Shed Number 78, Sheerness Dockyard

The building was constructed at the Royal Navy Dockyard in Sheerness in 1856–60, as a store for small boats and a warehouse.

The building was constructed for the Admiralty Works Department by Colonel Godfrey Thomas Green CB of the Royal Engineers (1807-1886) (formerly from the Bengal Sappers and Miners, and later Director of Admiralty Works), and William Scamp (1801-1872), with ironwork cast by Henry Grissell's Regent's Canal Ironworks.

It is an unusually large example of a boat store, built using an innovative structural system, with an all-metal frame incorporating metal portal bracing.

Its listing entry with Historic England states that it is "of international significance in the development of modern architecture".

A frame of cast-iron H-section columns and I-section joists divides the side aisles into 7 bays along their length.
