A major phase of housing expansion took place after World War I, increasing by three times to World War II. Half of this growth, 94 houses, was due to the "Severn Tunnel Garden Village Society", constituted in 1924, whose membership was limited to railwaymen. Population increased from 136 in 1921 to 234 in the 1931 census. Many railwaymen still commuted from the other local villages though, and over a thousand worked at Severn Tunnel Junction by the outbreak of World War II.
