Better Building Plus - Blueprints, Renovations and Functional Buildings for Project Zomboid

Better Building Plus lets you design buildings before construction, renovate existing houses and reproduce captured structures elsewhere.

Completed projects register as proper buildings with rooms, supporting vanilla-style wall and roof cutaways, indoor checks, utility connections, light switches and appliances.

The mod is a work in progress. Back up your save before installing.

From blueprint to building

1. Find a blank blueprint or craft one using four sheets of paper or graph paper and tape or glue.
2. With a pen in your inventory, right-click it to plan a building, renovate an existing one or load a template.
3. Draw rooms and place floors, walls, doors, windows, stairs, roofs, furniture and appliances.
4. Save and name the plan, then place its construction site.
5. Right-click the site and select Work on building.

Your character builds piece by piece while materials and tools are available. Put supplies in nearby containers so they can collect more automatically.

Planning tools

The catalog contains almost every vanilla tile, organized by style and color, with search, filters and building kits.

Planning features include:

• Transparent or solid previews.
• Floor-by-floor editing, room outlines and visibility controls.
• Basements excavated with a shovel before construction.
• Automatic roof suggestions and placement.
• A rug-building tool.
• Pipette, eraser, Ctrl+Z / Ctrl+Y and favorites on 1-9.

Carpentry unlocks more components, while Electrical supports wiring progression. Building magazines and studying existing objects provide additional unlocks. Progression is enabled for single-player by default and can be disabled.

Multiplayer and templates

Several players can work on one construction site simultaneously. Building templates can be transferred between single-player and multiplayer by copying their files.

Capturing existing buildings requires admin access in multiplayer or debug mode in single-player, using RC Structures before loading the capture through a blueprint.

Renovation files are stored locally and must be uploaded to the server for players who need them.

Construction settings

Easy Build completes a whole plan in one action but still consumes materials. Build cheat separately permits placement without material costs.

Server settings can restrict blueprint use to admins, control progression and allow building disassembly. Disassembly is disabled by default; its default material refund is 50% when enabled.

Requirements, saves and limitations

Requires RC’s Structures Framework 1.6.0 or newer.

Safe to add to an existing save. The first load takes approximately 20 extra seconds while the catalog initializes.

Removing the mod is not recommended. Buildings remain but lose room functionality, including indoor checks and lighting/cutaway behavior, until it is restored. Blueprints and magazines disappear.

Strict server movement anti-cheat may flag walking on unbuilt upper floors in Solid preview.

Modification or extension requires the original creator’s permission and attribution.
