It is a new procedural building generator based on blender geometry nodes. The generator allows you to create buildings with randomized assets in a few clicks, also ability to customize and specify the exact placement of assets, to choose the building material from the list, to edit and add new asset collections and materials.

The starting cube is equipped with all materials and geometry nodes, from which you can model any building you can imagine.

After modeling, the building should be UV unwrapped  to get the correct textures. It is highly recommended to use blender internal Magic UV addon (enabled in preferences) to get the best looking textures for your buildings.
