The base of the structure is board-formed concrete, while the cantilevered wings are made of steel and glass.
The outdoors is welcomed in at nearly every turn, with expansive windows and wide-swinging doors that celebrate the interior/exterior connection. A 23-foot-wide pivot door on the steel and glass bridge allows the entire south-facing wall to open, transforming a simple connection between the two wings (main house and guest quarters) into functional space. In the lower level sewing room, ?eroding corner? glass doors swing open to an intimate courtyard. The master bath features an indoor/outdoor stone shower with Montana moss rock. The cantilevering wings are supported by structural concrete masts that serve double duty as fireplaces.
