The modern use of the term "Dutch Colonial" is to indicate a broad gambrel roof with flaring eaves that extend over the long sides, resembling a barn in construction. The early houses were often a single room, with additions added to either end (or short side) and very often a porch along both long sides. Typically, walls were made of "jersey" sandstone and a chimney was located on one or both ends. Common were double-hung sash windows with outward swinging wood shutters and a central double Dutch door.
