Water interacts with light in different ways: absorbing, refl ecting, refracting and bending it. This book explores different water conditions through the lens of architecture to reveal the interrelationship between the natural phenomena and our spatial experience. Set in a Danish context, there is a particular intimacy with water that is deeply embedded in the collective identity - water is perceived as something familiar, a fundamental life source and continuous source of inspiration. Water is understood not only as a physical element but also as a cultural and emotional condition, infl uencing how space, light and materiality are experienced.
