"The owners wanted nothing in the master bedroom," Bertram says. The architect was happy to oblige, building a glass skybox with a 10-foot-4 ceiling, exposed structural supports and a simple cork floor. From the entry, what appears to be a wooden half wall turns out to be the back of a headboard with attached nightstands. Outside, the flat roof of the living room forms a 150-square-foot terrace. Flooded with light, the room can be darkened and cooled with the aid of motorized recessed Sivoia shades by Lutron .
