Commercial Kitchen Layout Guide: 5 Layouts Compared (Australia 2026)
Choosing the right commercial kitchen layout is the single most consequential decision in any new venue fit-out — it dictates how many covers you can push per shift, how easily your kitchen staff can move during peak service, how much you spend on ventilation and refrigeration, and how cleanly you can pass a council health inspection. The components of a commercial kitchen, the brigade size, the menu and the available kitchen space all push you toward one of five main types of commercial kitchen layouts: assembly line, island, zone-style, open kitchen, and galley. This commercial kitchen design guide compares all five — with diagrams, pros and cons, space requirements, best-for recommendations, and a decision framework table to help you pick the right commercial kitchen layout for your menu, your seat count and your floor plan.
It pairs with our restaurant kitchen setup guide, commercial kitchen ventilation requirements, health inspection checklist and our existing 5 commercial kitchen layouts explained guide. All Australian standards, dimensions and price ranges are local.
Key Principles of Commercial Kitchen Design: Components and Workflow
Before picking between assembly line, island, zone, open kitchen or galley, every successful commercial kitchen layout design follows the same five principles:
- One-way workflow. Stock should travel from receiving → storage → prep → cooking → plating → pass → dish pit return without doubling back on itself. Backtracking is where cross-contamination, ticket-time blowouts and OH&S incidents happen.
- The kitchen work triangle (or work square). The cook, the prep, and the storage zones should sit within easy reach of one chef — typically a triangle no longer than 2 m on each side per station, so chefs do not waste steps during service.
- Safety and ergonomics. Australian best practice is 900 mm minimum aisles for single-chef walking lanes and 1200 mm minimum where two chefs must pass shoulder-to-shoulder or where heavy trolleys move. Anything narrower fails an OH&S review and slows service.
- Hygiene zoning. Raw and cooked product must be physically separated, with a dedicated handwashing basin at every workstation that handles open food. Australian food safety standards specifically require this.
- Ventilation and air balance. Every cooking line needs an exhaust canopy sized to AS 1668.2, with make-up air at 80–90 % of exhaust volume. Skipping this is the most common compliance failure at the first council inspection.
Layouts that respect all five principles outperform layouts that pile equipment in by floor plan alone, even when the more disciplined layout uses less floor space.
Layout 1: Assembly Line Layout
Description and diagram
The assembly line layout arranges every station in the exact linear order a dish is built — usually prep → cook → plate → pass, all along a single wall or running through a central island. Think of a Subway, a Guzman y Gomez burrito line, or any high-throughput pizzeria.
📐 Diagram brief: Top-down floor plan showing prep table → make-line refrigeration → grill/cooktop → assembly bench → pass window, in one continuous straight line with one chef per station. Aisle behind the line for runner access; expediter at the pass end. Minimum 3 m × 6 m envelope.
Best for
- Fast food, quick-service restaurants (QSR), pizza, sushi train, burger joints
- Any menu with a fixed, limited build sequence
- High-volume venues pushing 200+ covers per service
Space requirements
- Minimum 3 m × 6 m for a basic single-line setup
- 4 m × 8 m more realistic for a full QSR with prep + cook + assembly stations
Pros and cons
| Pros | Cons |
|---|---|
| Fastest possible per-dish throughput | No flexibility — only suited to fixed menus |
| Easy for new staff to learn (one station, one task) | Single point of failure (one station down stops the line) |
| Low equipment count per cover served | Boring for chefs; high turnover risk |
| Minimal walking distance | Cannot scale up without rebuilding the line |
Australian considerations
Assembly-line layouts often share a single canopy across all stations — make sure the canopy is sized for the heaviest-duty appliance, not the average. Pair with a passthrough dishwasher at the end of the line to keep clean stock cycling back to prep.
Layout 2: Island Layout
Description and diagram
The island layout places all primary cooking equipment in a central block under a single island canopy, with prep, cold and dish stations around the perimeter walls. The brigade works inward toward the island, which makes it the showpiece of the kitchen.
