We saw this over at Treehugger. A F.L.W. house burned down in Chicago on Monday. The Chicago Tribune wrote: The Wynant House was built about 1915 for the president of a local insurance company. It was believed to be one of the few remaining houses built from Wright's designs by a short-lived Wisconsin prefabricated housing company, American System-Built Houses.
It's wild that, although the house is completely charred, you can still see how stunning it was. A total bummer.
