[1] As new sites for development were sought out, so the Kemp Town Brewery Co. purchased a 5,000-acre estate near the rural community of Lullingstone in Kent.

[3] In August 1936, it was reported in the Kentish Times that the Southern Railway were proposing to establish an aerodrome at Lullingstone which would be used by Imperial Airways.

[4][5] The airport would be served by a new station on the Maidstone East Line, electrified between Swanley and Sevenoaks in 1935,[6] which would be situated 19 miles 39 chains (31.4 km) from London Victoria.

[7][5] Although the proposal was abandoned by the Southern Railway,[8] it was taken up by the Air Ministry which saw Lullingstone as the most suitable site for a fourth airport to serve the London metropolis.

[11][18][19] The introduction of the post-war Green Belt Act put a halt to any potential residential development and the incomplete station, standing in the middle of fields, was useless.
