Description

Semaphore House is a building dating from around 1822, located in Claygate, Elmbridge. It features rendered brick construction on a projecting plinth and has a hipped slate roof. The structure includes a three-storey square tower at the center, a two-storey bay to the left, and a one-storey bay to the right, all built over basements. The windows throughout are 20th-century glazing bar sash windows. To the left of the tower, there is a projecting single-storey porch with a window, and a panelled door on the left side of the porch, which is accessed by a flight of six steps. At the time of the last survey, the house was undergoing restoration. Semaphore House is part of a series of semaphore towers that extend from Portsmouth to Whitehall, as noted in Pevsner's "Buildings of England, Surrey."

Semaphore House sits in a drier-than-average part of the UK, with an average of 720 mm of rain a year. This makes it drier than 83% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 78% of listed buildings.

It experiences an average of 32 freeze-thaw cycles a year, fewer than 59% of listed buildings. Of these, 14 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.
