Description
Broadwater is a house and barn built in one long range, dating from the late 18th century to the early 19th century. It is constructed of flint and brick, topped with a thatched roof. The front, facing southeast, is one storey with an attic and features four windows, with the barn extending to the east side. The roof has half-hips, and the eaves are raised above the upper windows, with a catslide section at the rear. The walls consist of horizontal flint panels, with brick quoins, bands, and cambered arches. The barn walls are boarded, horizontally at the front and vertically at the rear. The windows are casements, and there is a 20th-century porch with a tiled roof.
At the rear, there is an early 19th-century two-storey extension combined with a single-storey outshot, made of red brick in Flemish and Monk bonds, featuring casements and a shallow trellis porch. The two-storey section has a hipped thatch roof with a tiled valley, while the outshot has a slate roof. The barn has a timber frame with five bays and straight angled struts to the Queen post truss.
