This simple 1,400 square foot lake house under a sloping, standing seam metal roof that reflects sunlight is designed with a specific reference to the traditional Texas, “dog trot house,” to minimize heating and cooling requirements. On one side is the private space: a master bedroom; and, bath. Separated by the “dog trot” on the other side, is the public space: an open kitchen, living; and, dining room, which can be divided by movable walls to create separate sleeping areas for guests. Screened doors on the entire exterior south wall of the house open during warm summer months to capture cool breezes. During winter months, they are covered by large sliding barn doors to keep the cold air out. A raised timber deck surrounds the house and projects into the landscape.
