This is a collection of building facades as I imagine existed in late middle aged town.
The models are only partially textured for different reasons:
Allow the user greater flexibility in using textures of their own choosing
Flexibility in combining different facades with different gables.
The untextured parts are intended (imho) to be textured using image textures.
Good quality images, which are compatible with the CC-0 license are hard to come by.
The download also contains some reference images so you can picture my intents. More details can be found in the README.txt inside the blend file.
