Essential Tips for Planning the Layout of Your Restaurant Kitchen
- Zones first: A functional commercial kitchen is organised into defined zones — delivery, storage, prep, cooking, service and wash-up. Every layout decision should support the flow between them.
- Workflow direction: Food should move in one direction through the kitchen — from delivery and storage, through prep, to cooking, to plating and service. Cross-traffic between zones causes bottlenecks and contamination risks.
- Ventilation is non-negotiable: Every cooking appliance requires an extraction canopy sized to its heat and steam output. Undersized ventilation is the most common and most expensive mistake in kitchen fit-outs.
- Compliance before design: Australian food safety law under Standard 3.2.3 sets requirements for surfaces, drainage, lighting, handwashing and pest control. These must be designed in from the start, not retrofitted.
- Equipment placement affects energy costs: Refrigeration placed near cooking equipment works harder, uses more energy and fails sooner. Separate heat-producing and cold-storage equipment at the planning stage.
Planning a Commercial Kitchen Layout
A commercial kitchen layout is one of the most consequential decisions in a restaurant fit-out. Get it right and your kitchen runs efficiently from the first service — food moves smoothly from prep to pass, staff aren’t crossing paths, equipment is positioned where it’s needed, and compliance is built in. Get it wrong and you spend years working around a layout that fights you at every service.
This guide covers the principles that underpin every effective commercial kitchen layout: workflow zones, equipment placement, ventilation, compliance requirements and the decisions that are hardest to change once construction begins. It applies to new fit-outs, major renovations and equipment upgrades.
The Six Kitchen Zones
Every commercial kitchen — regardless of size or cuisine — operates through the same six functional zones. The layout’s job is to arrange these zones so that food moves through them in a logical sequence with minimal cross-traffic.
1. Delivery and Receiving
Where stock arrives and is checked. Should have direct access from a loading area and be positioned close to storage. Needs adequate space for deliveries without blocking kitchen workflow — a dedicated entry point separate from customer-facing areas is ideal.
2. Storage
Dry storage, refrigerated storage and frozen storage. Refrigeration must maintain food at 5°C or below under Australian Food Standards Code Standard 3.2.2. Position refrigeration away from cooking equipment — heat forces compressors to work harder, increasing energy costs and reducing equipment lifespan.
3. Food Preparation
Where raw ingredients are cleaned, cut, portioned and assembled before cooking. Requires adequate stainless steel bench space, a dedicated handwashing basin, and separation between raw meat, fish and produce prep to prevent cross-contamination.
4. Cooking Line
The primary cooking zone — stoves, ovens, fryers, grills, wok burners and other heat-producing equipment. The cooking line is the highest-traffic, highest-temperature zone in the kitchen and drives the ventilation specification for the entire fit-out.
5. Service and Plating
Where finished dishes are assembled, checked and passed to front-of-house. Should sit at the end of the cooking line with direct access to the pass. Hot holding equipment, heat lamps and plating benches belong here.
6. Wash-Up
Warewashing, pot washing and refuse disposal. Must be positioned away from food prep and cooking zones to prevent contamination. Requires plumbed hot and cold water, drainage, and correctly sized inlet and outlet benches for the dishwasher type specified.
Common Layout Configurations
The physical shape of your kitchen space will influence which layout configuration works best. The four most common configurations in Australian commercial kitchens are:
| Configuration | Best For | Key Consideration |
|---|---|---|
| Island Layout | Large square kitchens, hotel and institutional kitchens | Cooking equipment grouped in a central island with prep zones around the perimeter. Excellent visibility for kitchen managers but requires substantial floor area. |
| Assembly Line (Linear) | Quick-service restaurants, high-volume operations with repetitive menus | Equipment arranged in a straight line in the order of use. Maximises speed for a limited menu but less flexible for diverse cooking styles. |
| Zone Layout | Full-service restaurants with diverse menus | Separate stations for different cooking methods — grill station, sauté station, pastry section. Each station is self-contained with its own equipment and bench space. |
| Galley Layout | Narrow kitchens, food trucks, compact café kitchens | Equipment runs along two parallel walls. Efficient use of limited width but can cause congestion with multiple staff during peak service. |
Planning the Cooking Line
The cooking line is where the layout has the most direct impact on service speed and food quality. Equipment placement on the line should reflect how your menu actually works — the equipment used most frequently should be most accessible, and equipment used together should be adjacent.
