Description

Knapp House is a detached house with origins dating back to the 17th century, although it was extensively altered in the early 19th century. It is constructed of ham stone ashlar and features a hipped Welsh slate roof behind a high parapet, along with stone chimney stacks. The building has two storeys and consists of six bays, with the first two bays set lower and likely built separately.

The exterior includes a plinth, cornice, and plain parapet, with sash windows in plain openings. The upper windows in bays one and two have 16 panes, while those in bays three, four, and five have 20 panes. The lower windows in bays one and two are small-pane casements, while bays three and four feature large 20-pane sashes. Bay six is set higher and has a bow front, with matching windows below and plain sashes above, arranged in pairs on the curve. The lower bay five has an elliptical arch with a pair of part-glazed doors, which are sheltered by an open stone porch supported by early pattern Doric columns and pilasters, topped with a plain entablature and flat roof.

The south front mirrors the two-bay design, although the upper windows are blind. The house was referred to as Naphouse by 1778. In 1934, it became a Roman Catholic Mass Centre until a new church was built in 1961. Following this, it was converted into St Elizabeth's House for Elderly Ladies.
