Description

Corllan is a single-storey and loft building, featuring whitewashed roughcast walls and a roof made of corrugated iron over thatch. It has a large roughcast stack on the right end, which includes a date plaque, and a small brick stack on the left end. The front elevation has a ledged door with an overlight, flanked by 4-pane horned sash windows on each side. To the right, there is a small square fire-window. The windows have stucco surrounds and slate sills. There is a 20th-century addition to the right of the building.

Local climate

Corllan sits in one of the wettest parts of the UK, with an average of 1,170 mm of rain a year. This makes it wetter than 90% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 95% of listed buildings.

It experiences an average of 13 freeze-thaw cycles a year, fewer than 88% of listed buildings. Of these, 6 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.