📐 Diagram brief: Top-down floor plan showing a central rectangular cooking island (6-burner range, combi oven, chargrill, fryer, salamander) under a hanging island canopy. Perimeter walls: prep bench + sinks on one side, cold-line prep fridges + plating bench opposite, dish pit at the entry, dry store along the back wall. Minimum envelope 5 m × 5 m (25 m²).
Best for
- Full-service restaurants of 60+ seats
- Hotel kitchens with multiple service periods
- Restaurants that want a single visible workflow hub and an executive chef sightline across every cooking station from the perimeter benches
Space requirements
- Minimum 25 m² for a workable island
- 35–55 m² recommended for medium-large venues
- 1.2 m clearance on every side of the island for chef circulation
Pros and cons
| Pros | Cons |
|---|---|
| Single point of supervision for the head chef | Higher canopy and fire-suppression costs (single big island canopy) |
| Excellent menu flexibility — every cook station is in reach | Demands more floor area than galley or assembly line |
| Looks impressive in open-kitchen and demo settings | Make-up air design is harder than for wall canopies |
| Easy to expand by adding equipment to the island | Service runners must walk around the island to the pass |
Australian considerations
Island canopies need 20–30 % more exhaust airflow than wall canopies of equivalent length under AS 1668.2 because there is no back wall to contain the plume. Budget accordingly.
Layout 3: Zone-Style Layout (Station Layout, French Brigade)
Description and diagram
The zone layout (also called the station or brigade layout) groups equipment into discrete zones owned by a chef de partie: saucier zone, garde manger zone, entremetier zone, pâtissier zone, plonge zone. It is the layout descended from Auguste Escoffier's French brigade system and remains the gold standard for fine-dining and large à-la-carte restaurants.
📐 Diagram brief: Top-down floor plan showing 4–6 separate zones each labelled: HOT (6-burner range, oven, fryer, salamander), COLD (prep fridge, plating bench), GRILL (chargrill, salamander), PASTRY (mixer, deck oven, marble slab), GARDE MANGER (cold prep). Walking lanes 1.2 m between zones. Walk-in cold and dry stores on perimeter. Pass between hot and cold zones. Minimum envelope 5 m × 6 m (30 m²).
Best for
- Fine dining, modern Australian à-la-carte, hatted restaurants
- Large hotel and resort kitchens running multiple outlets
- Any menu with high complexity (8+ sections on the dinner card)
Space requirements
- Minimum 30 m² for a four-zone brigade
- 60–100 m² for a full Escoffier brigade with pastry section
- 1.2 m minimum aisles between zones
Pros and cons
| Pros | Cons |
|---|---|
| Highest possible menu complexity and plate quality | Largest floor area requirement of any layout |
| Specialised chefs working a single craft | Highest equipment count = highest fit-out cost |
| Easy to run multiple services in parallel (lunch + dinner) | Communication between zones becomes a head-chef job during service |
| Scales gracefully as the brigade grows | Lowest covers-per-square-metre |
Australian considerations
Zone layouts often spread equipment across multiple canopies, so the make-up air balance becomes more complex. Engage a mechanical engineer at design stage to model airflow across the whole kitchen, not zone by zone.
Layout 4: Open Kitchen Layout
Description and diagram
The open kitchen layout removes the wall between the kitchen and the dining area. Diners see the brigade at work over a counter, pass or low partition. It is now the default layout for modern Australian small-plates restaurants, woodfired pizzerias, ramen bars and sushi venues, and a powerful piece of theatre when the executive chef runs a disciplined service.
📐 Diagram brief: Top-down floor plan showing kitchen line along one side of the dining room, separated by a counter with low or no overhead. Hot line + cold line in view; dish pit + storage behind a partition out of customer view. Diners' bar stools or banquettes face the line. Heat lamps + heated pass at the diner-facing edge. Minimum kitchen depth 2.5 m behind the line.
