Description

This is a decorative shelter made of painted corrugated iron, designed to resemble a tented pavilion. It features fictive swags and has a central raised ball and star finial, along with flanking fleurs-de-lis, all of which are two-dimensional and cut-out in form. Inside, there is a slatted bench that is used during the summer months.

Local climate

Corrugated Iron Shelter 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.
