When designing a lake house, it is best to connect with nature—not compete with it. "In everything we did, we tried to enhance the beautiful surroundings and keep all eyes on the view," says Atlanta designer Yvonne McFadden, who worked on this house with architect Keith Summerour. Comfort and practicality were also key. "The clients wanted space to host at least 12 of their friends and family," she says. Their design combines an airy, open floor plan (including a wall of windows that faces the water) with a rich mix of natural materials for a space that marries function and style.
