Though many of Amy Lau’s clients live in or just outside the city, the Manhattan-based designer has designed several, often second homes for clients in the Hamptons. So when one of her clients tasked her with installing an upscale beach aesthetic in his Bridgehampton manse, Lau’s mind was already spinning with ideas. But it wasn’t until she saw the large, unobstructed views from the 1,700-square-foot home, which sits adjacent to the Bridgehampton Polo Club, that she knew where to draw inspiration. “When you’re looking out these great windows, you’re seeing so much color—like the citron of the flowers outside the windows. So we really wanted to bring the outside in,” says Lau of the dining room’s color palette.
