A group of four rectilinear structures or huts set in a square seen on 1945 RAF aerial photographs situated immediately to the north of Perry's Farm. These range in size from 3.5m x 12m to 3.5m x 20m) Immediately to the north-east are five dispersed small structures (between 1m and 2m across) which may be part of the same complex. It is not clear if these are agricultural or military structures, but they are not seen on later photographs of the area. They were mapped from aerial photographs as part of the English Heritage: Hoo Peninsula Landscape Project.
