Here is the demo of the Building Generators,

Made this video with the Building Generator that i created,

Made this geometry nodes buidling generator,

it has 2 unique buildings, it's a kind of classical building i would say, and few more buildings that is mix and matched the assets,

It has 27 Randomly generating store names,

The width and depth of the building can be adjusted separately,

It has 3 layers of floors, 

1. Ground floor which has storefronts with auto randomizing store names, it also has 1 entrance,
2. It has first set of floors, which you can adjust the number of floors separately,
3. It also has second set of floors which you can also adjust the height separately, 
4. It also has top trim and another building has to rooftop, it's static you can not adjust the height,

Every asset  is made in the same dimension 4.04 X 4.66 so you can almost mix and match the assets of other buildings, the option to add your own assets is not included for now, but you can model in the same dimensions and can add your own assets to the respective folders, in future updates i will include the easy way of adding your own assets,

thank you for your time.
