Commercial kitchen layout design: a practical guide

A commercial kitchen layout decides how safely and smoothly a team can work during service. Good layout design follows the food, keeps clean and dirty work apart and gives staff room to move. This article sets out the principles we use when generating concept layouts, and the questions to settle before you move into detailed drawings.

Start with the menu and the flow of food

Every layout begins with the menu. A menu built on grilled proteins needs a strong hot line and plenty of cold storage nearby; a bakery café needs ovens, proving space and long preparation benches; a takeaway needs a fast route from the cooking line to the collection point. Write down the main dishes, the expected covers or orders at peak, and the equipment the menu depends on.

Then map the flow: goods in, storage, preparation, cooking, holding, service and wash-up. Food should move in one direction wherever possible, so that raw ingredients do not cross paths with finished plates and dirty returns do not pass through clean preparation areas.

Choose a layout pattern

Most commercial kitchens use one of a handful of patterns:

• Assembly line – stations arranged in sequence along one or two walls, common in high-volume and quick-service kitchens.
• Island – the cooking equipment sits in the centre under a central canopy, with preparation and storage around the walls.
• Zone – separate areas for each activity, useful for larger restaurants, hotels and production kitchens.
• Galley – two parallel lines with an aisle between them, ideal for narrow units.

Our guide to restaurant kitchen layouts compares these patterns with diagrams.

Clearances and circulation

Staff need space to work and pass each other safely, especially when carrying hot food. Our concept layouts aim for main aisles of around 1,200mm, with more space where two people regularly work back to back or where trolleys pass. Narrower aisles may be acceptable in small kitchens, but they should be a deliberate decision rather than an accident.

Plan at least two routes out of the kitchen where the building allows, keep exits unobstructed and make sure doors do not swing into busy working areas.

Extraction and services

Cooking equipment that produces heat, steam, grease or fumes normally sits under an extraction canopy. Grouping heat equipment on one line simplifies the canopy and duct design. Think early about gas, three-phase power, water supplies and floor drainage, because moving them later is expensive. See our guides on UK extraction and US hood requirements.

Hygiene separation

Provide hand-wash basins where food handlers work, separate from food and equipment sinks. Keep wash-up close to the service return but away from food preparation. Store chemicals separately from food. These points come up repeatedly in EHO and health department reviews.

A checklist for your concept

1. Menu, peak volume and equipment list agreed.
2. One-way flow from goods in to service, with clean and dirty routes separated.
3. Heat equipment grouped under a canopy.
4. Aisles wide enough for the team and for trolleys.
5. Hand-wash basins at each food handling area.
6. Two exits where possible, kept clear.
7. A defined service pass between kitchen and front of house.

Turning the principles into a concept

KitchenSpace Pro produces a measured 2D layout and matching 3D view from a brief or an uploaded drawing, with an equipment list and basic safety checks that flag common issues for review. Designers use it to compare options before CAD work (see how); owners use it to test a unit before signing a lease. Concepts are advisory: final sign-off rests with your local authority and qualified professionals.
