Description

Roundwell House is a semi-detached house dating from the 17th century, with modifications made in the 20th century. It is constructed from cut and squared ham stone with ashlar dressings and features a triple-roll clay tiled roof between coped gables. The house has brick and stone chimney stacks, one of which has a traditional baffle.

The building is two storeys high and has four bays. The upper bays two and three and the lower bay four have hollow-chamfered mullioned windows set in wave-mould recesses with labels, although the mullions have been removed from the upper bay two. The upper windows are partly set into the coped gables. Bays one and four feature 20th-century gabled dormers with steel casement windows. The lower bays one and two have two-light horizontal bar casements of 19th-century design, while lower bay three has a pair of 20th-century French doors set in a flat-arched beaded ashlar surround. To the right of bay four is a two-light plain mullioned window with a label. Between bays two and three, there is a six-flush-panel door set into a panelled recess with a label above. The east gable has further mullioned windows, with three and two lights above, the larger one having a label, and below it, there is a three-light window without a label. The interior has not been seen.
