This is a very, very old building. It dates back to when we still all gamed at Sunrise Hobbies & Games, now closed. That's roughly the time of 1st edition warhammer. It's been used in Zombietown as well as our Post Apocalyptic games, as it makes a better "Retreat" than even Bullock's house. The shell is the Plasicville L-shaped ranch house. It is often out-of-production, but is re-released on an infrequent basis. It was spray painted with Testors Military Flats Afrika Mustard color, which is a fine dark tan, and dry-brushed with lighter tans. The roof was spray painted with Krylon Ultra-Flat black (my preferred black primer) and dry-brushed with tans.
Rural Ranch
Here are the other buildings to this series. The log cabin did not have a chimney, and this was constructed with some extra epoxy putty I had lying around (and it was an awful lot of old putty). The buildings were primered in dark brown, and dry-brushed their various colors. That's it - very basic. Both do not have any interiors.
The interior was left very basic and unfinished, to allow furnishing for multiple periods and genres.
One of the best material available to make corrugated tin shacks and roofs comes from the boxes of light bulbs. Real light bulbs, of course, not their twirled-neon "energy saving" cousins. Hoard this material while it is still available. You will use it again and again in your modelling. Once it's all gone, you can buy corrugated cardboard at craft stores, but the corrugations are a bit large for modelling purposes. It can be painted light colors or dark. Go to the older industrial part of your town and take a look at how those old factories and outbuildings look - that'll give you something to shoot for.
The last building in this series is a fine example of using childrens' toys to suit your gaming needs. This is actually an ERTL "farm toys" ranch house. It come in pieces and assembles quite well. This one was spray painted with Testors Military Flats Afrika Mustard color, then washed with a blackish-brown paint. It was then dry-brushed with various tans to achieve the above results.
Once again, light bulb boxes were used to simulate corrugated tin sheets, this time for the top and porch roofs. This particular variant was painted a dark steel color and then dry-brushed a lighter silver. The result is something you might see in the bayou. Indeed, this was "Fast Eddie the River Pirate's" hideout in one of our Post-Apocalyptic games, and has been used in Zombietown as well.
The interior was left rather plain to allow more tactical variation during games. The foam-core floors had printed out pieces of paper pasted on to them to look at least passable.
