Description

Thanet House is an early 19th-century house located set back from Twickenham Road in Isleworth. The building is constructed of yellow brick and features a central three-storey projection with two-storey wings on either side. It has two double-hung sash windows, with glazing bars present only in the centre of the first floor, which is framed by architraves and cambered relieving arches. The first floor also has modern casement windows. The house is topped with a dentil cornice, a parapet, and a hipped roof covered in Welsh slate. There is a modern brick porch at the entrance, along with modern gates and a wall surrounding the property.

Local climate

Thanet House sits in one of the driest parts of the UK, with an average of 700 mm of rain a year. This makes it drier than 92% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 90% of listed buildings.

It experiences an average of 30 freeze-thaw cycles a year, fewer than 64% 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.
