The DTC Officer’s Mess Annexe is a new two-storey building proposed to be located within the Devil’s Tower Camp area. Its purpose is to serve as an annex to the existing Gibraltar Officer’s Mess and provide additional accommodation rooms for officers. The design includes 10 Junior Officers’ rooms, 10 Senior Officers’ rooms, utility rooms, storage rooms, and a communal/tv room. The contemporary building will have a pitched roof, a stair core on the north side, and a lift for easy access. It will be linked to the existing Mess building to the west.
