This was one of three Wright houses in the Usonian neighborhood. For more information see the Sol Friedman Residence and the Edward Serlin Residence. The road was very confusing and the map provided in The Frank Lloyd Wright Companion did not seem right. I thought it might be the mirror image since the roads seemed backwards.
Unfortunately, I was not able to find the third Wright house, but I did take some pictures of the other Usonian houses and grouped them on the Edward Serlin Residence page.
