Description

Oxfam is a group of three-storey buildings with scribed rendered fronts and plinths. They feature a slate roof, red brick chimney stacks, and boarded eaves, along 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, with keystones on the first and ground floors; some windows have been replaced. Nos 9 and 11 have half-glazed doors, while No 10 has a four-panel door with '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, along 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 three-pane modern windows. The largely whitewashed rubble rear of Nos 10 and 11 projects further and features small-pane metal frame casements on No 10, with some glazing bars removed from the ground floor; No 11 has modern casement windows. No 12 has a whitewashed rubble cross range with brick dressings, which is splayed and recessed at the angle, and similar windows to No 10 at the top.

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.
