A shared kitchen with one large hearth can cook for 4-8 families, saving fuel because one fire cooks for many and saving building because it needs one chimney and one preparation area. For the 15-40 people those families contain, plan 22.5-80 m² of dining floor and 9-24 m of table, put the hearth behind a fire-resistant wall with its own flue, and keep it out of the sleeping rooms.
Part of Multi-Family Housing Design
A shared kitchen and dining area is a common cooking hearth and eating space serving several households in a multi-family building or cluster.
One Fire Cooks For Many, And Burns For Many
The multi-family guide recommends sharing the kitchen: a large hearth serving 4-8 families saves fuel (one fire cooks for many) and construction (one chimney, one preparation area), and it was common in historical communal living. The same fire is a single ignition point for every home that shares its roof, so the kitchen is both the biggest saving and the biggest fire risk in the building.
Worked Example: People, Dining Area, Table Length
Inputs: 4-8 families; 3.75-5 people per household (the layout guide’s 30-40 units for 150 people); dining allowance of 1.5-2.0 m² per person and 60 cm of table per person from Community Gathering Hall.
- People served: 4 × 3.75 = 15 to 8 × 5 = 40.
- Dining floor: 15 × 1.5 = 22.5 m² to 40 × 2.0 = 80 m².
- Table length for everyone at once: 15 × 0.6 = 9 m to 40 × 0.6 = 24 m.
If the dining floor is smaller than this, eat in sittings. The kitchen itself is extra: Community Kitchen Design and Operation gives 600-800 square feet (about 56-74 m²) for a community of 100, including its dining zone, with food moving one way from storage to preparation, cooking, serving, eating and washing.
What You Need
- A hearth or stove with a flue to the outside, not shared with any other fire
- A non-combustible hearth floor extending 40 cm in front and 20 cm to each side (fire guide)
- Water and a wash area
- A wall of masonry or earth between the kitchen and any sleeping space
Method
Step 1: Site the kitchen at one end or outside the main block, not between bedrooms.
Step 2: Build the hearth with the clearances the fire guide sets: a stove at least 40 cm from combustible walls, a chimney at least 5 cm from wood (Fire Prevention in Settlements).
Step 3: Plan the flow of food from raw to cooked to served so raw material never crosses finished dishes.
Step 4: Set a rota for fuel, cleaning and the evening banking of the fire (Community Roles).
Common Mistakes
- Putting the kitchen against a bedroom wall — noise, heat and smoke.
- One chimney shared by the kitchen and a neighbour’s stove.
- No ventilation, so smoke fills the room and carbon monoxide builds up.
Safety
Fire and carbon monoxide at the heart of the building
Most building fires start at the stove or chimney. Keep the flue clean (at least once a year), keep fuel stored 10 m from buildings, and ventilate with an inlet and an outlet. A banked fire left overnight in a room with sleepers is a carbon monoxide risk. Wash hands and surfaces after raw meat, and give children no access to the hearth.
