Located next to a lake in Chenequa, Wisconsin (west of Milwaukee), this curvaceous residence was beautifully built by architect Robert Harvey Oshatz . Designed in 2009 and completed in 2011, the Chenequa Residence wraps around the face of a hill and pivots around established trees. The internal spaces extend out from a central atrium which is anchored by a circular stone core that almost looks like a tree trunk from afar. The clients wanted a building, constructed from natural materials, which acted as one with its environment and provided unobstructed views and connections to the surrounding landscape. I don’t know what the house is valued at, but I’m guessing it’s more than a few hundred Putt-Putt tickets.
