Description
Holwell Manor is a house dating from the early to mid-18th century, with alterations and enlargements made in the late 19th century. It features chequered brickwork and a machine tile roof, standing two storeys high with attics and five windows. The entrance elevation has segmental-headed single windows on either side of a modern Tuscan porch, along with five flat-headed first-floor windows. The windows are flush 19th-century sashes with gauged brick lintels. The garden elevation includes a central door set in a moulded frame, with a two-light fan and a small hood supported by leaf-scrolled brackets, as well as similar windows. There are three triangular-headed casement dormers and a two-storey extension.
