Description

Granville House is a house that has been divided into two dwellings. It dates from the early 19th century and may have been modified from an earlier structure, with later 19th-century additions to the rear. The building is constructed of red brick, featuring a chequerwork pattern in flared headers on the main elevation, while the rear is made of yellow brick. It has hipped slate roofs.

The principal block is three storeys high and one room deep, with rear blocks that are two storeys high and include attics. On the east elevation, there are two sets of sash windows, one set of windows, and two more sash windows per floor, although the spacing is slightly uneven. All windows have stucco surrounds with moulded keyboards, and the first and second-floor windows still have their glazing bars. The first floor features a central French window with marginal lights that opens onto a balcony with cast iron railings, which is formed by the top of the porch.

The porch has square piers with bands of diamond rustication that support a moulded cornice. The doorway, accessed by a flight of steps, has a bracketed open pediment and contains a French window along with a semi-circular fanlight that has ornamental glazing bars. There are stucco bands at the first and second-floor levels and a moulded eaves cornice.

On the south elevation, the fenestration includes a Venetian window with glazing bars on the first floor, along with other sash windows that are set under gauged brick heads. The porch features a leaded canopy hood on panelled timber piers that shelters a partially glazed door, and there is a moulded brick dentil cornice above the first-floor windows.

Local climate

Granville House 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 96% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 83% of listed buildings.

It experiences an average of 33 freeze-thaw cycles a year, fewer than 53% 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.
