The short answer
The developer describes three construction tiers: Wood, Scrap and Quality Metal. They differ in durability and the warmth provided indoors. Wood is the starting tier; the blueprint tree unlocks later tiers. Exact construction costs are not verified here.
Match the tier to your current unlock
The December 2025 post gives broad areas, not map coordinates or guaranteed drops. Each tier is described as having basic and advanced versions. Do not interpret that as every piece being unlocked at the start.
| Tier | Announced material lead | What to check |
|---|---|---|
| Wood | Horizon and Woods | Starting wooden set and its available pieces |
| Scrap | House Camp and Solar fields | Required blueprint before a gathering trip |
| Quality Metal | Later regions; smelting Iron | Smelter access and the current conversion recipe |

Before gathering for an upgrade
This is a suggested verification workflow, not a measured recipe. If an upgrade is missing, separate a blueprint lock from a material shortage. Gathering more metal cannot prove that a locked blueprint will become available.
- Select the intended structure in the blueprint/build menu.
- Check that its tier and piece are unlocked.
- Copy the displayed requirements, then subtract materials already held.
- Gather the remaining amounts and confirm the completed piece in the world.

Treat warmth as a requirement
Higher tiers affect shelter durability and indoor warmth in the developer description. No numerical insulation values, heater radius or storm-safe layout has been supplied here. Before using an outpost as a return point, observe its actual warmth behavior in the build you play.
