Architect Butler calls the home’s design flower-like, with the stem being the foyer (pictured) and main stairwell. The three petals consist of a master bedroom, a living-dining area and two guest rooms that double as offices. The design allows for the four different zones to be individually regulated by a central smart-house automation system, further minimizing energy consumption. Bench: homeowner’s own; Rug: “Dhoku Rug,” Wynne Alex, SF; Glass vase: Pottery Barn.
