On the chapter covering Air Raids: "Your Home as an air raid shelter" (Issued by the Ministry of Home Security, 1940) offers practical suggestions:
"There are three ways in which you can provide your household with shelter. First, you can buy a ready-made shelter to bury or erect in the garden. Secondly, you can have a shelter of brick and concrete built into or attached to the house. Thirdly, you can improve the natural protection given by your house by forming a "refuge room." The first two of these generally give better protection against bomb splinters than the third but cost more."
