost calculator.

Prices are indicative Sydney installed rates for 2026 and include the subframe, piers, fixings, boards, under-deck oiling, deliveries, waste removal and a final clean — not just the boards. That’s why they sit above the $350–$500 per square metre quoted elsewhere, which is usually materials only, or supply-and-lay by an unlicensed installer. Sloping blocks, difficult access, elevated decks, stairs, balustrades and pergolas add to the rate, and a quote that’s $200/m² cheaper usually means those things come back later as variations. Every deck is measured on site — request a free consultation for a firm figure.

Hills District decking FAQs

Should I choose composite or timber for a Hills District deck?
Both work beautifully here. Composite (Trex, Millboard, TimberTech) wins on zero-maintenance and pool-side comfort; hardwood wins on natural warmth and can suit established homes. We’ll give you an honest side-by-side, including long-term costs, so you choose with your eyes open.

Can you build a deck and pergola together as one project?
Yes — and it’s usually the smartest way to do it. Designing deck and pergola as one structure means cleaner lines, better engineering and one approval process instead of two.

Do you build on acreage properties?
We do — Dural, Glenhaven, Kenthurst and beyond. Acreage blocks sometimes involve bushfire ratings that affect material selection, and we’ll sort that out for you as part of the quote.

Do I need council approval for a deck in the Hills District? It depends on height and size. Smaller, low-level decks can qualify as exempt development; larger or elevated decks need approval through The Hills Shire or Hornsby councils. We’ll tell you which applies to your project before you spend a dollar.

How much does a deck cost in the Hills District?
Most of the decks we build in the Hills land between $$20,000 and $80,000, depending on size, material and site. A ground-level hardwood deck sits at the lower end; a large elevated composite deck with a pergola over it sits at the top.
