Ty Gelli Aur/Golden Grove House, with steps and railings

Ty Gelli Aur, also known as Golden Grove House, is a substantial terraced house dating from the late 20th century. It features painted stucco on its exterior and has a steep slate roof with eaves that are lower than those of the adjacent No 9. The house has a late 20th-century modillion gutter cornice, a red brick stack on the right that adjoins the stack of No 9, and a small stuccoed stack also on the right. The building stands two storeys tall with an attic and cellar, displaying a five-window range and three rooflights. The windows are renewed 12-pane sashes, and there is a central doorway. The cellar has an opening with a 10-pane window set in a raised plinth beneath the left window.

Access to the house is via a flight of five stone steps that rise from the pavement to the doorway, which is flanked by renewed iron railings featuring late 20th-century details. The doorway is adorned with an architrave, a flat hood with a dentil cornice supported by wrought-iron brackets, and an 8-panel door with fielded panels.

The interior has been substantially altered since 1981. Originally, the house featured a vestibule with arches, one of which had a fanlight with tracery, while the other had raised and fielded panelled reveals. The southwest ground floor room was lined with raised and fielded panelling and had a fireplace with bolection moulding on the southeast wall. It also contained fielded-panelled six-panel doors and cornices. The 18th-century staircase had turned balusters, an ornately carved newel, a closed pulvinated string, and a panelled dado above the wall string.

By 2002, most of the original interior features had been removed. The left room retained an elliptical arched recess on the rear wall and a ceiling divided into two panels, but all details had been renewed. The staircase was mostly or entirely renewed, featuring a closed moulded string, turned balusters, and square newels.
