How to Quote an Outdoor Kitchen Build in Australia
An outdoor kitchen is a full build hiding behind a benchtop — cabinetry, appliances, and gas, water and power run out to an exposed spot. Here's how to quote one so the services and site work don't sink your margin.
Outdoor kitchens are some of the most profitable work a builder can take on — and some of the easiest to lose money on. The exposed site needs premium weather-resistant materials, and running new gas, power and plumbing out to it is rarely as simple as the client imagines. This guide covers what an alfresco kitchen quote should include, what it costs in 2026, and the compliance that has to be right.
What a good outdoor kitchen quote covers
An outdoor kitchen is cabinetry, benchtops and appliances sitting on top of a full build with services run to it. Price every layer:
- Site prep — demolition if needed, plus a concrete slab prepared and poured for the base.
- Cabinetry — weather-resistant carcasses: marine-grade ply, treated pine or powder-coated aluminium frames.
- Benchtop — engineered stone, granite or poured concrete, priced installed.
- Appliances — a built-in BBQ, and outdoor-rated fridge, sink and tapware.
- Services — new electrical, gas and plumbing connections, each quoted or clearly excluded.
- Approvals — permits and certification where gas, electrical or the structure trigger them.
- Rubbish removal and cleanup — the exposed site always generates spoil and offcuts.
Budget 2–4 hours just to prepare a detailed quote for a medium outdoor kitchen. It's a build with services, not a flat-pack — the itemised quote is what wins the trust and justifies the price.
Outdoor kitchen costs in 2026
Costs break down into cabinetry, benchtops, appliances and the service connections that are easy to overlook. Get current, trade-specific supplier pricing each time — stone and stainless move quarter to quarter. As a 2026 guide:
| Component | Typical cost | Notes |
|---|---|---|
| Cabinetry (basic) | $300–$600/lin m | Marine ply or powder-coated aluminium carcasses |
| Cabinetry (stainless) | $800–$1,500/lin m | Pre-fabricated units; 316 grade for coastal |
| Benchtop | $600–$1,200/lin m | Engineered stone, granite or poured concrete, installed |
| Built-in BBQ | $2,000–$5,000+ | Mid-range to premium (Weber, BeefEater) |
| Fridge, sink & tapware | $1,000–$3,000 | Outdoor-rated only |
Service connections sit on top of all of this. New gas or electrical runs to an exposed area often mean trenching, certification and inspection — real cost that belongs in the quote, not absorbed later.
Materials and appliances that last outdoors
Out here, durability isn't optional — everything has to handle UV, temperature swings and weather. Specify for the exposure:
- Stainless steel is the premium carcass, especially 316 marine grade in coastal areas, at upwards of $1,500/lin m.
- Marine-grade polymer (HDPE) or cement sheet over a galvanised frame is a solid mid-range option around $1,000–$1,200/lin m.
- Benchtops must take UV and spills — natural granite and durable engineered stones like Caesarstone or Dekton are popular choices.
- Specify outdoor-rated appliances only — a quality built-in BBQ from Weber or BeefEater starts around $2,500, a beverage fridge from $1,200.
- Check local parts and service are available for the appliances, so the client isn't stuck later.
Compliance: gas, electrical and waterproofing
Every service in an outdoor kitchen has a standard behind it, and none of them are negotiable. Get the certification into the quote:
- Gas installations must meet AS/NZS 5601.1:2022 — clearances, ventilation and pipe sizing — and be certified by a licensed gas fitter.
- Electrical work follows AS/NZS 3000:2018 (the Wiring Rules), including RCD protection for outdoor circuits.
- Waterproofing around sinks and splash zones should follow AS 3740:2021 to protect the cabinetry beneath.
- A new gas line often needs a council inspection; allow $200–$500 for permits and inspections before any work starts.
Common mistakes that eat your margin
- Not locating underground services. Hitting a water pipe, conduit or gas line during excavation means thousands in emergency repairs. Investigate before you dig.
- Misjudging access. Tight side access or a steep block means more manual handling, slower progress and possibly crane hire — all of which hit your labour.
- Under-specifying materials. Standard cabinetry and fixings won't last outdoors. Specify weather-resistant materials down to the screws, or you'll be back rebuilding it.
- Forgetting approvals. Gas and electrical alterations, larger structures and boundary setbacks can all trigger permits. Research them before you price the job.
- No contingency. Rock in the excavation, weather delays and design tweaks are normal outdoors. Build in 10–15% so they don't come out of your margin.
Pro tips for an outdoor kitchen quote that holds
- Measure twice — especially for appliance cut-outs; an off-size hole in a stone benchtop is expensive.
- Get written quotes from your electrical and gas sub-contractors before you commit a price.
- Factor in delivery and crane hire for heavy stone benchtops.
- Include rubbish removal and a full site cleanup as visible lines.
- Allow for weather delays when scheduling slab pours and benchtop installs.
- Advise the client on maintaining their specific materials, and consider passive ventilation for gas BBQs and fridges.
ServiceYak keeps your cabinetry, benchtop, appliance and service rates in a reusable kit, so you can itemise an outdoor kitchen on site — slab, cabinetry, gas and all — and send a professional PDF the same day you visit.
Frequently asked questions
How much does an outdoor kitchen cost to build in Australia?
It depends heavily on materials and appliances. Cabinetry runs $300–$600/lin m for basic weather-resistant carcasses and $800–$1,500/lin m for stainless, benchtops $600–$1,200/lin m installed, and a built-in BBQ $2,000–$5,000 — before services and site work.
Do I need council approval for an outdoor kitchen?
Often for the services rather than the structure. New gas installs need certification to AS/NZS 5601.1 and frequently a council inspection, and electrical work must meet the Wiring Rules. Larger structures or boundary setbacks can trigger a permit too — check before you quote.
What materials should I use for an outdoor kitchen?
Weather-resistant everything. Stainless steel (316 grade near the coast), marine-grade polymer or cement sheet over a galvanised frame for cabinetry, UV-stable engineered stone or granite benchtops, and outdoor-rated appliances only — right down to the screws and fixings.
