Summaried from report:

Barrack Hut 3a is the most northerly barrack block, is terraced into the terreplein. Its different form and plain neo-Georgian detailing set it apart from the 1890 buildings, though it provides similar accommodation on a broadly similar plan. Drawings dated August 1928, and subsequently maintained as record plans, indicate that it was intended for 30 men and one NCO. Construction began in October 1928, with completion the following September. Fenestrated as ten bays, the building has brickwork in English garden wall bond and a renewed slate roof carried by timber king-post trusses. With the exception of the sanitary annexe, the interior was broadly the same as in the earlier huts. Two large barrack rooms, accommodating fifteen men each, flanked the entrance, NCOs room and Ablution Room, but the passage, instead of being L-shaped, was T-shaped to provide access to the annexe as well.
