Just a quick update now that I've got the first proper building model done.

I'm still not 100% happy with the roof, but it's very close to done.

I can assure you it took quite some time to get this looking decent, mostly because I was experimenting with textures, things like how to make the bricks and the corrugations in the roof the right size compared to the people and how to arrange them so that they are interchangeable for all the different wall models. I've now created a "standard", so in future textures and models for the buildings at least should be quicker to create.
