This book features the design, creation and use of air raid shelters, including interviews with people who used them during the Second World War. The different types of bunkers/air raid shelters (both public and in people's gardens) are covered and the strength and weakness of their designs discussed, using original designs and primary material. The nostalgia/social history of the book covers people's experiences of staying in the air raid shelters. These are divided into topics, including getting to the shelters (how they reacted to the sirens or whether they just moved into the shelters, especially those in gardens, long-term), facilities, health issues, morale and safety, both real and perceived.
In recent years, air raid shelters have been converted into different uses, including homes, and the book will finish with a brief chapter concerning the future and preservation of these once vital buildings.
