New Cooperage, Royal William Victualling Yard

The New Cooperage at the Royal William Victualling Yard is a cooperage building constructed in 1899 for the Victualling Board. It is designed in the Georgian Revival style and is made of granite ashlar with a granite ridge and a hipped, tiled roof.

The building has a rectangular single-depth plan and is a single storey high, featuring a symmetrical front and rear elevation with four windows. The end sections of the building are set forward and include a plinth, a banded ground floor leading to a plat band, a flat cornice, and a parapet. The ground floor windows are segmental-arched, while the first-floor windows are flat-headed with plain surrounds. The first-floor windows on the north end consist of 6/6-pane sashes. The southeast elevation has banded surrounds for the loading bays at both the ground and first floors, which are equipped with double boarded doors located three bays from the ends of the central section. The northwest end has a middle bay that is set forward, featuring banded pilaster strips and a segmental-arched doorway with a double six-panel door, while the southeast end has loading doors on both floors. There are stacks located two bays from the ends; the northwest fireplace stack is wide with a cornice, and the southeast features a tall, square furnace stack. The roof includes four wide flat-headed four-light dormers below the ridge, which were formerly used as vents.

Inside, the building has rolled steel trusses and is divided by cross walls. The north end contains a stone stair, while the south end has the base of the furnace stack. Historically, the New Cooperage included a carpenters' shop, a seasoning room, a central coopers' shop and store, and first-floor offices at the north end. The coopers were moved from the Old Cooperage by the Naval Ordnance Department in 1891. The external design of the New Cooperage reflects the style of earlier buildings at the Royal William site, and it is recognized for its architectural quality and group value with the rest of the Yard, which is a unique planned industrial enterprise.
