During the late 1930s as the second world war looked increasingly likely the Royal Air Force expanded massively. Lots of airfields were built all across the East Coast of England especially in Lincolnshire and Norfolk. These bases were not built to the same quality and standards of the large pre-war bases such as RAF Waddington. Instead these bases were made of initially grass runways and multiple dispersed accommodation and technical sites constructed using prefab and simple standard buildings. In addition, to the temporary buildings Hotels and stately homes were often commandeered and used for things such as an Officers Mess.

Today the hall is now the home to about 10 small companies
