Hartnells Sergeants Mess Former Bodmin Depot

Hartnell's Sergeants' Mess, formerly the Bodmin depot, is a disused sergeants' mess built in 1881. It was designed by Major H.C. Seddon of the Royal Engineers at the War Office. The building features squared rubble with stone dressings, stone gable and ridge stacks, and a slate roof, arranged in an L-shaped double-depth plan.

The exterior consists of two storeys and a basement, with a five-window range. The main east front has a central projecting gable that includes a round-arched tympanum with plate tracery. The north side displays a pair of coped gables with moulded kneelers set forward, paired lights, a plain entrance to the parapetted central section, and a two-light section to the right. Additional features include cill bands, an eaves cornice, plain surrounds, and 4/4-pane sash windows.

Inside, there is a staircase with an iron balustrade. This building is a unique example of a standard design for Localisation Depots, which were part of the Cardwell reforms aimed at redistributing barracks across the country to foster local connections and enhance recruitment. It is one of the two most complete surviving depots and is notable for being constructed of stone, as well as being attached to the former Militia armoury.
