Built between 1938 and 1939, RAF West Raynham was an expansion scheme airfield. The grass landing area was aligned roughly north-east to south-west. The main camp, with housing and headquarters, was located immediately west of the landing area. To the south-east were bomb stores. The airfield was originally equipped with a Watch Office with Tower (Fort Type), of pattern 207/36 (made from concrete), although the original control room was later removed and new larger control room built to pattern 4698/43. The newer VHB type control tower was a post war addition.
