Porth Angel, including rear garden wall to Picton Place

Porth Angel is an end-terrace house built in an L-plan, featuring painted roughcast and a slate roof that is hipped at the left. The house has paired bracketed eaves and a brick stack on the right. It is two stories tall with a three-window range, showcasing later 19th-century detailing. The upper floor has late 19th-century tripartite plate glass sash windows on either side and a single plate glass sash window in the center. The ground floor features canted stuccoed bay windows with hipped roofs on either side of a central arched doorway. This doorway has a late 19th-century stucco surround with a cambered head and chamfered and stopped piers. There are three stone steps leading up to a 20th-century glazed door with a plain fanlight. A thin stucco sill course runs along the first floor, and there is a plaque on the party wall that is partially obscured, possibly dated 1829.

The elevation facing Picton Place is stucco lined to resemble ashlar, with a north gable end. It has a two-window range set to the left, featuring 12-pane sashes on the first floor, a 20th-century door, and an 8-pane sash window below. To the left, there is an addition with garage doors and a small window above. A rubble stone garden wall extends along Picton Place for about 25 meters.

The house has undergone many alterations, and its unusual plan indicates that the front hall is skewed towards the rear range, suggesting that the rear range may be older, although a map from 1834 shows only the front range. There is a short section of the original stair balustrade leading down to the cellar, which features a bulbous newel and open treads. The staircase is located on the rear wall at right angles. The front rooms have reeded ceiling borders, and some doors have been covered over. The house includes a large cellar and two six-panel doors on the first floor front, with three more in the rear wing.
