Present United 3D - Procedural Modular Building Generator (Blender 5.1)

Create complete, highly detailed buildings in seconds – fully procedural, fully modular, and fully customisable.

This procedural building generator for Blender 5.1 uses a powerful Construction Script–style workflow with modular meshes to generate entire buildings, including exterior and interior layouts, from a single setup. Designed for rapid worldbuilding and environment creation, it lets you iterate fast while keeping full artistic control.

Key Features

  • Fully Procedural Building Generation
    Generate complete buildings automatically using modular parts – walls, floors, roofs, doors, windows, interiors and more.

  • Interior & Exterior Support
    Create believable interiors alongside façades, ideal for games, cinematics, archviz and concept art.

  • Modular by Design
    Use the included modules or create your own custom modules to expand the system endlessly. The generator adapts to your assets.

  • Style Switching
    Instantly swap between different architectural styles:

    • Clean modern buildings

    • Vintage / historic houses

    • Cyberpunk structures

    • Post‑apocalyptic ruins

  • Destruction & Damage Tools
    Apply destruction and decay functions to create war‑torn, abandoned or post‑nuclear environments with variation and realism.

  • Non‑Destructive Workflow
    All generation happens procedurally – tweak parameters, change modules or styles at any time without rebuilding from scratch.

  • Artist-Friendly Controls
    Designed for practicality and speed, not black‑box randomness. Every element can be refined, styled or overridden.

Perfect For

  • Game developers

  • Environment artists

  • Worldbuilding & level design

  • Cyberpunk & post‑apocalyptic scenes

  • Rapid prototyping and block‑outs

  • High‑detail renders and cinematics

Built natively for Blender 5.1, this tool scales from quick prototypes to production‑ready assets, giving you full control over structure, style and storytelling.

It is very nice template, really offers a lot of options and possibilities. However, I have to ask, as far as I can see, the building is basically rectangular in shape. I know that varying the shape of the base leads to a lot of complications, first of all, you need to have modules for each position, but I’m still interested in whether it is possible to implement more complicated rectangular shapes, L or H base, etc.?
