Workshop & Forge Design
A settlement’s workshops are its manufacturing center—where raw materials become tools, building components, containers, and trade goods. Poorly designed workshops waste labor, create safety hazards, and limit what you can produce. Well-designed workshops multiply your community’s capabilities.
This guide covers layout principles for the three most critical workshop types: the smithy (metalworking), the carpentry shop, and the pottery studio. These can be separate buildings or zones within a larger workshop complex.
General Principles
Location within the settlement: Workshops produce noise, smoke, dust, and fire risk. Place them downwind from residential areas, at least 30 meters from sleeping quarters. Close to raw material storage (wood lot, ore/scrap metal, clay pit). Close to water for forge quenching and clay work.
Building orientation: Large doors or open walls should face away from prevailing wind (so wind doesn’t blow smoke and sparks into the work area) OR perpendicular to wind (for natural cross-ventilation). This depends on the specific workshop.
Floor: Earth or stone floors for fire safety. Never use wood floors in any shop with forge, kiln, or open flame. Packed earth is adequate; flagstone is superior. A compacted gravel floor drains well and provides stable footing.
Roof: High ceilings (3.5-4.5m minimum) for heat and smoke clearance. A clerestory gap (raised center ridge with ventilation opening) allows hot air and smoke to escape.
The Forge & Smithy
The smithy is the most demanding workshop to design because it combines extreme heat, heavy loads, toxic fumes, and fire risk in one building.
Layout
The forge is the center of the smithy. Everything else is arranged around it:
Forge placement: Against an exterior wall or in a corner with a chimney directly above. Never place the forge in the center of a building—smoke must have a clear path out. The chimney should be stone or brick (not wood) and extend above the roof peak.
Anvil placement: 1.5-2m from the forge, on the smith’s dominant-hand side. The anvil should be at knuckle height when the smith stands upright with arms at sides. Mount on a hardwood stump (oak, elm) set into the ground or on a heavy stone base. The stump absorbs vibration and reduces fatigue.
Workflow direction: Forge → anvil → slack tub (quench) → finishing area. This should flow in a natural sequence without backtracking. A right-handed smith typically has: forge on the left, anvil center, quench tub on the right.
Quench tank: A stone, metal, or lined wooden tub holding 40-80 liters of water, within arm’s reach of the anvil. Change the water when it becomes too hot (warm water quenches too slowly).
Fuel storage: Coal or charcoal stored in the smithy but away from the forge—at least 3 meters. Sparks can ignite fuel storage. Keep a day’s supply near the forge in a stone or metal bin; bulk storage outside or in a separate outbuilding.
Tool rack: Within arm’s reach of the anvil—hammers, tongs, punches, chisels, hardies. A thick wooden beam at waist height with hooks, or holes drilled for handles to slot into. The smith should be able to grab any tool without stepping away from the anvil.
Ventilation
The forge produces carbon monoxide (lethal), sulfur dioxide (from coal), and metal fumes. Ventilation is a life-safety issue.
Minimum: The forge chimney should create sufficient draft to pull fumes up and out. The hood above the forge should extend at least 30cm beyond the forge on all sides.
Additional: Open walls or large doors on the sides away from the chimney provide cross-ventilation. In cold weather, partial walls with adjustable shutters let you balance ventilation against heat retention.
Signs of poor ventilation: Headache, dizziness, nausea while working = carbon monoxide exposure. Stop work immediately and ventilate. This can kill.
The Carpentry Shop
Carpentry requires space, good light, and a solid workbench. It produces wood dust (fire and respiratory risk) but much less toxic fumes than metalworking.
Layout
Workbench: The centerpiece. Build it heavy and rigid—a wobbly bench wastes effort on every cut. Traditional design: 60-70cm wide, 180-250cm long, 80-90cm tall (elbow height when standing). Hardwood top at least 8cm thick. A front vise and tail vise (wooden screw mechanisms or wedge-based) hold workpieces.
