The Presbytery of the Roman Catholic Church of St Mary

The Presbytery of the Roman Catholic Church of St Mary is a pair of houses constructed in 1829. The building is constructed of knapped flint with gault brick dressings, and has pitched roofs covered in Welsh slate. The original domestic plan of each house remains legible, though the plan has been adapted to create a single interconnected building.

The building is two storeys high with a pitched roof and gables facing northeast and southwest towards the church. It features a dentilated eaves cornice and two gault brick ridge stacks.

The northwest elevation, which faces Newtown, is three bays wide, with six-over-six timber sash windows on both floors. The ground floor centre has an oak double-door with an arched fanlight, all within rusticated brick surrounds. The northeast elevation is gabled and has arched openings with rusticated surrounds. A six-panel door with a glazed fanlight is centrally located on the ground floor, flanked by windows. There are two sash windows at first floor, and a single window at attic level. The ground floor windows are rectangular, with the arches above them blocked-in. The southeast elevation has a more informal appearance, using a mixture of flints and field stones laid as random rubble. The ground floor and first floor have a variety of timber-framed windows within red brick surrounds. A small porch is located on the right-hand side, and there are numerous scars and bricked-in features suggesting earlier openings or extensions.

Internally, the houses retain their original plans, including separate staircases and entrance halls. Notable features include surviving chimney breasts and fireplaces, original joinery such as doors and window frames, and staircases with open strings, stick balusters, mahogany handrails, and curtail steps with monkey tail newels. The attic of one end house has an exposed roof structure of common rafter construction with rough-hewn structural members, a crude balustrade around the central stairway, wide pine floorboards and lath and plaster walls.
