Building Architect

Building Architect is a fully modular exterior building generator designed for artists, level designers, and technical creators who want fast, flexible, and reliable procedural architecture inside Unity.

With a clean and intuitive workflow, you can generate complete buildings — including walls, floors, facades, sloped roofs, flat roofs, and roof props in a simple click. 

Every change updates instantly in the editor, making iteration fast and enjoyable.

The system is built around a robust modular architecture: each building is assembled from interchangeable prefabs, allowing you to plug in your own assets, materials, and styles. Whether you're creating realistic cities, stylized environments, or prototype layouts, Building Architect adapts to your pipeline.

Key Features

• procedural generation Buildings Generate instantly floors, roof types, or design settings in 1 clic.
• Modular prefab‑based architecture Plug in your own wall modules, windows, doors, roof tiles, and props.
• Complete roof systemSloped roofs with multi‑row logic
  Flat roofs with edge and center modules
  Fully functional roof prop placement for both modes
• Facade generation Automatic placement of windows, doors, shops, and decorative elements with symmetry options.
• Captured facade plans Lock and reuse facade layouts across floors or entire buildings.
• Artist‑friendly controls Width, length, floors, symmetry, roof mode, and design presets — all editable in realtime.
• Clean hierarchy & optimized structure Generated buildings are organized, readable, and ready for further editing or export.

Use Cases

• Open‑world cities
• Stylized towns and villages
• Prototyping and level blockouts
• Architectural visualization
• Procedural content tools
• Game‑ready modular environments

Building Architect gives you the speed of procedural generation with the control of handcrafted assets — a perfect balance for modern Unity workflows

Performance‑ready architecture:

Generated buildings follow a clean, modular hierarchy that works seamlessly with Unity’s occlusion culling, frustum culling, and LOD systems. Whether you use Unity’s built‑in tools or a custom optimization pipeline, Building Architect integrates smoothly into performance‑critical environments such as open‑world cities or large‑scale levels.
