The house is attractively wrapped in glass, rain-screen siding and black-bar grating, which is employed in the guard rails and the brise soleil (the sun-shading baffle running above the main level’s glass walls). Given the building site's closeness to the street, instead of a yard, layered elements—steps, concrete walls, planters—were used to create separation and privacy. (As with the hedge on its opposite corner, an existing Japanese maple provides privacy and natural beauty.)
The tip-off to the existence of a rooftop deck is a discreet section of guard railing. The pop-up section is the apex of the broad skylight, which not only pours daylight into the middle of the house, but, thanks to a code exception, allowed Cobb to push up the height limit a bit so, instead of an awkward hatch, a normal-size door leads out onto the deck.
