Description

The Round House is a detached house built in the early 19th century, with mid-19th century additions to the south. It is constructed of Flemish bond brick and features Westmorland or Welsh slate roofs and brick stacks. The house is octagonal in shape with rectangular additions, standing two stories high with a basement and a five-window front. The entrance is a 20th-century door located in a hipped-roofed porch on the octagon, and all windows are 20th-century metal casements set in Tudor-arched openings, retaining some Gothic glazing bars at the tops. There is a two-brick plat band and a dentilled eaves course.

At the rear, there are 20th-century French windows leading to the basement, framed by a gauged brick Tudor-arched opening. A 20th-century addition to the left matches the style of the rest of the house, while some earlier brickwork in header bond at the base of the rear wall suggests that an earlier octagon may have existed on the same site, possibly dating back to the early 18th century. The right side of the house features a 20th-century porch. The interior was undergoing extensive alterations at the time of survey in December 1984, conducted by Longford Estate. The house is situated in a picturesque location on a bank overlooking the River Avon and was likely originally visible from Longford Castle, possibly built as a landscape feature.
