Despite the continued risk of widespread flooding through climate change, living, working, and playing on water continues to be a necessity and a way of life for many. In the context of population increase, rapid urbanisation, and technological advancement, architects and urban planners have an opportunity to rethink the city of tomorrow and embrace an element that accounts for 2/3 of the Earth's surface area. Professor Jason Pomeroy has pushed the boundaries of sustainable design on land through his research into zero-carbon developments and the role of urban greenery in the sky through his pioneering studies into the role of skycourts and skygardens. In this book he explores the ideas behind self-sustaining low/zero energy waterborne communities. Built case studies from around the world and a selection of student's works further explore how to one day address many of the social, spatial, cultural, economic, environmental, and technological challenges of tomorrow.
