This is a procedural building generator which uses blender's geometry nodes which allows you to customize various parameters of the generated building such as its length, width and number of floors.

I've also made it a kitbash system, which means that you can create your own building using custom parts (that matches the measurements, 2.0 x 1.2.) You can also use downloaded assets and photoscans to add more detail.

This was originally made in Blender v2.93 but has been updated to work efficiently in Blender v3.0. 

I am working on a version for 3.1.
