Anderson Shelters were delivered to families in areas at risk from bombing by the Luftwaffe. They were free for those who earned less than £5 a week and others were charged just £7. All together, about three and a half million shelters were distributed.
The shelters were 1800mm high, 1400mm wide, 2000mm long and intended to sleep up to six people. They came as a 'kit of parts' made from corrugated iron sheets, each about 700m wide. The ' kit' included six curved sheets bolted together at the top plus several straight pieces of various lengths to enable each end to be built leaving an entrance at one end and an escape hatch at the other. People were required to put them together within two weeks of receiving them.
The shelters were half buried in the ground with earth heaped on top for extra protection. They were very cold and damp in winter, so some people put them up inside their houses and covered them with sandbags.
Note: An indoor shelter, the Morrison Shelter, was also made available from 1941. They were in effect a reinforced metal cage about the size of a dining table - and often used for that purpose. They were sited on the ground floor inside a house, and therefore warm, but also very cramped, so larger families preferred the more popular Anderson Shelter.
