The site for this house slopes directly toward the water. Traditionally, one enters a house on the first more public floor with bedroom and private spaces located up a flight of stairs. Here, one enters on the second floor, and descends a flight of stairs to the more private floor. As this site is on a lake, the horizon plays a significant role. This project considers the horizon as a mirror. If we cut an architectural section through the site, a curving line is discovered. If this line is inverted about the horizon, another curve is reflected. This house finds its form in such moves. The horizon is the line along which we measure the length of a day. The house faces due south to maximize use of the sun throughout. At night, one enters the lower western side of the house and settles down alongside the sun.