Sequence of Equipment
A typical cooking line runs from cold storage and prep at one end through to the pass at the other. Equipment is positioned in the order it is used — for example, a char grill or stove adjacent to a pass-through to the sauce station, with a salamander or heat lamp above the pass. Commercial stoves and combi ovens typically anchor the line, with specialist equipment — char grills, deep fryers, wok burners — positioned according to menu requirements.
Underbench Refrigeration
Positioning under-bench fridges within the cooking line gives chefs immediate access to prepped ingredients without leaving the station. This is one of the highest-impact layout decisions for service speed — but these units must be rated for the ambient temperature of the cooking environment, as standard under-bench fridges will struggle to maintain temperature next to high-heat equipment.
Bench Space Between Equipment
Every cooking station needs adequate bench space on both sides for mise en place, plating and safe handling of hot equipment. A common mistake is specifying bench runs only between equipment groups — the result is chefs working without space during service. Build in at least 600mm of clear bench at each station.
Ventilation and Extraction
Ventilation is the single most commonly underspecified element in commercial kitchen fit-outs. Every cooking appliance produces heat, steam, grease-laden vapour and combustion gases — all of which must be captured and exhausted by a correctly sized canopy system.
Canopy Sizing
The canopy must extend beyond the cooking equipment on all sides — typically 150–200mm overhang — and be positioned at the correct height above the cooking surface. The required exhaust rate varies significantly by equipment type. Wok burners and high-output stock pot burners require substantially higher capture velocities than standard cooktops — a single canopy sized for a standard cooking line is frequently inadequate for a wok station.
Make-Up Air
For every volume of air exhausted, replacement air must be supplied. Without adequate make-up air, the kitchen operates under negative pressure — doors are difficult to open, exhaust performance is reduced and combustion appliances may not function correctly. Make-up air supply must be designed alongside exhaust, not as an afterthought.
Equipment Positioning for Ventilation
All heat-producing cooking equipment must be positioned directly under the extraction canopy. Equipment placed outside the canopy footprint is not captured — this is a compliance issue as well as a comfort and performance issue. Plan the canopy dimensions first, then fit equipment within it.
Refrigeration Placement
Refrigeration equipment works hardest — and fails soonest — when placed near heat sources. This applies to every type of refrigeration in the kitchen:
Refrigeration Placement Mistakes
- Adjacent to cooking equipment — radiant heat from ovens, fryers and grills raises the ambient temperature around refrigeration, forcing compressors to run continuously and reducing lifespan significantly
- In direct sunlight or near external walls — western and northern exposures in Australian kitchens can add significant heat load to refrigeration in those positions
- Blocking ventilation clearance — all refrigeration requires clearance around the condenser for heat dissipation; built-in units must be front-venting; rear-venting units need wall clearance
- Under-bench fridges in high-ambient environments — standard under-bench fridges are typically rated to 32°C ambient; a cooking line in a poorly ventilated kitchen can exceed this, causing temperature compliance failures
- Walk-in cool rooms adjacent to cooking lines — cool room compressors and insulated panels require protection from sustained radiant heat; position cool rooms on external or non-cooking walls where possible
Wash-Up Zone
The wash-up zone is frequently underplanned — allocated whatever space is left after the cooking line and prep areas are specified. This is a mistake. An undersized or poorly positioned wash-up zone creates a bottleneck that backs up the entire kitchen during service.
Key wash-up zone requirements:
- Dishwasher type matched to cover count — under-bench dishwashers suit up to 200 covers; pass-through machines handle 200–500 covers; conveyor machines are required for 500+ covers. See our commercial dishwasher buying guide for full guidance.
