Description

Prospect House is an early 19th-century, three-storey, three-window house. It features colourwashed plaster on a rubble base and has a moderately pitched slate roof that is hipped towards Rhosmaen Street, with plain eaves and rendered stacks.

The second floor has six-pane sash windows and a band running along it. The first floor has twelve-pane sash windows, also with a band, while the ground floor features canted bay windows topped with dentil cornices. The windows are Victorian sashes with narrow side sashes. The central doorway has a depressed arched doorhead, with a lattice-glazed fanlight above a panelled door.

The front elevation curves around to Rhosmaen Street, where there is a one-window elevation with a six-pane sash on the second floor and twelve-pane sashes on the first and ground floors.

To the right on New Road, there is a shopfront that adjoins the house. This shopfront has a moulded cornice over a plain fascia, with gabled fascia ends supported on fluted brackets and panelled pilasters. The recessed doorway at the right end has a floral pierced fanlight above a half-glazed door, and there are pierced rosette toplights above the plate glass shop window, which features a tiled stallriser.

Prospect House sits in one of the wettest parts of the UK, with an average of 1,400 mm of rain a year. This makes it wetter than 97% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 94% of listed buildings.

It experiences an average of 39 freeze-thaw cycles a year, more than 74% of listed buildings. Of these, 18 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.

Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
