This work investigates the rapid erosion of London's architectural heritage and the urgent need for preservation in the face of post-war urban development. Candida Lycett Green and Christopher Booker utilize their expertise in architectural history and journalism to document buildings under threat of demolition. The text serves as both a historical record and a call to action, analyzing the socio-political forces that prioritize modernization over the conservation of historic structures.

The text provides a focused, polemical examination of urban conservation, reflecting the specific anxieties regarding London's architectural identity during the early 1970s. Its documentation remains a valuable resource for understanding the historical context of the city's preservation movement.
