Barrack Block (Building 57), Jellalabad Barracks

The Barrack Block (Building 57) at Jellalabad Barracks in Tidworth is a building dating from around 1905. It is constructed of brick with rubbed brick dressings, featuring brick ridge stacks and a slate roof. The building has a single-depth plan and includes two attached front towers that house non-commissioned officer (NCO) rooms and stores.

The exterior is two storeys high and has a symmetrical arrangement with a total of 28 windows, divided into four sections. Each section features a central double doorway with a boarded door and segmental-arched paired 2/2-pane sashes, each with an overlight. A full-length cast-iron verandah spans two storeys and includes first-floor railings with diagonal bars. The two sections on either side have two-storey square storage towers, which are connected by bridges to the first floor above external dogleg stairs. Each floor of the towers has two rear 6/6-pane sashes. The rear of the building includes two ablution blocks.

The interior has not been inspected but is noted to have entrances that lead to through passages connecting the barrack rooms.

Historically, Tidworth was established after the purchase of Salisbury Plain for large-scale military training manoeuvres. This barrack block is one of four identical double company blocks, each containing six 12-man rooms arranged symmetrically, and it forms part of a battalion unit within Tidworth Barracks. It is recognized as an example of an important type of standardized barracks design.
