Thinking about a modular BBQ or a prefabricated outdoor kitchen for your alfresco? This expert guide from Joyce Kitchens covers design, materials, layouts, costs and compliance for Western Australian conditions—so you can entertain with confidence.
Why choose a modular BBQ/outdoor kitchen
A modular BBQ system lets you build a high‑quality alfresco kitchen quickly using pre‑engineered modules—BBQ cabinet, sink, fridge, drawers, and even a barbecue island—that lock together for a seamless look. Compared to fully bespoke builds, modular outdoor kitchen solutions reduce lead times and simplify approvals, while still delivering the custom feel Joyce Kitchens is known for across kitchen renovations Perth, bathroom, laundry and custom cabinetry WA.
For personalised design and installation across Perth, consult a Kitchen designer Perth to explore modular options and finishes.
Definition: Modular BBQ
A modular BBQ is a prefabricated set of alfresco kitchen cabinets and benchtops designed to accept a built‑in BBQ, appliances and sinks. Modules can be arranged linearly, L‑shape, U‑shape, or as a corner outdoor kitchen, then secured and finished on‑site.
Core insights for WA homes
- Fast, tidy installs: Prefabricated outdoor kitchen modules minimise on‑site mess—ideal for established alfresco areas or balconies (subject to building rules).
- Weather‑ready: Choose UV‑stable and heat‑resistant benchtops; coastal homes often benefit from 316 stainless or porcelain/sintered stone.
- Flexible layouts: From small balcony bars to entertaining‑scale barbecue islands with seating.
- Compliance built‑in: Ventilation, clearances and services planned to align with AS/NZS gas and electrical requirements.
Our design-to-installation process
Joyce Kitchens brings the same award‑winning expertise we apply to indoor projects—shaker kitchen makeovers, contemporary kitchens, laundries, wardrobes—to your alfresco. Here’s how we deliver a durable, beautiful modular BBQ area.
- Consultation and measure – We review access, exposure (sun, Fremantle Doctor winds), BAL rating if applicable, drainage and substrate (paving, concrete, decking).
- Concept and layout – We refine the module mix: BBQ cabinet, sink, fridge, drawers, corner returns, and a possible raised bar for stools.
- Appliance selection – Perth‑popular BBQ sizes include 900–1200 mm built‑ins; beverage fridges are typically 600 mm underbench. We confirm gas type (LPG vs natural gas), IP‑rated GPOs and ventilation grills.
- Materials & finishes – Outdoor‑rated cabinetry and benchtops (porcelain/sintered stone, granite, stainless, compact laminate). Colourways to complement Hamptons, coastal, industrial or modern styles.
- Documentation & compliance – Plans show clearances per AS/NZS 5601 gas installations; electrical to Australian Standards; we work with licensed trades for Certificates of Compliance in WA.
- Install & handover – Modules are levelled, fixed, benchtops fitted, appliances set, services connected, sealants applied, and you receive care instructions.
Definition: IP rating (outdoor power)
Ingress Protection (IP) ratings indicate resistance to dust and water. Outdoors in WA, choose appropriately IP‑rated GPOs/switches (e.g., IP54+), installed by a licensed electrician.
Definition: BAL rating
Bushfire Attack Level (BAL) classifies bushfire exposure. Product and placement choices may change for BAL‑rated properties—always confirm with your designer and builder.
Materials and finishes that last outdoors
Outdoor areas in Perth face UV, heat and coastal air. Selecting the right finishes is critical for durability and safety.
Benchtops
- Porcelain/Sintered stone (e.g., Dekton, Neolith) – Excellent UV and heat resistance; ideal for BBQ surrounds and splash zones.
- Granite – Dense, heat‑tolerant natural stone; seal periodically.
- Stainless steel – Hygienic, heatproof; choose 316 for coastal homes.
- Compact laminate (outdoor‑rated) – Durable, UV‑stable options available; keep BBQ cut‑outs within manufacturer limits.
Note on engineered stone
Engineered stone is generally not recommended outdoors (UV) and is subject to a national ban on the supply of engineered stone products containing crystalline silica. Ask us about compliant alternatives like porcelain/sintered stone or stainless.
Cabinetry
- Powder‑coated aluminium frames with weather‑resistant doors.
- Outdoor‑rated compact laminate or marine‑grade 316 stainless in coastal zones.
- Soft‑close drawers, heavy‑duty runners, and custom cabinetry WA detailing to match your home.
Splashes and cladding
- Porcelain slabs/tiles with high heat tolerance near the BBQ.
- Ventilated cladding where gas appliances require airflow.
Engineered Stone vs Laminate (indoors) — quick comparison
For indoor benches associated with your project (kitchen or scullery), here’s a concise comparison. For alfresco benches, speak with our team about outdoor‑rated materials.
| Attribute | Engineered Stone (indoors) | Laminate (indoors) |
|---|---|---|
| Legal status in WA | Subject to national restrictions/ban; check current rules and alternatives | Widely available and compliant |
| Heat/UV performance | Good heat resistance; not UV‑stable outdoors | Moderate heat resistance; not suitable outdoors |
| Look & feel | Stone‑like aesthetics, seamless joins | Wide décor range; budget‑friendly |
| Indicative cost | Higher (alternatives: porcelain/granite) | Lower |
| Maintenance | Low; avoid harsh impact/heat shock | Low; protect edges from moisture/heat |
Compliance note: Discuss current regulations and safe alternatives with your designer.

