Description

The main building of Cottesmore School, located in Lower Beeding on Busham Hill, is a large mansion built in the Elizabethan style between 1882 and 1883 for P. Saithard, an ostrich-feather merchant. The school relocated here from Hove around 1955. Designed by architects Eshart George and Harold Peto, the building features a half-H plan and is constructed of vivid red bricks. It stands three storeys tall and has twelve windows, with a Horsham slab roof and tall brick chimney stacks. The windows are casement style, and the wings have shaped gables. The central portion of the building includes a six-storey tower topped with a balustrade and a turret that is corbelled out from the top three storeys at the north-east corner. There is also a porte cochere to the north-east of the tower, which has a balustrade above it.
