Description

The Grange is a large two-storey house built in the 18th century, with alterations and additions made by Sir Charles Nicholson in the early 20th century. The house is constructed of red brick and features a tiled roof. It has six windows across the front and includes projecting wings, with sash windows that have glazing bars. There is an off-centre porch and a modillion eaves cornice. The garden front showcases a two-storey bow, which is considered the most notable external feature of the house. Although it has undergone many changes, it remains a structure of significance.

Local climate

The Grange sits in one of the driest parts of the UK, with an average of 690 mm of rain a year. This makes it drier than 98% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 98% of listed buildings.

It experiences an average of 30 freeze-thaw cycles a year, fewer than 66% of listed buildings. Of these, 13 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.
