Procedural Building Generator Addon for Blender - Low Poly Building Generator
Good to know
Very large floor/bay counts make heavy meshes - lower them while dragging sliders.
The building comes with procedural materials (facade, glass, roof) that you can recolor in the Color, Material & Texture panel; no image textures or UV unwrapping are needed.
Use Ctrl+Z to undo. Saving your .blend file keeps everything the add-on created; the add-on does not need to be installed to open the file, although you will need it to keep editing live.
