Fossil House

Fossil House is a mid to late 19th century house featuring a rear wing (No 33). The building is constructed with rubble stone and has imitation slate roofing for No 39, while No 33 has grouted slates. It is designed in an L-plan and has two storeys.

No 39 has a three-window façade facing Nun Street, with a hipped roof at the southeast angle and a prominent stone stack at the southern end. The southeast corner is accentuated with Caerbwdy quoins. The windows include plate glass sashes on the upper level and large four-pane sashes below, which have been enlarged from their original size. The windows are set on slate sills, and there is a central glazed door. The southern end features a one-window range to the left of the stack, leading into No 33, which continues towards Ebenezer Chapel. No 33 has a three-window range with stone end stacks, brick window heads, two small plate glass sashes, and one larger four-pane sash above, with two four-pane sashes below and a centrally located glazed 20th-century door with a brick head.

In front of No 33 and along the side wall of No 39, there is a dwarf rubble wall topped with slender spearhead railings.
