Valheim Floor Plan
Build structures in Valheim from pre-designed floor plans.
This package includes two components:
- ValheimFloorPlan mod — a BepInEx plugin that reads
.vfp plan files and builds them in-game.
- Valheim Floor Plan Designer — a browser-based app (included) for creating and editing
.vfp plan files.
Included in this package:
- The mod DLL (installed automatically under
BepInEx/plugins)
- The Designer web app (
BepInEx/plugins/ValheimFloorPlan/Designer/)
- Sample
.vfp plans to get started immediately
Creating Floor Plans
- Open the Designer and create or edit a plan.
- Save/export a
.vfp file.
- Point the mod config
FloorPlanFile to that .vfp file.
- In game, press the build hotkey (default F8) and place the design. A terrain snapshot is taken automatically before placement.
- To undo, press the undo hotkey (default F9). This removes all placed building pieces and restores the terrain to the snapshot.
IMPORTANT: Terrain can only be restored within the current session — if you leave the area or reload, the terrain snapshot is lost. Building pieces can be undone across sessions because they are tagged as built by Valheim Floor Plan.
Sample Plans
The samples/ folder contains ready-to-use .vfp examples:
samples/myfloorplan4x4.vfpsamples/myfloorplan8x8.vfpsamples/myfloorplan12x12.vfpsamples/myfloorplan16x16.vfpsamples/myfloorplan20x20.vfpsamples/myfloorplan24x24.vfpsamples/myfloorplan28x28.vfp

Notes
.vfp is the contract between the Designer and the mod.- Keep the format stable when changing either project.
- If you evolve the format, update both parser and exporter together.
