Description

Longbourne is an early 18th century house that has two storeys and a basement, featuring five windows. There is a two-storey extension on the left with four windows. The front, which dates from around 1800, is stuccoed and includes end pilasters, an entablature, and a parapet. The centre bay of the house projects slightly. It has sash windows with glazing bars set in exposed frames. Access to the house is via four steps leading to a 19th century half-glazed door located in a pedimented Ionic porch.

It experiences an average of 32 freeze-thaw cycles a year, fewer than 58% 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.