Best for
- Modern Australian, izakaya, ramen, sushi, woodfired pizza, dumpling bars
- Restaurants where the cooking show is a marketing asset
- Venues with limited rear floor area but a deep dining room
Pros and cons
| Pros | Cons |
|---|---|
| Massive marketing value — diners watch the chefs work | Demands the cleanest, most disciplined brigade in hospitality |
| No need for a separate plating-to-pass corridor | Noise and heat carry into the dining room |
| Connects the kitchen team to the customer experience | Make-up air balance harder; canopy must capture without smoke spilling into the dining room |
| Saves floor area otherwise lost to walls and doors | Dish pit and chemical storage still need a back-of-house area |
Australian considerations
Open kitchens must meet AS 1668.2 exhaust rates and keep capture velocity high enough that grease vapour does not spill into the dining room. A higher-spec proximity hood or ESP (electrostatic precipitator) stack is often required. Run a smoke test before opening night.
Layout 5: Galley Layout
Description and diagram
The galley layout runs two parallel rows of equipment facing each other across a central walkway. Named for the ship's galley, it is the default layout for narrow shopfronts, food trucks, container kitchens, and small cafés.
📐 Diagram brief: Top-down floor plan showing two parallel lines of equipment 1.2 m apart, facing each other across a central aisle. Hot line on one wall (6-burner range, combi oven, fryer), cold line on the opposite wall (prep fridges, plating bench, sink). Single canopy over the hot line; minimum overall depth 2.4 m + 2.4 m = 4.8 m. Single chef can reach both lines without turning.
Best for: Small Commercial Kitchens and Ghost Kitchens
- Cafés and small restaurants (≤30 seats) — the classic small commercial kitchen layout plan
- Food trucks, container kitchens and ghost kitchens
- Narrow inner-city tenancies and laneway venues
- Any commercial space where every metre of floor area carries a rent cost
Space requirements
- Minimum 2.4 m wide between lines
- 4.8–6 m total envelope width (line + aisle + line)
- 4–8 m deep depending on cover count
Pros and cons
| Pros | Cons |
|---|---|
| Smallest floor area per cover served | Limited to small brigades (1–3 chefs at peak) |
| Single canopy keeps fit-out cost down | Hot line opposite cold line can stress refrigeration if airflow is wrong |
| Single chef can run two lines solo | No space for a dedicated prep station — prep happens off-peak |
| Cheapest to build and operate | Crammed during service if a runner or expediter joins the line |
Australian considerations
Galley kitchens in food trucks must also comply with AS 1668.2 exhaust requirements and the local council mobile-food-premises code — see our food truck equipment checklist for the full mobile build.
Decision Framework: How to Pick the Best Commercial Kitchen Layout for Your Menu and Kitchen Space
The single best way to choose between assembly line, island, zone, open kitchen and galley is to score your venue against four variables: kitchen size, menu complexity, brigade size and service style.
| Variable | Assembly Line | Island | Zone | Open Kitchen | Galley |
|---|---|---|---|---|---|
| Kitchen floor area | 18–30 m² | 25–55 m² | 30–100 m² | 20–40 m² | 12–25 m² |
| Menu complexity | Low (fixed build) | Medium-High | Highest | Medium | Low-Medium |
| Brigade size at peak | 2–4 chefs | 4–8 chefs | 6–14 chefs | 3–6 chefs | 1–3 chefs |
| Service style | QSR / fast casual | Full service | Fine dining / hotel | Modern small-plates / theatre | Café / food truck |
| Covers per service | 200+ | 80–200 | 40–150 | 60–150 | 30–80 |
| Approx fit-out cost (AUD) | $40k–$120k | $80k–$200k | $150k–$400k+ | $80k–$220k | $25k–$70k |
| Best for | Burger / pizza / Mexican | Modern AU restaurants | Hatted dining, hotels | Izakaya / pizza / sushi | Café, food truck, ghost kitchen |
If two layouts both fit your variables, default to the one with the lower fit-out cost unless the more expensive layout unlocks marketing value (open kitchen) or menu range (zone).
