"Sears Catalog Homes (sold under the Sears Modern Homes name) were catalog and kit houses sold primarily through mail order by Sears, Roebuck and Company, a American retailer. Sears reported that more than 70,000 of these homes were sold in North America between 1908 and 1940. More than 370 different home designs in a wide range of architectural styles and sizes were offered over the program's 32-year history. Sears homes can be found across the continental United States. While sold primarily to East Coast and Midwest states, Sears homes have been located as far south as Florida as far north as Alaska and as far west as California. A handful of Sears homes have been identified in Canada. Elgin, Illinois (a city approximately 35 miles WNW of Chicago) has the largest known collection of Sears homes in one community with more than 200 identified houses from Sears."

There is one house for each level so you can use this as a theme. They all fit on a 2x2 grid.

Enjoy!
