Description

7-8 Upper Colliers Row is a pair of joined, mostly altered, two-storey stone cottages with slate roofs, located within a row of similar structures. Some original stone chimneys remain, and a few window openings have not been enlarged. The cottages feature catslide roofs at the rear, many of which have been extended. Several cottages have been combined, and there are gardens in front with some remaining stone walls. To the south, there is an area of irregular enclosures or allotments associated with the cottage row.

Nos 7 and 8 are covered in painted render and have stone end stacks that are shared with Nos 6 and 9. Each cottage has a four-pane casement window above, positioned relatively close to the center. No 7 features a broad 20th-century triple casement window to the left and a ledged door. There is another casement window above the door, which is likely an insertion. No 8 has a window in a former doorway to the left and a four-pane casement window to the right, which is set further out than the window above. In 1975, there were plate-glass sash windows present.

The interior has not been inspected, but it is reported to have joisted floors, fireplaces on the left and right, with winding staircases nearby. No 7 features timber elements, while No 8 has stone elements.
