What is the human scale? An ancient question without a definitive answer in philosophy, but also very concrete in architecture. Human scales, urban scale, or the lack of scale in some buildings are among its core issues. It is all the more surprising that thorough investigations into architectural scale are rare. Silke Vosskötter explores what lies behind the promising concept of scale, which has shaped the design and evaluation of buildings for centuries. In her book, the numerous aspects encompassed by the concept of scale are explained and methodically organized. Based on architectural theory and psychological knowledge, the effects of building sizes and configurations are demonstrated through numerous examples. With this knowledge, sensitivity to the formation of context-specific appropriate scales can be sharpened.
