Description

The Watch House is a small, single-storey building that has the character of a traditional cottage. It is constructed from whitened rubble and features a shallow, hipped slate roof. A tall, round lateral chimney with a conical cap is present. The seaward end, which faces southeast, is supported by tapering octagonal columns, creating a loggia. The building has small-pane glazing, with French windows in the center and small, asymmetrically-placed windows with small-pane glazing along the long side elevations.

Local climate

Watch House sits in one of the wettest parts of the UK, with an average of 1,490 mm of rain a year. This makes it wetter than 98% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 97% of listed buildings.

It experiences an average of 32 freeze-thaw cycles a year, fewer than 60% of listed buildings. Of these, 15 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.