- Inlet and outlet benches — pass-through and conveyor dishwashers require correctly sized inlet and outlet benches; these must be specified and installed alongside the machine
- Separate pre-rinse area — a pre-rinse sink and spray arm upstream of the dishwasher reduces cycle contamination and improves wash results
- Pot wash station — large pots, trays and equipment that won’t fit in the dishwasher need a dedicated pot wash sink or pot washer with adequate bench space on both sides
- Refuse and recycling — bin storage must be positioned within the wash-up zone but away from food prep areas; compliant waste management is a food safety requirement under Standard 3.2.3
Australian Food Safety Compliance
Handwashing
Dedicated handwashing basins — separate from food prep and dishwashing sinks — are required in all areas where food handlers work. A single basin in the prep zone is not sufficient for a full kitchen; basins must be accessible to staff at the cooking line and in the wash-up zone without requiring them to leave their station.
Surfaces and Drainage
All wall and floor surfaces in food preparation and cooking areas must be smooth, impervious and cleanable. Grout lines, raw concrete and porous materials are not compliant. Floor drainage must be adequate for cleaning — falls to floor wastes should be incorporated at the design stage, not cut into an existing floor after fit-out.
Lighting
Minimum illumination levels are specified under Standard 3.2.3. Prep and cooking surfaces require higher illumination than storage areas. Lighting must also be positioned to avoid shadows over work surfaces — a common issue in kitchens where overhead lights are positioned above the canopy rather than in front of it.
Common Layout Mistakes
Avoid These
- No single workflow direction — a layout without a clear flow from delivery through to service creates cross-traffic, slows service and increases contamination risk
- Undersized ventilation — the most expensive mistake to fix after fit-out; always specify ventilation to AS 1668.2 and have it reviewed by a mechanical services engineer before construction
- Refrigeration adjacent to cooking equipment — raises ambient temperature around refrigeration, increases energy consumption and shortens equipment lifespan
- Insufficient bench space at stations — staff need clear bench space on both sides of cooking equipment; specifying benches only between equipment groups leaves stations without working space
- Wash-up zone underspecified — undersized dishwash benches and incorrect machine type for cover count creates service bottlenecks; specify wash-up zone to peak cover requirements
- Compliance retrofitted — handwashing basins, drainage falls, surface materials and lighting specified to Standard 3.2.3 must be designed in from the start; retrofitting is significantly more expensive
- No growth allowance — a layout that exactly fits current requirements leaves no room for menu expansion or volume growth; build in flexibility at the planning stage
Frequently Asked Questions
What is the most important principle in commercial kitchen layout?
Workflow direction. Food should move in one direction through the kitchen — from delivery and storage, through prep, to cooking, to service. Any layout that requires staff or food to move against this flow creates cross-traffic, increases contamination risk and slows service. Every other layout decision flows from this principle.
How much bench space do I need in a commercial kitchen?
A minimum of 600mm of clear bench space on each side of every cooking station is a practical baseline. Total bench requirements depend on your menu and the number of covers you produce — a kitchen running 200 covers per service needs significantly more prep bench than one running 50. Always specify more bench than you think you need; it is the most underspecified element in most kitchen fit-outs.
Does my commercial kitchen need council approval?
Yes. New commercial kitchen fit-outs and major renovations require development approval and a food premises inspection before trading. Your local council food safety team will assess compliance with Food Standards Code Standard 3.2.3 covering surfaces, drainage, ventilation, lighting and handwashing. Engage your council early in the planning process — requirements vary by jurisdiction.
How close can refrigeration be to cooking equipment?
As a practical rule, maintain at least 500mm separation between heat-producing cooking equipment and any refrigeration unit. Under-bench fridges built into a cooking line must be rated for the ambient temperature of that environment. Manufacturer specifications will state the maximum ambient operating temperature — confirm this matches your kitchen conditions before specifying.
What ventilation standard applies to commercial kitchens in Australia?
AS 1668.2 governs mechanical air handling and ventilation in commercial kitchens. It sets requirements for exhaust rates, make-up air supply, canopy dimensions and positioning. Compliance is assessed as part of the building approval process. Engage a licensed mechanical services engineer to design your ventilation system — undersized ventilation is the most expensive mistake to fix after fit-out.
Should I buy new or used commercial kitchen equipment?
New equipment is recommended for most categories — particularly refrigeration, dishwashers and cooking appliances. New equipment carries a manufacturer warranty, meets current energy efficiency and compliance standards, and has a known service history. Used equipment can represent value in specific categories — particularly heavy stainless steel items like benches, shelving and storage — but should always be inspected by a technician before purchase.