What does a modular outdoor kitchen cost in Perth?
Budgets vary with size, appliances and finishes. The ranges below are indicative for 2025 Perth metro projects and assume good site access.
- Cabinet modules: $1,200–3,500 per module
- Benchtops: Porcelain/sintered stone $900–1,800 per lineal metre; stainless $550–900 per lineal metre; outdoor compact laminate $400–700 per lineal metre
- Built‑in BBQ: $1,200–5,000+ (brand/size dependent)

- Trades and compliance: Licensed gasfitting/electrical/plumbing $800–2,500+
Freestanding modular setups under an existing roof usually don’t need a building permit. New roofs, walls or plumbing changes may require approvals. Always verify with your local council and builder.
Compliance quick notes
- Gas BBQs must meet AS/NZS 5601 clearances and ventilation. Use licensed gasfitters for certification.
- Outdoor GPOs require suitable IP rating and RCD protection—licensed electricians only.
- Consider drainage, slip resistance and non‑combustible surfaces near the BBQ.
Practical planning checklist
- Measure your alfresco; note fixed walls, doors and posts.
- Choose a layout: linear, corner, U‑shape or barbecue island.
- Confirm BBQ size, fuel (LPG or natural gas) and required clearances.
- Pick outdoor‑rated benchtops and cabinetry suited to sun/coastal exposure.
- Plan fridge ventilation and weather protection (doors or roller shutter).
- Locate IP‑rated power, lighting and a gas bayonet/hard line.
- Allow a landing zone either side of the BBQ for safety.
- Check BAL rating, strata by‑laws and council rules if applicable.
- Book licensed trades for electrical, plumbing and gas compliance.
- Schedule installation outside of stormy periods where possible.

FAQ
What is a modular BBQ and how is it different from a custom outdoor kitchen?
A modular BBQ uses pre‑engineered cabinets and benchtops that configure into your space quickly, while a custom outdoor kitchen is built entirely bespoke. Modular delivers faster installs and sharp value, with plenty of style and appliance choices.
Can I move or add to my modular outdoor kitchen later?
Yes. Most prefab outdoor kitchens allow you to add modules such as drawers, corner returns or a drinks fridge later. Changes to gas, power or water should always be handled by licensed WA trades.
What materials are best for Perth’s climate?
Porcelain/sintered stone, granite, stainless steel (316 near the coast), powder‑coated aluminium frames and outdoor‑rated compact laminate. These materials handle UV, heat and coastal air better than indoor products.
Do I need council approval for a modular BBQ area?
Generally no for freestanding modules under an existing roof. You may need approvals for new structures, external plumbing or significant alterations. Always confirm with your local council or builder.
How much does a modular outdoor kitchen cost in Perth?
Typical projects range from $6,000–$18,000+ depending on size, appliances and finishes. Premium porcelain or stainless benches, larger BBQs and extra trades increase the total.
