Description

Mount Hill is a late Georgian villa that has a roughly square plan and a U-shaped roofline with a central valley. The walls are rendered, and the roof is covered with slate. There are two brick stacks on the left-hand ridge and a stack with paired round shafts on the right-hand ridge, which were overgrown at the time of inspection.

The front of the villa has four bays with pointed windows featuring small-pane sashes and Gothic glazing bars. The entrance is located to the left of the center and is accessed through an added open gabled porch supported by posts. The door has blind Gothic panels and is topped by a pointed overlight with Y-tracery.

On the right side wall, there are three pointed sash windows similar to those on the front, along with a square-headed fixed small-pane window further to the right. The rear elevation features a two-storey left-hand gable end that incorporates service rooms, while the right-hand gable is set back.

The property was not inspected during the assessment.

Local climate

Mount Hill sits in one of the wettest parts of the UK, with an average of 1,320 mm of rain a year. This makes it wetter than 95% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 96% of listed buildings.

It experiences an average of 21 freeze-thaw cycles a year, fewer than 78% of listed buildings. Of these, 8 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.
