Two Harry Bertoia-designed chairs sit on the main third story deck, which includes a hidden green roof that absorbs rainwater, cools the upper floors, and purifies the air. “It’s a nice little oasis on the roof, with plants that bloom at different times of year. The owners love spending time up there,” Dubbeldam says. Photo 6 of 8 in Contrast House by Laura C. Mallonee
