Description

No 20 is a cottage from probably the late 18th century, constructed of painted stone rubble. It is two storeys high and features two windows with two-light casements that have horizontal glazing bars. There is a central doorway, and the cottage has a slate roof with gable ends. It also has end chimney stacks and lean-tos. This building is included for its group value, as it contributes to the overall character of the village group in Polkerris.

Local climate

20 sits in a wetter-than-average part of the UK, with an average of 990 mm of rain a year. This makes it wetter than 80% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 87% of listed buildings.

It experiences an average of 10 freeze-thaw cycles a year, fewer than 91% of listed buildings. Of these, 4 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.2°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.
