Bastion House

Bastion House is a house, later converted to offices, dating to around 1820, with alterations in the late 19th century. The building is constructed of brick with ashlar detailing, a slate roof, and brick stacks topped with chimney pots. It consists of a three-storey main block and a slightly later, three-storey cross wing projecting to the front left, with a single-storey entrance porch built into the re-entrant angle. A single-storey, late 19th-century bow window in ashlar has been added to the front of the wing.

The front of the main block has boxed eaves supported on brackets, while the front wing has a parapet. The ground-floor entrance doorway to the porch features brick jambs and a semicircular stone arch with a raised keystone and a fanlight with radiating glazing bars. To the right of the porch are two sashes with 3x4 panes. The first floor has a narrow sash with 2x4 panes above the porch, and two similar sashes to the right. The second floor has three shorter sashes with 3x2 panes above the porch and 3x3 panes to the right. The late 19th-century bow window on the front wing features a moulded cornice with a frieze band and blocking course, and three curved plate-glass sashes in openings with moulded stone jambs, flat arched heads, and sloping sills. The front wing’s first and second floors have two sashes with 3x4 panes on the first floor and 3x3 panes on the second floor. The north return side of the wing has sashes with 2x4 panes on the ground and first floors, and 3x3 panes on the second floor. All original sashes are set within openings with five raised, stepped voussoirs forming flat arched heads and have projecting stone sills. A mid-19th century block to the rear features a full-height canted bay with glazing bar sashes and rusticated quoins. The interior has not been inspected. The house is located on the site of a bastion which formed part of the defences constructed between 1644 and 1651 to protect the City of Gloucester during the Civil War siege by Royalist Forces.
