Description

The Cwm is an early to mid 19th century cottage built from colourwashed rendered rubble stone, topped with a grouted slate roof and featuring stone stacks. The cottage is two storeys high and double-fronted, with two 19th century plate glass sash windows on each floor, the upper windows being smaller. Each window has slate sills, and there is a central doorway with a 20th century door. To the north, there is a lean-to addition, while a flat-roofed addition is located to the south. A painted rubble garden wall surrounds the property.

It experiences an average of 3 freeze-thaw cycles a year, fewer than 99% of listed buildings. Of these, 1 follows 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.
