I've written about Gunnison Homes before in this blog. See: http://cresourcesinc.blogspot.com/2010/07/former-gunnison-factory-new-albany.html. Running across a newspaper article while I was doing research gives me an excuse to post up a bit more information.
From his factory, which still stands in New Albany, Indiana, Foster Gunnison produced pre-fab homes built with insulated plywood panels in an assembly-line system. Forbes called him the "Henry Ford of housing." Raw materials arrived at the front door, the walls, ceiling and floors were factory finished, doors hung and "windows installed, washed and screened" as the panels moved along the conveyor belts and out the rear door onto trucks headed all across the nation.
Indianapolis builder, Robert L. Mason was the local rep for the Miracle Homes. It's hard to know how many of these little Miracles were built in the city, but the demonstration home shown in the picture at the bottom of the article and located in the 3500 block of North Keystone Avenue, still stands as you can see in this google maps pic. I wonder if its owners know the history of their house?
