Ty Nanney, including forecourt walls, gate piers and gate

Ty Nanney is a late Georgian house dating from the late 18th century, featuring a symmetrical design of a three-bay main block flanked by lower, one-bay wings on either side. The main structure is built from roughly dressed blocks of quarried stone laid in regular courses, topped with a hipped slate roof extending from deep bracketed eaves. Stone stacks with double V-shaped ends rise from the roof. Openings are accentuated by simple hoodmoulds. A metal open trelliswork porch, with a swept pyramidal roof, now covers the central entrance, which leads to a door featuring two round-headed panels. The lower-storey windows are 16-pane horned sashes, while those on the upper storey have 9 panes. The wings each have a 12-pane hornless sash on the lower storey; the upper storey of the wings features blind windows with painted glazing bars. A garden wall is attached to the left (south) end.

Further details include French doors and a 12-pane sash window on the lower storey of the left (south) end wall; above this is another 12-pane sash window. A rear, single-storey lean-to has been added to the south wing, featuring a glazed door to the left and paired 16-pane sash windows to the right. A small-pane window is on the left side of the upper storey of that wing. A lower, two-storey gabled rear wing has an end stack and features a 24-pane sash on the lower storey of its south side, alongside a similar 16-pane window under a gable in the upper storey and a smaller inserted window to the right. The opposite, north wall has a former 16-pane sash window where the lower sash is missing and boarded over. To the left of the rear wing is a lower, two-storey lean-to against the main building, incorporating a half-glazed panel door and small-pane windows replacing former openings in both storeys. Further to the left is a single-storey, half-hipped lean-to against the north wing, with a 12-pane sash window. The north end wall features a 12-pane hornless sash window in the upper storey, and boarded-up lower-storey and right-side windows, the latter converted from a doorway.

Coped forecourt walls run from the front of the house down to the street. The front is punctuated by low, central gate piers with a wooden fretwork gate. Taller, square gate piers, set apart by a vertical joint indicating a later date, provide vehicular access on the right side.

The house’s interior is centrally planned, with a full-height, open-well staircase featuring plain balusters and newel posts. The central stair hall and the kitchen in the rear wing are floored with slate flagstones. The kitchen’s fireplace has a large slate-stone lintel.
