Description

Folly House is a picturesque "Gothic" folly built in 1849 on an island within the River Thames. The building is constructed of red and grey brick, incorporating battlements, wrought iron balconies, and Coade stone statues set within niches. It stands three and four storeys high, featuring sash windows with glazing bars and French windows. Extensive decorative brickwork is a prominent feature. The roof is not visible from the street.

Folly House sits in a drier-than-average part of the UK, with an average of 730 mm of rain a year. This makes it drier than 78% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 69% of listed buildings.

It experiences an average of 32 freeze-thaw cycles a year, fewer than 59% of listed buildings. Of these, 14 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.
