London is a city of innovation. In its suburbs, green roofs grow on flats, homes are insulated with cork and light timber structures have been designed to be as beautiful as they are energy efficient; in the center, striking new offices are retro-fitted over preserved buildings, while communal hubs are creatively built from reclaimed materials. The original photographs and detailed design interrogations in this book look at the way the capital is responding to the ever-pressing need to build with the environment foremost in mind – talking to the London architects, designers and residents who are creating a city that lives, works, plays and produces sustainably.
