Assemble modular buildings fast, inside the Unreal Editor.

HausTools is a simple, user-friendly editor toolset designed to make constructing buildings from authored modular assets easy. Choose from our PropHaus Compatible Packs or import your own custom meshes!

Documentation | Showcase Video | Discord

It works as a grid snapping distribution system for modular building meshes. You draw the shape of your building and HausTools places the right piece at every position. Everything snaps perfectly together, so the pieces line up exactly how you design your building.

What you draw first is a plain blue blockout. Clad it with real static meshes from your catalog to get the look for your finished building.

Bake the finished building into plain Unreal assets that perform well: Level Instances, instanced static meshes or plain actors that share static meshes across buildings. HausTools is an editor-only plugin, so a baked building output no longer requires it.

Features:

• Compatible PropHaus packs come with a complete catalog, with nothing to set up!

• BasePack Template: shows you exactly what you need for your own custom meshes, includes a Blender file for reference

• Bake: output your buildings as Level instances, Instanced static meshes or plain actors to be used outside of HausTools.

• Walls and Rooms: of any length and size, square or at 45 degrees, joined cleanly at corners and junctions

• Doors and windows: placement tool using authored static meshes to create openings

• Clad: use real modular building static meshes that HausTools distributes efficiently along your wall runs to be instanced by the output to keep your building's performance optimal

• Floors and ceilings: that fill the rooms your walls enclose procedurally

• Roofs: powerful easy to use tool that includes five roof forms fitted to the room in one click, pitched from 5 to 75 degrees. Overhang, gutters and downspouts. All overlapping roofs merge into one clean cut piece with interiors

• Stairs: that fit themselves to the storey height, cut their own stairwell and carry rails, stringers and under-stair walls. Change their shape and create split level landings intuitively

• Platforms and decks: that raise the building's foundation to meet them

• Fences: to rail a porch, a balcony or a stairwell

• Multiple storeys: add as many as you'd like and edit them one level at a time

• Materials and painting: every wall face, roof part, floor, ceiling and pack piece can be painted on its own

• Dollhouse: cutout view mode to look behind walls on the storey you have selected

• Grid snapping: on everything you place

Additional Information:

• BasePack: a plain blockout pack with a full catalog, is included, so you can clad from the start. It is also a template for building your own pack from meshes you already have: See Building Your Own Pack Documentation

• An example map with a BasePack house is included

• PropHaus packs are sold separately on Fab: See Compatible Packs

• Editor only: there is no runtime or in-game builder. Houses save with the level, bake the buildings into Level Instances, Instanced Static Meshes or plain actors

• Works with Unreal Engine 5.7 and 5.8

• Requires the MeshModelingToolset and GeometryProcessing engine plugins, which ship with Unreal Engine and enable automatically