Place the bench where it gets maximum natural light—near a large window or open wall. The worker should face the light source, not have it behind them (back-lighting creates shadows on the work).
Assembly area: Clear floor space (at least 3×3m) for assembling large items: door frames, furniture, carts. This area should be away from the workbench to prevent debris interference.
Lumber storage: Covered but ventilated space for drying and storing lumber. Green (fresh-cut) wood needs 6-12 months of air-drying before use. Stack lumber with spacer sticks (stickers) between layers for air circulation. Weight the top to prevent warping. See timber-harvesting for details.
Tool storage: Saws, chisels, planes, augers, drawknives—each should have a specific spot on a wall rack or in a tool chest. Tools left on the bench or floor get damaged and cause injuries.
Dust Management
Wood dust from sawing and planing accumulates and creates both fire and health hazards:
- Sweep daily. Store sweepings for fire starter or compost
- Keep any open flame (candle, oil lamp) away from active sawing areas
- If possible, do heavy sawing (rip-sawing, planing) in an open-air area outside the shop
The Pottery Studio
Pottery requires a wheel area (clean, dry), a clay preparation area (wet, messy), and a kiln (fire hazard). These three zones should be distinct.
Layout
Wheel and workstation: A potter’s wheel (kick wheel or hand-turned) needs a stable, level floor. Place near a window for light. A sturdy table nearby holds works in progress. Shelving for drying pieces should be out of traffic paths but accessible—greenware (unfired pottery) is fragile.
Clay preparation: This is messy. A separate area with a wedging table (a sturdy table with a plaster, stone, or concrete top for kneading clay), water access, and a place to store raw clay. Slop water and clay trimmings collect in a reclaim bucket.
Kiln: The kiln should be outside the main building or in a separate attached structure with its own roof but open sides. Kilns reach 900-1200°C and present serious fire risk. Place at least 5 meters from any combustible wall or roof. The kiln needs its own fuel storage (wood, charcoal) nearby.
Fire Safety for All Workshops
Workshops are the highest fire risk structures in a settlement. Design for fire containment from the start:
- Non-combustible walls between workshop zones and adjacent buildings. Stone, earthbag, or thick earth plaster over any framework
- Fire break — minimum 3m clear space between the workshop building and any other structure. 5m is better. See fire-prevention-settlements
- Water supply — a filled barrel or tank of at least 200 liters inside or immediately adjacent to any workshop with fire. This is for emergency suppression, not regular use
- Sand buckets — for metal fires and grease fires (water makes these worse). Keep 2-3 buckets of dry sand near the forge and kiln
- Exit routes — every workshop space should have at least two exits, on different walls. You must be able to get out even if the side nearest the fire is blocked
- No combustible storage in fire zones — keep finished wood products, oil, solvents, and cloth away from forge and kiln areas
Lighting
Workshops need abundant light. In a pre-electric world, natural light is your primary source.
- Large windows and open walls on the south and east sides (morning light for early work)
- Clerestory windows — a raised center section of roof with windows. Provides even, shadowless light across the interior
- Light-colored interior walls — whitewashed or lime-plastered walls reflect and distribute light
- Task lighting — oil lamps or candles in protected holders (glass chimney lamps are safest) for detail work. Position to illuminate the work, not the worker’s eyes
- Reflectors — salvaged mirrors or polished metal behind lamps double their effective light output
Multi-Workshop Complex
As a settlement grows, workshops often cluster into a craft district. Organize this intentionally:
- Shared courtyard — a central open work area for large projects, communal tool maintenance, and social interaction between craftspeople
- Shared fuel storage — one well-managed charcoal and wood supply serving forge and kiln
- Water system — a shared gravity-fed-plumbing branch serving all workshops
- Noise zoning — the smithy is the loudest. Place it at one end of the complex, with quieter workshops (pottery, leatherwork) at the other end
