Light and air playfully permeate every level of this house, from the slatted “tree house” floating above the living room, to wrap-around clerestories and a second-story glass bridge. To preserve usable outdoor space—a precious commodity on this small urban lot—architect Glen Irani developed a two-story bar that hugs the lot’s long edge. A perpendicular second-story arm shelters an outdoor living terrace at the entryway, giving the major rooms garden access and eliminating the gratuitous front yard.

Four bedrooms upstairs are tucked under a stainless-steel-clad roof, which folds down over high glazing for privacy from taller neighbors. “There’s always some light creeping around the edges of the roof,” Irani says. “The roof doesn’t sit hard on the building, but feels like a soft blanket protecting your head from the elements.”

Natural materials underscore the landscape connection. The house is clad in deeply tinted cement plaster, and the refined al fresco living room has a bleached walnut ceiling, basalt stone fireplace, and French limestone flooring. The judges admired the terrace and its placement, also noting that the house’s details are “executed very well, and nothing seems overdone.”
