I’m currently working on a package for the asset store which will contain 10 buildings. These are the first two:

The buildings are available in 4 sizes: 8m x 8m, 8m x 16m, 16m x 8m and 16m x 16m:

To use as less tris as possible, the buildings also exist in 6 layouts: front only, back only, front + left, front + left + right, all sides and front + back.

And 20+ color schemes can be selected: (more to come)
