A circular structure measuring some 7.9m is shown on aerial photographs dating to May 1946 as thin white circle enclosing a dark area. The structure is within the garden of bungalow. The circle of concrete remains visible on modern aerial photographs re-used as a gaden feature. Two other such features are visible on the same aerial photographs (see NPRNs 506515 and 506743).
