Taliesin East by Frank Lloyd Wright
Commemorating Frank Lloyd Wright's entry into UNESCO heritage sites, here's a build of Taliesin III (aka Taliesin East), the architect's own home studio in Wisconsin. Actually just the front side of the sprawling complex, like the official LEGO Imperial Hotel set. Considering that the LEGO Architecture series has been quite engaged in doing FLW buildings, this could be a nice addition.
Unlike other works by FLW, Taliesin kept evolving over time; sometimes for living/working space expansion, or to showcase his newest architectural ideas to his clients, or due to repeated tragedies involving fires. Accordingly, the house looks like a messy assemblage of modules, but still somehow retains beautiful integration.
