Description

Oxfam is a group of three-storey buildings with scribed rendered fronts and plinths. The buildings have slate roofs, red brick chimney stacks, and boarded eaves, with cill bands on the first and second floors. Nos 9 and 10 are a reflected pair with one window each, while Nos 11 and 12 have two windows each. The windows at Nos 9 and 12 are nine-pane sash windows, mostly horned, featuring keystones on the first and ground floors, although some have been replaced. Nos 9 and 11 have half-glazed doors, while No 10 has a four-panel door with an 'imported' architrave.

No 11 has a shop front with a two-light window, a panelled stallriser, and a half-splayed entrance. No 12 features a full-width shop front with a central double door entrance flanked by segmental-headed panes, with a single pane to the left and twin panes to the right, also with a panelled stallriser.

In the center of the building, between Nos 10 and 11, there is a round-arched entry leading to a tunnel passage with boarded doors, a brick wall to the left, and rubble to the right. The rear of No 9 is rendered and has modern three-pane windows. The largely whitewashed rubble rear of Nos 10 and 11 projects further, with small-pane metal frame casements on No 10 (some glazing bars removed on the ground floor) and modern casement windows on No 11. No 12 has a whitewashed rubble cross range with brick dressings, splayed and recessed at the angle, and similar windows to No 10 at the top.

Local climate

Oxfam sits in one of the wettest parts of the UK, with an average of 1,180 mm of rain a year. This makes it wetter than 90% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 82% of listed buildings.

It experiences an average of 53 freeze-thaw cycles a year, more than 94% of listed buildings. Of these, 32 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.
