A traditional 19th century Pennsylvania barn was the nucleus of this rehab and addition project resulting in a residence for a Chester County, Pennsylvania family. The original barn was renovated and converted to provide personal spaces, and a barn-inspired timber frame structure added on at right angles to the barn. The addition has a view of the pond, and houses all the common spaces of the home – living and dining rooms, kitchen, and even a large area with a swing hanging from the rafters. Atypically, the walls of the addition are almost all glass, brightening the interior – with its uniformly dark surfaces – immeasurably. On the exterior photo, note the hot tub sunk to floor level on the exterior deck. The addition timbers are rough-sawn oak.
