Commercial Kitchen Design: The Complete Australian Guide

A great menu can still fail behind a badly designed kitchen. When the layout forces chefs to cross paths, when the dishwasher sits a room away from the pass, or when the exhaust can’t keep up with the cooktops, every service becomes a fight against the building. Good commercial kitchen design does the opposite: it makes the busiest night feel calm. This guide covers the principles Australian operators need — workflow zones, the main layout types, ventilation, compliance and equipment selection — so you can plan a kitchen that works from day one, whether you’re building a café, a restaurant, or a high-volume production kitchen.

Start with workflow, not walls

The single biggest mistake in commercial kitchen design is starting with the floor plan instead of the flow. Before you place a single bench, map how food actually moves through your space:

Delivery → Storage → Preparation → Cooking → Plating/Service → Wash-up

Every one of those is a zone, and the goal is a layout where product moves forward through them without backtracking or crossing dirty and clean paths. Raw chicken should never travel back across a plating station. Dirty dishes should never cross the pass. When the zones sit in the right order, staff move less, cross-contamination risk drops, and service speeds up.

The five core zones in almost every commercial kitchen:

• Storage — dry store, cold store and freezer, sited near delivery. See the commercial refrigeration range.
• Preparation — benching, sinks and prep equipment, between storage and cooking.
• Cooking — the hot line: ranges, ovens, fryers, griddles and specialist stations like wok burners.
• Service / plating — the pass, hot-holding and expediting, closest to front-of-house.
• Wash-up — commercial warewashing and pot-wash, positioned so dirties return without crossing clean food.

The five commercial kitchen layouts

Once your zones are set, they get arranged into one of a handful of proven layouts. The right one depends on your space, your menu and your volume.

1. Assembly-line layout

Zones arranged in a single straight line, from prep to plating. Ideal for high-volume, repetitive menus — think burger kitchens, pizza, or any operation pushing the same dishes fast. Maximises throughput and makes staffing predictable.

2. Island layout

Cooking equipment is grouped in a central block, with prep, storage and wash-up around the perimeter. Great for larger kitchens where a head chef needs sightlines over the hot line, and where there’s floor space to circulate around the island.

3. Zone (or “zoning”) layout

The kitchen is divided into dedicated stations by function — a sauté station, a grill station, a cold/garde-manger station, a pastry station. Best for diverse menus and larger brigades where several chefs work different sections simultaneously.

4. Galley layout

Two parallel runs of equipment with a walkway between. Extremely space-efficient — the go-to for small footprints, food trucks and tight café kitchens. One or two chefs can reach everything without moving much.

5. Open kitchen layout

Part of the kitchen is visible to diners. Increasingly popular for the theatre it adds, but it demands quieter, cleaner equipment, excellent ventilation, and disciplined organisation because the customer sees everything.

Not sure which fits your site? CKC’s commercial kitchen design service produces custom layouts and 3D renderings so you can see the kitchen before you build it.

Ventilation and services: the part that fails inspections

Ventilation is where DIY kitchen plans come unstuck. Your exhaust canopy and make-up air must be sized for the total heat and combustion load of your cooking line — and high-output equipment like wok burners, chargrills and combi ovens throws off a lot.

Plan these services into the design from the start, not after:

• Mechanical exhaust designed to AS 1668.2 for your total kW load, with matching make-up air so the kitchen isn’t under negative pressure.
• Gas connected by a licensed gas fitter to AS/NZS 5601 — and remember NG vs LPG must be specified per site.
• Electrical capacity for three-phase equipment, plus enough GPOs in the right places.
• Plumbing and drainage — floor wastes, grease trap, and hot water sized for your warewashing.
• Grease management — canopy filters and a compliant grease trap sized to council requirements.

Compliance: Australian food-safety and council requirements

A commercial kitchen must be designed to pass a council health inspection and meet the Australia New Zealand Food Standards Code (Standard 3.2.3, Food Premises and Equipment). Key requirements that shape the design:

• Surfaces — impervious, smooth, cleanable finishes on floors, walls and benches (commercial-grade stainless, sealed floors, coved skirting).
• Handwashing — dedicated hand-wash basins separate from food-prep and pot-wash sinks, positioned where staff actually work.
• Separation — clear separation of raw and ready-to-eat handling, and of clean and dirty flows.
• Ventilation and lighting — adequate mechanical ventilation and lighting to code.
• Pest and waste — sealed construction, and appropriate refuse and grease storage.

Councils typically want plans approved before fit-out begins, which is exactly why a professional design (with proper drawings) saves time and rework. CKC’s design service provides drawings and assistance through each stage, including council approvals.

Selecting equipment that fits the design

Design and equipment are two halves of the same decision. A layout only works if the equipment fits the space, the power/gas services and the menu. A few principles:

• Right-size for volume. Over-buying wastes capital and floor space; under-buying bottlenecks service. Match capacity to covers.
• Standardise footprints. Choosing equipment on common bench depths and heights makes for a cleaner, more flexible line.
• Plan for the busiest station. The hot line usually sets the ventilation and services load — design around it.
• Leave room to grow. A little spare bench and a spare GPO now saves a rebuild later.

Common commercial kitchen design mistakes to avoid

• Designing around the room, not the workflow — the room should serve the flow, not the other way around.
• Under-sizing ventilation — the most common and most expensive fix after the fact.
• Forgetting the wash-up return path — dirties crossing clean food is a fail.
• No landing space — nowhere to put plates coming off the line, or product coming out of storage.
• Ignoring staff comfort — heat, noise and cramped aisles drive turnover in an already tight labour market.

Bringing it together

Great commercial kitchen design is invisible when it’s done right — the kitchen just works, service after service. Start with workflow zones, choose the layout that suits your space and menu, design ventilation and compliance in from the start, and select equipment that fits the plan. Do that, and you build a kitchen that’s faster, safer, cheaper to run, and easier to staff.
