Former Oakum Store

The Former Oakum Store, built in 1856, now serves as Royal Navy offices. It is constructed from grey squared limestone and features a slate roof behind parapets. The building is two stories tall and has a T-shaped plan, with a rectangular ground floor. The west range has pediments on both the north and south sides, while the east spine range is pedimented to the east, displaying datestones from 1856. The east range includes slate-roofed lean-tos on either side that are flush with the end walls of the west range, and it has stone coping on the east side.

The structure features an ashlar plinth and band, which extends around as an eaves band on the lean-tos, along with a plain two-step cornice that wraps around the entire building. The ground floor has arched openings linked by an impost band. The upper windows are casements with top lights and ashlar voussoirs. The south front has a pedimented three-window section to the left, with a blocked broad arched door in the center. There is a slight recess to the right, featuring a ground floor arched doorway with a 20th-century door, and the first floor has a possibly later addition with one matching window and a parapet. To the right, there is a two-bay lean-to with a broad arched doorway, which has been converted into a window with a radiating bar fanlight, along with a window to the right. The two windows above the lean-to are shorter than those found elsewhere.

The north front is similar but the lean-to extends to the pedimented block and has a window-door-window-door arrangement, while the pedimented block features a door-window-window configuration, with doors matching the width of the windows. There are three windows above the lean-to, similar to those on the south side.

The east end has a three-bay center with a broader first-floor center window, and arched windows below that resemble those on the lean-to ends, with a blank doorway to the left. The west wall is five bays wide with a blank center door and no center window, although the third window consists of a pair, breaking the symmetry.

The window glazing is likely not original.
