To make the interior feel more spacious, the architects opened the ceilings to create a double height space. They clad everything above eight feet, the original ceiling height, in plywood to maintain a human scale and the house’s original proportions. The sofa is from Hay, the Tokyo chaise lounge is from a now-closed Bellport vintage shop, the coffee tables are by Giotto Stoppino, produced by Kartell 1950s and 1960s, and the yellow chair, inspired by Pierre Paulin, was a find at Wright Auctions. Lisa painted the artwork on the mantel. Photo 4 of 13 in Budget Breakdown: She Turned a Long Island Cottage Into a Creative Retreat for $418K
