We recently released a prototype building generator which can be found here:
It allows you to create different sized buildings from small homes to large office blocks with potentially thousands of variations, all at the click of a button. We don't create interiors right now, but have received lots of interest for the feature to be added.
As the tool is still only a prototype we are looking for general feedback, bugs and ideas for features in a future complete tool. We will be using this devlog as a way to highlight interesting challenges we come across, share tips and of course some cool procedural buildings!