Commercial Kitchen Layout Ideas for Small Commercial Kitchens
If you are spec-ing a small commercial kitchen with limited kitchen space, the following commercial kitchen layout ideas help squeeze the most out of every square metre:
- Stack vertically. Use overhead shelving and pot racks above the hot line and prep bench. The vertical envelope of any commercial kitchen is the cheapest storage there is.
- Combine appliances. A single combi steam oven replaces a convection oven, steamer and proof box — saving 1.2 m of bench. Pairing a salamander on a wall bracket above the range frees floor space.
- Pick a single-line galley. Two parallel rows of stations and equipment 1.2 m apart is the densest workable footprint for a small kitchen.
- Push prep off-peak. Small commercial kitchens cannot run dedicated prep and cooking stations at the same time — schedule prep before service so the same bench can pivot to plating during peak.
- Use a passthrough or undercounter dishwasher instead of a hood-type dishwasher. Lower clearance, smaller footprint, simpler ventilation.
Australian Compliance Tips for Commercial Kitchen Layouts
Whichever layout you pick, every Australian commercial kitchen must clear the same compliance gates:
- AS 4674 — Construction and fit-out of food premises. Sets out floor, wall and ceiling finishes; coving requirements; food contact surface specs; staff facility separation.
- AS 1668.1 + AS 1668.2 — Mechanical ventilation. Sizes exhaust canopies and make-up air. See our full commercial kitchen ventilation requirements guide.
- Grease trap sized to council code, registered with the local water authority (Sydney Water, Yarra Valley Water, Urban Utilities, depending on state).
- Air conditioning + make-up air designed alongside the exhaust system — never as an afterthought.
- Waste separation — at least three streams (general, recycle, organic) with dedicated bins inside the kitchen.
- DDA accessibility — accessible toilets, threshold ramps, and table heights.
- Food Safety Supervisor certification for at least one staff member per shift (NSW, ACT, Vic mandatory; rest of Australia best practice).
Pair this with our health inspection checklist and run a dry-run inspection two weeks before opening night.
Frequently Asked Questions About Commercial Kitchen Layout Design
What is the most common commercial kitchen layout in Australia?
The zone (station) layout is the most common commercial kitchen layout in mid-to-large Australian restaurants, because it scales from a 4-zone brigade up to a full Escoffier-style 8+ zone brigade as the venue grows. For café and small-restaurant fit-outs, the galley layout is the most common because it fits narrow shopfronts and minimises fit-out cost.
How much space do I need for a commercial kitchen?
A practical floor area benchmark is 30–40 % of total venue area for the kitchen (kitchen, dish pit and storage combined). A 30-seat café needs about 15–20 m² of kitchen space; a 60-seat restaurant about 30–45 m²; a 100-seat venue about 60–90 m². The chosen layout shifts that range — galley is the most space-efficient, zone is the largest.
Which kitchen layout is best for a small restaurant?
For a small restaurant (≤30 seats), the galley layout is almost always the best choice. It fits narrow tenancies, keeps fit-out cost down, allows a single chef to run two lines solo, and minimises ventilation cost by sharing one canopy. Assembly-line is the alternative for fixed-menu fast-casual.
What is the Australian standard for commercial kitchen design?
AS 4674 governs the construction and fit-out of food premises (floor, wall, ceiling finishes, equipment specs, staff facility separation). AS 1668.2 governs mechanical ventilation and exhaust. Both apply to every commercial kitchen layout in Australia.
Can I change my commercial kitchen layout later?
Yes, but it is expensive. Repositioning ductwork, gas lines, water lines, drains, exhaust canopies and fire suppression typically costs $30,000–$120,000 in a working kitchen, plus 4–8 weeks of closure. Pick the right layout up front — get a designer to walk you through workflow on the floor plan before any equipment is ordered.
Next Steps
If you are at the lease-signing or fit-out stage, run your floor plan against the decision framework above, then sense-check with an experienced commercial kitchen designer and a mechanical engineer for the ventilation calculations. Browse the commercial cooking equipment, commercial fridges, combi steam ovens and commercial dishwashers ranges to start your equipment list, or get in touch for a tailored layout-and-spec quote.
