The road is the layout
The most common mistake in SteamWorld Build is treating the layout as a question of where to put buildings. It is not. It is a question of what you lay under them.
Every building in the game — housing, factories, service buildings — must be connected by road, and that road network must ultimately reach the Train Station. A building outside the network does nothing. And it gets worse: each service building projects a blue-highlighted coverage radius, and only the housing that falls inside that radius receives the service. Housing outside it never upgrades, no matter how many service buildings you own.
So the single lever that changes your whole town is the road tier.
| Road | Service coverage | How you get it | Effect |
|---|---|---|---|
| Dirt Path | Low | Available from the start | Service buildings must sit almost on top of the houses they serve |
| Paved Road | Medium | Unlocks at Milestone 6 | Service reaches further; workers move faster |
| Maglev Road | High | Unlocked once you have upgraded an Aristobot into a Scientist | Houses do not need to be close to anything; workers move faster still |
Upgrading your roads is not a cosmetic late-game purchase. It is the thing that lets one service building cover a whole district instead of three houses. If your town feels cramped, the fix is almost always Maglev, not more buildings.
How to lay out the surface
1. Zone by citizen tier, not by function. Each resident tier wants different service buildings. Workers do not need a Casino — putting one next to Worker housing is a wasted building and a wasted upkeep. Give each tier its own district: Workers in theirs, Engineers in theirs, Aristobots in theirs, and put only the buildings that tier actually wants inside each.
2. Cluster the housing. Because coverage is a radius, scattered housing makes you build the same service building several times. Concentrated housing means fewer service buildings doing more work.
3. Use strip or grid roads between districts. It keeps the town readable and, more importantly, keeps every district reachable from the Train Station as you expand.
4. Understand what the housing upgrade chain is actually for. Housing is your only source of workers. Fill a house’s needs — both resource needs and service needs — and it upgrades, unlocking the higher tiers: Engineer, then Aristobot, then Scientist. Each tier pays more tax and unlocks more advanced buildings. This is the engine of the whole game, and it is why the road tier matters twice: it feeds the services that feed the upgrades.
5. Watch the workforce number, not the money. Every refinery needs Steambots from the tier it belongs to, and if you do not have enough, its production speed drops. The top toolbar shows your available workforce; if the number goes negative your production is already suffering, and the fix is more housing or better-satisfied housing — not more refineries.
How to lay out the mine
The mine is not a storage closet you dig out. It has its own layout rules, and breaking them costs you miners.
One big quarter per miner type. Mine camps are the underground equivalent of housing and they are what produce your miners. But production cards attach to the quarter, not to individual miners. Build three small quarters for the same miner type and you now have to feed three cards instead of one. Build one big quarter instead.
Leave big contiguous space before you place a workshop or armory. These buildings have a slot count that depends on how many tiles they occupy, and they only count as one building if they are connected. Place a workshop in a cramped pocket and you will not be able to expand it; place one that does not connect and the game creates a separate workshop. Pick your open ground first, then build into it.
Every blue area needs a support. As you dig deeper, the walls destabilise — the screen shakes and the game prompts you. Any area highlighted in blue must be covered with supports or you lose miners. Your miners will repair these themselves, but only as fast as they can, so if you are digging quickly you have to do it by hand.
Defences need roads. This is the one that quietly ruins runs. Guards, turrets and traps only function when they are connected to a road network, exactly like surface buildings. A turret in an unconnected pocket of the mine will sit there and do nothing while worms eat your miners.
The loop, and which direction it runs
The game has two halves, and the direction of the dependency flips.
Early: the surface funds the underground. Your town’s refineries produce what you need to dig, and you use surface resources to push the mine deeper.
Late: the underground funds the surface. Oil, water and ancient technology come from deeper floors, and those are what drive your advanced surface production. By the end you are not building a town with a mine attached — you are running a mine with a town attached.
Two practical notes that follow from this:
- Trade at the Train Station for the building upgrade items you cannot make yourself. Buildings generally have one to three enhancement slots that raise output, capacity or efficiency, and the station is where you get the items to fill them.
- Refineries have a percentage readout when you place them, showing how much of the deposit they can extract from that spot. Place them on the high numbers or you will be running a building at a fraction of its output forever.
Which map to pick
If you want space, pick Giddy-Up Gorge. It has the most open area and the fewest unremovable objects. It is also thick with trees, which matters more than it sounds: logs are in consistently high demand, and the Forester building needs them.
Fossil Park is the trap. It looks interesting and it is a poor fit for both foresters and raw space. If your plan involves a Forester, do not start here.
Where to go next
The three things players get wrong after the layout is fine are all counter-intuitive in the same way — the obvious fix does nothing:
- Your storage cap is 50 per good and building more warehouses does not raise it — see how to increase storage.
- Money comes from satisfaction, not production — the same Worker house pays five times as much once it is full — see how to make money.
- Granite blocks your dig until you have the right miners for it — see granite.
