The Old Storehouse

Limestone rubble with granite dressings, hipped slate roof. Basement and two storeys, 9 bays divided 3-3-3, the centre 3 slightly advanced and pedimented, rendered parapet elsewhere. Granite plinth, quoins, surrounds to ground floor arched recesses and first-floor windows, impost band, plain two-step cornice, and coping to pediment and parapets. Cast-iron small-paned windows, with radiating bars to ground floor. Tilting lower opening half to each window.

Lower windows are set in recessed arches with limestone ashlar infill. Full width double doors in painted iron with radiating bar fanlights to centre of N, E and W elevations. Upper windows are 20-pane with plain surrounds, but N side centre has loading door with iron hoist adjacent. Basement area to N and S. Six cellar doors each side.

Storehouse is constructionally similar to the much larger storehouses at the other Royal Dockyards, but smaller because Pembroke was not used for final fitting out or victualling.

Extensive fireproof construction with stone axial wall, and stairs, iron doors through, two rows of columns carrying big cast-iron beams with fish-bellied cast-iron joists, on which York stone flagstones were laid. Upper floor not inspected but said to have iron roof construction.
