High On...Light + Architecture explores the role and use of light in and around modern buildings. This full colour book illustrates how a greater understanding of this intangible and free material leads to better architecture and improves our quality of life. It explains why light is so fundamental to human perception, how its nature and use are influenced by time and place and how it has come to be used as a tool for abstract architectural design. Drawing on centuries of thinking and over 30 international examples, the author explores the different ways that light can be harnessed and manipulated to achieve particular objectives, emotions or experiences, as well as how the technologies and techniques for doing so have developed over time.
