Many varieties of homes such as log cabins, single story homes, and double story homes. Double story homes are a little over 20mm high. Also includes a church and a stable. Initial design of these buildings was to create small but flexible dioramas that can be placed on the gaming table to get a 3-D layout of a town without having to place 28mm buildings and filling up the whole table with the town. This allows gaming players to determine strategy in the town which can then be localized in the game at 28mm size.
