Beyond These Stars Best Buildings to Build First

Building a city on the back of a sentient space whale means every hex counts, and knowing the best buildings in Beyond These Stars is the difference between a thriving outpost and a colony that starves on Kewa's back. This survival city builder from the makers of Before We Leave rewards careful placement, smart adjacency bonuses, and a production chain that keeps your Peeps fed, housed, and working. Below, we break down the buildings that matter most at each stage of the game, how to place them for maximum efficiency, and which ones you should unlock first.

Why Building Choice Matters on Kewa

Beyond These Stars is not a sandbox where you can plop down anything anywhere. The land on Kewa is limited, and the game's official store page warns that the whale's ecosystem is fragile — over-exploit it and your habitat shrinks. That makes every building decision a trade-off between production, pollution, and space.

Buildings unlock through a single tech tree, but unlike most city builders, there are no research points to spend. You unlock a building by doing the prerequisite task — produce 5 wood with a wood cutter, smelt 10 iron ore, reach 30 population — then click the node in the tech tree. In practice, this means the best buildings are the ones that unlock the next tier of buildings fastest.

The Best Early-Game Buildings

Your first hour is about survival, not optimization. These four buildings form the backbone of any starting settlement.

Huts (Accommodation)

Huts are the single most important early building because Peeps will not work until they have a home. The Home Spaceship starts with 20 Peeps aboard, and they disembark only as you build accommodation. Huts also carry a powerful adjacency bonus: three nearby accommodation buildings grant +1 Peep slot, and five nearby grants +2.

Placement tip: Cluster huts in groups of three or five along a shared road. Player experience shows that a tight cluster of three huts is the most efficient early pattern — it maximizes the extra-slot bonus without wasting hexes on roads.

Potato Patches

Potatoes are your first food source, and energy is directly tied to food. A Peep who cannot eat after returning home ends the day at zero energy. Potato patches have two key adjacency effects:

• +4 potato storage for four nearby agriculture buildings
• +10% production when adjacent to a flooded tile
• −50% production for three or more nearby highly polluted tiles

Pair patches with a water pump and keep them away from your industrial zone.

Water Pumps

Water pumps must sit next to a flooded tile, so river placement is non-negotiable. One pump supports a surprising number of Peeps early on, but community reports note that every population increase should be matched with more drink production — running dry stalls energy just like running out of food.

Wood Cutters

Wood cutters have a working range — place one without forest in range and it produces nothing. Build at least two early, because wood feeds the sawmill, and the sawmill's wood waste byproduct is what powers your first generator. A common beginner mistake is under-building wood cutters and then wondering why planks are trickling in.

Mid-Game Powerhouses: Generators, Smelters, and Warehouses

Once survival is stable, the game shifts to production chains. These are the buildings that carry you into the mid-game.

Burner Generator

The Burner Generator is arguably the most important mid-game building. Your Home Spaceship cannot keep up with power consumption once you build a sawmill and smelter, and the generator burns wood waste (or raw wood) to produce power plus soot as a byproduct — soot later feeds your cleaner.

Its adjacency effect is a double-edged sword: it gains +50% speed for empty tiles nearby but produces more pollution when surrounded by buildings. Place it on the edge of your industrial zone, away from potato patches, and accept a little extra pollution for the speed.

Metal Smelter

The Metal Smelter is a multi-process building, meaning it runs one task at a time. You can configure it for steel or glass from the Work tab, but running both makes it slower than a dedicated setup. Community players recommend configuring for steel first — steel unlocks the Landscaper, which is the gateway to terraforming.

Warehouses

Warehouses store up to 10 unique resources and 320 total units, and you set the allocation manually. They solve the "no output space" notification that silently halts production — a problem that hits hard the moment you start terraforming, since lowering terrain generates hundreds of debris.

Recommended early allocation: 40 potatoes, 40 water, 40 wood, 20 tools, plus iron and stone as needed. Build a second warehouse before any large terraforming job.

Terraforming Buildings: The Landscaper and Cleaner

The Landscaper is the building that opens up the entire map. Large swaths of Kewa are uninhabitable until you spread atmosphere, and atmosphere comes from living trees, which need flowing water.

Landscaper

Place the Landscaper with the tiles blocking the river inside its working range, then use terraforming mode to lower terrain and release the water. Lowering terrain produces debris; raising it consumes debris. A single Landscaper holds 160 debris, so pair it with warehouse storage before big jobs.

Player experience suggests you can get creative here — some builders dump excess debris into a single tall spire or carve a staircase up a mountain to reach new forest and copper deposits. Both work, and both beat letting the job stall on full storage.

Cleaner and Toxic Tile Scraper

Pollution accumulates fast once generators and smelters are running. The Cleaner uses soot and water to maintain clean tiles, but it needs chemicals to handle toxic tiles. Until you unlock chemicals, the Toxic Tile Scraper is your stopgap — it physically scrapes polluted tiles and lets you rebuild. Buildings on toxic tiles simply stop functioning, so treat cleanup as urgent, not optional.

Decoration Buildings That Actually Pay Off

Decoration is not cosmetic in Beyond These Stars — it is a happiness engine. Unhappy Peeps move slower, and very unhappy Peeps refuse to work entirely.

Place decorations in the gaps between hut clusters. Because huts already want to be adjacent to each other, the leftover tiles are perfect for benches and meadows — you get happiness without spending extra road hexes.

Perk Synergies That Boost Your Best Buildings

Perk points come from tech tree unlocks, and a few of them dramatically change which buildings perform best.

• Move speed bonus with extra Peep slot — Peeps in buildings with extra slots move 30% faster when working. This makes clustered huts and warehouses with the "+1 Peep" adjacency far stronger.
• Extra energy from food — All basic food and drink give +10 energy, effectively stretching every potato patch.
• Reduced pollution from power buildings — Directly mitigates the Burner Generator's biggest downside.
• Landscaper move speed — Peeps working for a Landscaper move 20% faster, which shortens every terraforming job.

These perks are why the "best" building is rarely a single structure — it is a cluster of huts, a generator on the edge, and a landscaper with a warehouse behind it.

Common Building Mistakes to Avoid

Community discussion threads and gameplay footage highlight a few recurring pitfalls:

1. Ignoring the "no output space" notification. Production silently stops when storage fills. Build warehouses proactively.
2. Under-building wood cutters. Planks gate the Burner Generator, and the generator gates everything else.
3. Placing potato patches near industry. The −50% pollution penalty is brutal and easy to miss.
4. Skipping pause and priority controls. Pause non-essential production during power crunches, and set gathering buildings to high priority.
5. Terraforming without debris storage. A stalled Landscaper wastes Peep hours.
