Fort Pitt Grammar School for Girls (Domestic Science Block)

The Domestic Science Block of Fort Pitt Grammar School for Girls is an early 19th-century building originally constructed as a barrack block for Fort Pitt, part of a system of Napoleonic forts designed to protect the Medway towns. It later served as a lunatic asylum. The building is made of gault brick in English bond, with a rendered rear and a hipped roof covered in Welsh slate. It stands two storeys tall and features two large ridge stacks. A coped parapet, dentil cornice, and a first-floor sill band extend around the entire structure.

The front (north) elevation has a five-window range, with the five first-floor and two ground-floor windows featuring 24-pane sashes set in reveals beneath flat brick arches. There is a later central porch. A gabled single-storey projection is located to the northwest. The rear of the building is symmetrical with a five-window range, where the windows match those at the front, except for the larger central ground-floor window, which has late 20th-century glazing bars. The sides have horned sashes and smaller inserted windows. Inside, there is a dog-leg staircase.
