The small house movement is a return to houses of less than 1,000 square feet (93 m 2). Frequently the distinction is made between small (between 400 square feet (37 m 2) and 1,000 square feet (93 m 2)), and tiny houses (less than 400 square feet (37 m 2)), with some as small as 80 square feet (7.4 m 2).
