With this alternative version of the small building you can create even more variety!
The first combination is along the long side of the larger building. But of course you can also combine it along the short side.

If you also use mirrored versions of the L-shape, you can assemble a handful of symmetrical and asymmetrical layouts.
I am printing these houses with full wood textures because that is how I saw them most during research, but I still have the clay base texture in the files, so you can create and mix lots of looks with the print layers.
