Today's Chicago Tribune has a profile of our town, Lombard, and the article mentions that there are a large number of kit homes here. Back in the first half of the 19th century it was not unusual to order your house out of a catalog. The manufacturer would then ship you the blue prints and all the supplies (as much as two train cars full!) to build it yourself.
Some of the features of my house (particularly the amateurish job done on installing the walls, lol) have made me wonder if it was built from a kit. But our house dates from 1949 and since Sears stopped selling kits in 1940 (and they were the only manufacturers of kit homes I had heard of) I figured our house couldn't be one. However, this article mentions several other companies; Gordon-Van Tine Co., Harris Brothers and Aladdin Co..
So I've started to do some research. Antique Homes has a variety of catalogs on file for kit homes spanning from 1903 to 1961. The Clarke Historical Library has all of the Aladdin Co. catalogs from 1908 - 1954. So far I haven't spotted my little house, but the catalogs are a treasure in themselves! If you like history, architecture, or just sleuthing around on the internet, I really recommend taking a look.
