A relatively simple, economical wall construction once used in the United States for small houses and dependencies; has an exterior appearance similar to that of board-and-batten construction. The walls are constructed of
closely-spaced, wide, upright boards, approximately 1 inch (2.5 cm) thick; the cracks between the boards are covered with vertical battens only on the exterior surface of the boards. The sillplates are secured on a foundation consisting of flat stones.
