Yes, I've read up on this before and it's really interesting. We had many local architects/builders here at the time of the Sears catalog homes so I'm not sure if we have any. I'll ask our exec director of our historic foundation.
We found lumber in this house with the name of the original owner on it, which is how it came from the lumber yard. We also found true 4x4s in the wall that were slightly rough hewn, which was really interesting.
What I found most interesting from the photos in your link was the mission style 2-story home. Our house which is c. 1908 originally had a mission style double porch front facade made of stucco. When the house was moved, that was pulled off because of its poor condition and the front porch with upper pavilion was built more in the traditional "accepted" style of other surrounding homes. The mission facade was in contrast to the more elaborate ionic columns in the front formal rooms of this house. It was a more unique home in its original facade, I think.
How about those prices for those Sears homes?
