"We call it the design the '2 Bar House' because there's a horizontal and perpendicular bar; one of the bars really looks over the other's roof. It would be unfortunate to only look out over this shiny white roof," says Feldman. "The master suite could be this thing that was kind of unfortunate, or it could be this secret garden and so the green roof became this splurge. A green roof is never something we design when we're out of money because it costs much more than a standard roof."
