Zoning a settlement means sorting its activities into separate areas so that noisy, smoky, smelly or fire-prone work never sits beside homes, children and drinking water, while activities that depend on each other stay close. A settlement of 100-150 people is laid out in five zones: a communal core, a residential zone, an agricultural zone, an industrial zone for workshops, and a storage and utilities zone.
Part of Settlement Layout for 150 People
Zoning is the practice of giving each kind of activity its own area of the settlement, placed by wind, slope, water and walking distance rather than by whichever plot is free first.
Separate What Clashes, Group What Cooperates
Two rules produce most of a good layout. First, separate incompatible activities: a forge throws sparks and noise, a livestock yard produces smell and runoff, a latrine produces pathogens, and a sleeping house or a well is damaged by all of them. Second, keep dependent activities close: gardens need daily tending so they belong next to homes, the kitchen belongs next to the water point, and the workshop needs a cart path to the fields.
The settlement-layout guide organizes 100-150 people into five zones. The sizes and distances below are that guide’s; each zone has its own article.
| Zone | What it holds | Rule from the layout guide |
|---|---|---|
| Communal core | Gathering hall, water point, plaza, medical station | Centre of the housing, 2-3 minutes’ walk from every home |
| Residential | 30-40 housing units in clusters | At least 5 m between buildings |
| Agricultural | Gardens, fields, pasture, barns | Surrounds the housing; gardens closest |
| Industrial | Forge, carpentry, mill, processing | Downwind of homes, at least 30 m from the nearest house |
| Storage and utilities | Granaries, tanks, waste, salvage | Between fields and housing |
What You Need
- A contour map or at least a slope sketch — to know which way water, runoff and cold air move (Contour Mapping)
- A season of wind observations — the prevailing direction decides what is “downwind” (Prevailing Wind Patterns)
- The fixed water source — everything else is placed relative to it (Source Protection)
Method: Place The Fixed Things First
Step 1: Mark water, slope and wind. Draw the water source, the downhill direction and the prevailing wind on the plan. These do not move.
Step 2: Place the communal core. Put it at the centre of where the housing will be, so no home is more than 2-3 minutes from it. At an assumed walking speed of 5 km/h, about 83 m per minute, that is roughly 170-250 m.
Step 3: Place the housing around the core, then the fields outside the housing, with the intensive gardens nearest the homes.
Step 4: Place the workshops downwind of both housing and core, and the waste and sanitation works downhill of every water source.
Step 5: Leave one side open for growth, so the fields are not on every side of the settlement (Expansion Corridors).
Common Mistakes
- Building dense because it seems efficient — it multiplies fire spread, sanitation trouble and quarrels.
- Putting workshops upwind — one prevailing wind then carries smoke and noise through the whole settlement.
- Placing waste uphill or beside a well — contamination follows water downhill, and in fractured rock or limestone no setback distance is protection at all.
Safety
Fire and water contamination are the two zoning failures that kill
Fire spreads fastest between close combustible buildings, and the layout guide’s 5 m residential spacing assumes non-combustible walls; the fire guide doubles it for timber or thatch walls (Fire Prevention in Settlements). Keep latrines and animal pens at least 30 m from any water source in ordinary soil and further in gravel; the ground, not the number, decides the real distance.
