A community kitchen is laid out as a one-way chain of zones, storage, prep, cooking, serving, eating and washing, so raw food never crosses the path of cooked food or dirty dishes. For a community of 100 the building should be at least 600-800 square feet, with each zone given its own floor area before construction starts.
Kitchen layout is the arrangement of storage, preparation, cooking, serving and washing areas so that food, people and waste move along separate, predictable routes.
The Layout Is Decided Before The First Pot Is Bought
Feeding a community is closer to running a small workshop than to scaling up a home kitchen. A badly placed sink or a door in the wrong wall cannot be fixed by working harder: it costs steps on every shift, and in a kitchen that serves everyone from one pot it can carry contamination to everyone at once. The parent guide gives the governing rule as one direction of travel: Storage, Prep, Cook, Serve, Eat, Wash, Storage.
This page is the orientation. The route itself is in One-Directional Flow Design, the individual rooms in Work Zones: Prep, Cook, Serve, Wash, and how the plan changes with headcount in Scaling for 30 vs 100 vs 150 People.
What The Plan Has To Contain
The parent guide sizes six zones for a community of 100:
| Zone | Floor area (sq ft) |
|---|---|
| Dry storage | 80-100 |
| Prep | 150-200 |
| Cooking | 200-250 |
| Serving | 80-100 |
| Dining | 400-600 (may be a separate building or outdoors) |
| Wash station | 80-100 |
The five working zones, leaving out dining, add up to 590-750 sq ft (80 + 150 + 200 + 80 + 80 = 590 at the low end; 100 + 200 + 250 + 100 + 100 = 750 at the high end). That sum is this page’s arithmetic, not a figure in the parent guide, but it sits inside the guide’s 600-800 sq ft for the building, which is a useful check that the zone sizes and the building size agree.
Method: Plan On Paper First
Step 1: Draw the route as a line. Mark where raw food enters and where finished dishes leave. Every other decision hangs off those two points.
Step 2: Give each zone its floor area from the table, then place the zones along the route in order. If a zone has to be smaller, shrink dining first; it can move outdoors or to another building.
Step 3: Put the heat on an outer wall where the chimney or hood can vent straight out, with the wash station near the water supply and the hot-water fire.
Step 4: Walk the plan with a pot. Trace the path of a full cauldron from the stove to the serving counter and of a tray of dirty bowls from dining to the sink. If either path crosses prep or storage, move something.
Common Mistakes
- Putting dining and wash against the storage door. Dirty dishes then travel back through the clean end of the building.
- Sizing the cooking zone for the cooks and forgetting the pots. Large vessels, wood storage for the day and room to stir are what use the floor.
- Leaving the wash station to the end. It needs the hot water and a drain that does not run back through prep.
Safety
A wood-fired kitchen is a fire and carbon-monoxide hazard before it is a layout problem
Put every stove and oven where smoke and exhaust leave the building through a chimney or hood, never into the working zone. Carbon monoxide has almost the same density as air, so it mixes through the whole room rather than settling low or rising to the ceiling; a sleepy or headachy cook is a warning to open the room and get outside (Carbon Monoxide Risks). Keep wood stores and straw away from the cooking zone and keep the aisles around hot vessels clear.
