Building 69 (Breaking-Up House), Rnad Bull Point

This is a single-story store, likely built around 1856-1858. Constructed of limestone ashlar with rock-faced quoins, plinth, and dressings, it has a slate roof. The building has a rectangular plan.

The exterior has a two-window range. The gables at each end feature segmental-arched windows on either side, a blocked oculus above, and a central wooden lean-to section. The northeast side has three flat-headed windows in the centre, with doorways on either side and pairs of smaller, segmental-arched windows at the ends. The northwest side features outer segmental-arched doorways with boarded doors and two windows in the middle. The windows have metal glazing bars from the 20th century.

The interior exhibits timber trusses and matchboarding at the south end. Brackets remain for steam heating pipes.

The building was possibly originally a Breaking-Up House, used for dismantling defective ammunition. By the 20th century, it served for examining and packing small stores. It is one of several key buildings constructed around a road extending from the magazine enclosure at Bull Point.

Bull Point, established as the last major project of the Board of Ordnance before its abolition in 1856, provided storage for 40,000 barrels of gunpowder. The site integrated a floating magazine for unloading powder and the 1805 St Budeaux laboratory, where it was checked and processed, before being moved to the Bull Point magazines. The complex was uniquely dedicated to processing and storing new types of ordnance, influencing naval ship and fortification design. The buildings, styled to match the magazines, are mostly in ashlar with rock-faced dressings, fronting an avenue south of the magazines. They represent the finest ensemble within any Ordnance Yard and a remarkable example of integrated factory planning from the period, consistent with the high standards practiced by the Ordnance Board in designing fortifications and barracks from the 17th century onwards.
