Blueprint Library

Overview

The Blueprint Library is a system for saving, sharing, and downloading complete building designs. After spending hours constructing a house, players can convert it into a blueprint that preserves the entire structure, every piece of furniture, and all decoration choices. That blueprint can then be reused in the same save, carried to a new save file, or shared with other players.

This is separate from crafting blueprints, which are item schematics that unlock the ability to build specific tools, weapons, stations, and furniture. Crafting blueprints are permanent recipe unlocks. The Blueprint Library deals with architectural plans for entire buildings.

What gets saved

When you convert a building into a blueprint, the following elements are stored:

Essentially, the blueprint captures everything about a finished building so it can be recreated identically.

Saving a blueprint

Once you finish a build, you can save it as a blueprint through the building interface. The saved design becomes permanently available in your Blueprint Library. This works across save files, so a house you built in one playthrough can be brought back in a fresh start without rebuilding from scratch.

The developers specifically called this out as a feature for players who invest a lot of time in their builds: "spending hours creating the perfect home won't go to waste once starting a new savefile, but instead, it can be iterated on and brought back for consecutive playthroughs."

Sharing with other players

Blueprints can be shared through the Blueprint Library for other players to browse, download, and use. Downloaded designs can be edited and modified after placement, so they work as starting points rather than locked templates. When multiplayer launches in June 2026, this system is expected to become more prominent as players visit each other's islands.

Official Blueprints

NPCs in the game also offer pre-designed "Official Blueprints" as rewards. These provide complete house designs that players can place directly or use as a foundation to customize. They are useful for players who want a solid starting layout without designing everything from scratch.

The eight preset house templates available in the building menu (including the "Floating Oasis" houseboat) function similarly: they show all required materials upfront and can be modified after placement.

Placing a blueprint

When you select a blueprint to place, the game shows you the full list of required materials before construction begins. All materials must be in your inventory to start. Building pieces consume resources on placement, the same as manual building.

Currently in Early Access, grass, rocks, and trees under a placed blueprint are not automatically cleared, so players may need to remove them manually. The developer confirmed that automatic ground clearing when placing blueprints is planned for a future update.

Tips

• Save blueprints before demolishing or remodeling. There is no undo, so having a backup means you can always revert.

• Downloaded blueprints from other players can be a good way to learn building techniques. Place one, enter build mode, and study how the structure is put together.

• Official Blueprints from NPCs are worth picking up even if you plan to build custom. They come with curated decoration sets that can give you ideas for room layouts.

• Material costs for blueprints can be high. Check the requirements list before committing, especially for larger designs that need hundreds of stone or wood.
