Former Weedon Barracks, Storehouse Number 5

The Former Weedon Barracks, Storehouse Number 5 is a Grade II* listed warehouse built between 1804 and 1810. It is part of an unusual group of buildings located to the north of the canal. In 1844-1845, it was converted into the Governor's Quarters for the military prison, although most of the later additions were removed by 1899. The building is constructed of Flemish bond red brick with gauged brick dressings around the arches. It has a hipped corrugated asbestos roof that replaced the original M-shaped Welsh roof, and mid-19th century brick stacks were added for prison staff.

The storehouse has a rectangular plan with a central vestibule and stairs leading to flanking storerooms. It stands two storeys high and features an 11-window range on the south elevation facing the canal. The central entrance has 12-panel double-leaf doors flanked by stone pilasters that support a Doric entablature, with cambered arches above tripartite sash windows. There are similar wider blocked doorways at either end, with corresponding windows above, and the panelled double-leaf doors are still present on the right (east) gable end. The ground-floor windows are semi-circular arched, consisting of two-light wooden casements from the late 19th century, set within semi-circular arched recesses. The first floor has late 19th century horned 6/6-pane sashes. The centre and ends of the building project slightly, and there is a plinth and a first-floor string course.

To the left (west) gable end, there is a mid-19th century addition that is two storeys high and has a single bay with similar sash windows, built to accommodate stairs for prison personnel. This addition features a blocked doorway at the front and a further mid-20th century addition at the front.

Inside, the first floor is supported by three rows of chamfered timber posts with pillow beams. Steel trusses were added in 1938 when the roofs were remodeled. The open string staircase has chamfered and scroll-stopped newels, diamond-set balusters, and a moulded handrail. Semi-circular arched doorways, set in semi-circular arched recesses, provide access to the storerooms.

This building is part of a unique planned military-industrial complex, which includes its own defensible transport system and surrounding walls. For more details, refer to the description of Storehouse Number 2.
