Description

Bay House School, formerly Ashburton House, was built in 1832 by Decimus Burton. It is one of the large mansions associated with Alverstoke. The southeast front features a complex three-storey block with a long east wing that ends in a pavilion. The building is designed in a Gothic Revival style that has some Baronial elements, including gablets and hood moulds above the windows. The walls are made of stone ashlar, and there are moulded eaves, bands, and a plinth. The building also has Tudor chimneys and retains some original interiors.

Bay House School receives an average of 800 mm of rain a year. This makes it drier than 54% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 74% of listed buildings.

It experiences an average of 20 freeze-thaw cycles a year, fewer than 79% 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.
