Former Royal Naval Hospital The Square Numbers 11, 12 And 12A And Attached Walls

The Former Royal Naval Hospital, located at The Square, includes Nos. 11, 12, and 12A, along with attached walls. This officer's house was built around 1765 and designed by Alexander Rovehead for the Navy Board. It features Plymouth limestone rubble with limestone quoins, architraves, and a band above the ground floor and first-floor string in the central bays. The building has dry slate roofs across three levels, with hipped ends, except for the taller central block which has a mansard roof, large stone end stacks, and two gabled dormers. The central block is topped with a pediment that has a spoked lunette and a parapet in front of the flanking roofs.

The exterior consists of two storeys plus an attic, with a pedimented central block flanked by two-storey blocks and single-storey blocks at each end, creating a symmetrical façade with a 1:3:3:3:1 window arrangement. Most openings feature original or 19th-century hornless sash windows with glazing bars. The central block has a Venetian window on the first floor, with a spoked centre light and blind sidelights, and a later enclosed rendered porch beneath it with a central window and side entrance. The flanking blocks have central wooden porches with fielded panels, moulded cornices, glazed doors, and sides, along with overlights containing small panes.

The interior has not been inspected but is known to have retained original features. The property is also accompanied by high rubble front garden walls with ramped coping, as well as part of the original perimeter wall of the hospital, which was designed to prevent patients from escaping. Historically, these houses were shown in 1800 as the residences of the steward's clerk and the agent's clerk, and they are part of a significant and complete military hospital complex.
