Description
Cemlyn is a two-storey building constructed from roughly coursed and shaped boulder rubble, laid in large blocks. It features a modern slate roof with red tiled cresting and end wall stacks. The front elevation has a wide gable that dominates the facade, with a central entrance that has a flat stone lintel above the doorway. This entrance is flanked by 16-pane sash windows, which align with small 9-pane windows on the first floor. Above the doorway, there is a round-headed window at the center of the gable.
Local climate
Cemlyn sits in one of the wettest parts of the UK, with an average of 1,550 mm of rain a year. This makes it wetter than 99% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 99% of listed buildings.
It experiences an average of 20 freeze-thaw cycles a year, fewer than 79% of listed buildings. Of these, 8 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.
Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
