Biome Blueprints

353 ready-made house and base designs for PlanBuild, sorted by biome and revealed as you find the materials they are made of.

Open your Blueprint Rune and there is a tab for each biome, plus one for furniture and one for

ornaments. Every tab is ordered cheapest first. Pick a design, place it, and the ground under it

flattens to meet the floor.

What is in it

| Tab | Designs |

|---|---|

| Meadows | 31 |

| Black Forest | 33 |

| Swamp | 21 |

| Mountain | 16 |

| Plains | 42 |

| Mistlands | 33 |

| Ashlands | 89 |

| Ashlands II | 45 |

| Furniture | 24 |

| Decoration | 19 |

Valheim draws 90 pieces per tab and quietly ignores the rest, so a biome with more designs than

that spills into a second tab rather than losing them.

78 are generated house designs — huts, cottages, longhouses, stilt houses, manors, great halls

and stone-founded villas, one set per biome.

275 are community builds by 89 builders, imported with their names and descriptions intact. See

Credits.

How it works

Designs unlock with your materials, the same way vanilla build pieces do. A design appears once

you have found what it is made of — so a Meadows cottage is there from the start, and a black marble

hall waits for the Mistlands. Nothing is hidden behind a config or a cheat.

Every design shows its full material list as item icons under the build menu, red where you are

short, exactly like any other piece.

The ground is flattened for you, but only where it needs it. Each design carries terrain

markers sized to its own footprint plus two floor tiles of clearance. Before placing, every marker

is measured against the ground beneath it: the ones over ground that already matches are dropped,

so a design put down on level ground — or on a floor inside a house — leaves the terrain alone

entirely. On a slope it levels the plot as you would expect, and a design half on a slope levels

only that half.

Nothing here needs another mod. Every design was checked against the game's own prefab list;

builds that needed furniture or building mods were left out rather than shipped half-built.

In the build menu

Every tab is ordered by size, smallest first. The first designs you see are the ones you can

realistically build; a 39,000-piece cathedral is at the end where it belongs. The piece count is

written on every design.

Mouse wheel moves through the designs. Q and E change tab — vanilla treats a scroll

notch as a tab change, which with this many tabs is very easy to do by accident.

Placing a design deselects it. Keeping one selected keeps its whole preview alive and drawn

every frame, on top of the plan you just placed, and nobody places the same base twice in a row.

Trees and rocks in the way flash red, and the design will not go down. Press place and

anything standing inside the design — trees, stumps, boulders — flashes red for ten seconds, and

placing is refused until they are cleared. Turn it off, or allow a second click to override it,

in the config below.

Removing a design you have placed

You do not have to take it apart piece by piece. PlanBuild's own Tools tab has this:

| Tool | What it does |

|---|---|

| Remove planned pieces | Hold to remove the whole blueprint at once, or hold for a radius |

| Objects | Delete pieces or Delete everything within a radius — works on structures you built directly |

| Edit blueprint | Edit or delete blueprints you have placed |

Performance, and low-end machines

The one expensive thing this mod does is the placement preview — the ghost that follows your

cursor. A 15,000-piece base means 15,000 pieces of ghost, and that is a lot to draw.

So the mod welds that preview into a handful of meshes. This is why a big design pauses for a

moment the first time you select it, and never again. That pause is the optimisation running, not

the mod hanging.

Once a design is down, three more things keep a large base affordable, all of them on by default

and all switchable in the settings below:

  • Small pieces do not cast shadow

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.
