Description

5-6 Upper Colliers Row is a pair of joined, mostly altered 2-storey stone cottages with slate roofs. 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 5 and 6, now referred to as No 6, have late 20th-century render and share stone chimneys with Nos 4 and 7. The doorways are set within a double late 20th-century porch, and the window openings have been renewed with brick sills, with the ground floor openings widened and the upper ones positioned relatively close to the center. The rear has been extended to form a gable and is tiled.

Inside, the cottages have joisted floors, and the ground floor is now one room. There is a fireplace to the right with a winding stone staircase adjacent, while the fireplace to the left has been removed, and the original timber staircase has been replaced by a 20th-century timber staircase. There is a room and kitchen to the rear in the 20th-century extension.
