Description

Sunnyside is a house that dates from the 17th century or earlier, with later recasing in the late 18th century or early 19th century. There is a mid-19th century extension on the left side. The building features a timber frame with red brick walling, and the left bay is constructed in rat trap bond. It has one storey and attics, with three replacement glazing bar casements and two box dormers from the 18th or 19th century. At the rear, there is a slightly taller central projection that includes a 17th-century lateral red brick chimney stack on the right side. The left gable end displays thin exposed framing.

Local climate

Sunnyside sits in a drier-than-average part of the UK, with an average of 720 mm of rain a year. This makes it drier than 82% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 79% of listed buildings.

It experiences an average of 32 freeze-thaw cycles a year, fewer than 57% 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.
