Description

Cortlandt is a 18th century house located at No 18 George Street in Hailsham, formerly known as No 20. It was once the offices of Hailsham Rural District Council and is named after Major Van Cortlandt, an American Royalist officer who settled in the area after the War of Independence. The building has two storeys and an attic, constructed with grey headers and a tiled roof.

The original part of the house features three windows topped with a modillion cornice and a pediment that contains a Venetian window illuminating the attic. The ground and first floors have three bays, with red brick quoins and tile-hung sections between the windows. The central bay on the ground floor includes a doorway flanked by sidelights, a rectangular fanlight, and a six-panel door. The end sections of the building have large, four-sided bays with six windows, which were added in the late 19th century.
