Description

Cae Hen is a farmhouse, originally dating to the 17th century and extended in the mid-20th century. The original portion is a two-storey, three-window front, with a two-storey, flat-roofed addition projecting at right angles to the rear, and a single-storey range attached behind that. It is constructed of un-coursed rubble stone, some in large blocks, neatly pointed to the front and buttered to the returns, with a slate roof and rendered integral end stacks. The front features sixteen-pane glazing bar sash windows, all with slate sills and lintels; the first-floor centre window is blind and has a painted "dummy" window, while the lower right window is a replacement with horns. A central entrance has a 20th-century glazed door with a shallow overlight. A sash window is present on the first floor of the left return. The interior was not accessible at the time of survey.

Local climate

Cae Hen sits in one of the wettest parts of the UK, with an average of 1,380 mm of rain a year. This makes it wetter than 97% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 98% of listed buildings.

It experiences an average of 25 freeze-thaw cycles a year, fewer than 73% of listed buildings. Of these, 12 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.
