Located on a steeply sloping site in Louisville, Tennessee, this small house for a single person is organized around its relationship to the Tennessee River. One enters the house through a covered vestibule with splayed walls that focus views towards the water.  Glass doors parallel to the entry draw the eye through the foyer to the observation deck overlooking the river. The kitchen, living and dining space share the same volume, but are defined by floor levels and a study loft above the kitchen. These spaces are visually connected to the water by a large window wall on the east facade. During the spring and summer months, the sun reflects off the water and filters through the trees, washing the space with a dappled, flickering light.  Small, punched openings on the west elevation provide a degree of privacy from the adjacent road and allow late afternoon light to penetrate across the space.
