Pen-y-grisiau

This is a red brick townhouse, built in the 18th century, with a slate roof and brick end stacks topped with decorative, dentilled cornices from the 19th century. The house has two storeys and a basement, originally three bays wide. The ground level features a rendered plinth and flat eaves. The windows are large, 24-pane sash windows with curved tops, set within curved brick surrounds. The ground-floor windows have been replaced in the late 20th century; the window on the left is a replica, while the right one was found in the basement. A central flight of four stone steps, reducing in size upwards leads to a tall doorway with a flush-panelled six-panel door, architrave frame, and a fanlight with radiating bars and an open pediment hood supported by console brackets. A basement opening with louvres is located on the left-hand side. A rebuilt section of red brick forms the south end wall. The rear, east side of the house has a small dormer window and an attached, two-storey rubble stone wing with a low-pitched roof. The south wall of this wing features a six-panel door and a three-light window with top lights. A later, narrower wing, parallel to the north side of the main house was added in the 19th century.

Inside, the central hall contains a straight staircase. The lower treads are modern, while the rest of the staircase dates to the mid-18th century and features turned balusters in the form of a short column. Similar balusters are found on the first-floor landing. The upper staircase and attic landing have turned newel posts and flat shaped balusters, reminiscent of the late 17th century, although they are likely from the 18th century. A ground-floor room on the southwest side of the house has a six-panel door, a covered axial beam, and a modern fireplace. The northwest front room contains two covered beams and a chimneypiece made of pink and grey veined marble with decorative circular elements (paterae), which was moved from an upstairs room. A rear cloakroom, on the north side, has a cross-window with an iron opening light. A 19th-century wing was added to the rear, northeast side of the house. A further wing, likely added in the late 18th century, is located on the rear, northwest side, and includes a high-ceilinged kitchen and a bedroom above. The kitchen features a plank door and two brick-headed fireplaces on the east wall; one is a broad, cambered arch supported on iron straps, while the other is narrower and round-arched. The first-floor rooms on the south side are narrow and have plank doors, revealing evidence of cut-back chimney breasts. The attic lacks roof trusses but contains very long, heavy purlins, similar to those found in the Old Stores House on Arthur Street. A loft window is situated at the north end. A cellar is located beneath the northwest room, constructed from rubble stone lined with walls with curved corners.
