Description

Deseret is a double-fronted house that stands one and a half storeys high. It is pebble-dashed over stone and features a slate roof with a stack on the right side. The windows have been replaced and include raked half dormers, all set within smooth-rendered surrounds. The central entrance is marked by a lean-to porch that has a half-glazed door. To the left side, there is a two-window extension that also has a slate roof, a stack at the left end, and a doorway in the gable end. The rear of this extension is splayed, as the house backs onto the road. Additionally, the rear of the main house has an added half dormer.

Local climate

Deseret 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.
