Composite Decking Across The Sutherland Shire.
Open Air Build designs and builds low-maintenance composite decks for homes across the Sutherland Shire and surrounding southern Sydney suburbs — backed by a 25-year warranty, with builds starting within 10 days.
Composite decks, suburb by suburb.
A closer look at some of the areas we build in most often — if your suburb isn't listed here, it's very likely still in our patch. Get in touch and we'll confirm.
Composite Decking in Cronulla
Cronulla's beachside homes cop plenty of sun and salt air, which is exactly where composite decking earns its keep over timber — no re-oiling every season, no fading deck boards by summer's end.
Composite Decking in Miranda
With so many established homes around Miranda extending their outdoor living space, we build a lot of entertaining-area decks here — often tied into existing patios or alfresco zones.
Composite Decking in Sutherland
Sutherland's mix of older and newer homes means we're regularly replacing tired timber decking with composite boards, frequently reusing the existing substructure to keep build time and cost down.
Composite Decking in Caringbah
Caringbah's larger blocks lend themselves to bigger deck footprints — we've built everything from simple courtyard decks to full wraparound entertaining spaces in this area.
Composite Decking in Menai
Menai's bushland-adjacent properties often call for decks that handle sloped or uneven blocks well — composite decking's low-maintenance nature makes it a practical fit for these harder-to-reach areas.
Composite Decking in Engadine
Families in Engadine are often after decks built for everyday use — kids, pets, outdoor furniture — rather than just a display feature, and composite boards hold up well to that kind of daily wear.
Composite Decking in Sylvania
Sylvania's waterfront and near-water properties benefit from composite decking's resistance to moisture and swelling, without the annual maintenance timber decking near water usually demands.
Composite Decking in Gymea
We build a good number of pool-adjacent decks in Gymea, where composite boards' slip resistance and cool-underfoot properties make them a practical choice around pool areas.
And plenty more of the Shire.

Service area questions, answered.
Do you build outside the Sutherland Shire?
Our core service area is the Sutherland Shire, but we do take on select projects just outside it depending on scope and location. Get in touch with your suburb and we'll let you know.
Does it cost more if I'm further from your base?
For most suburbs within our core service area, no — travel is already factored into our standard pricing. We'll always flag it upfront if your location affects the quote.
How do I know if you cover my exact street?
The easiest way is to pop your suburb into the quote form below. We'll confirm coverage and, if we're not the right fit for your location, we'll tell you honestly rather than waste your time.
