Most of the houses are made by Musket Miniatures, http://www.musketminiatures.com/, which I think are the best available and fit many FOW size stands. They are somewhat expensive and do require a fair amount of effort to paint well. This pays off, but given my painting speed, is a small problem.
Other buildings are from Crescent Root, http://crescent-root.com/,
which are very good and come painted. Alas, this manufacturer is currently in production limbo and thus the buildings aren't available, whether I could afford them or not. Perhaps this is just as well.
I just found a new German company,Najewitz Modellbaushop, http://www.shop-021.de/shop-najemo.html, which makes Normandy row houses. These look very nice and I ordered a set of seven to see how they work out for this scenario. I am not sure how well you can put stands inside of the buildings, which makes the Musket Miniatures buildings so attractive. After I get these I will have to compare and contrast the pros and cons of all the various manufacturers. Anyway, back to the paint mines.
Another view on the town. The buildings in the center foreground are from Miniature Building Authority, http://www.miniaturebuildingauthority.com/. These look nice, and can be disassembled to reveal ruins, but have little space for normal infantry stands to hide in.
