For Christopher Day, architecture isn’t just about the appearance of buildings but how they’re experienced as places to be in. Occupants’ experience can differ radically from designers’ intentions as their concerns and thinking differ. Additionally, multi-sensory ambience, spatial sequential experience and embodied spirit resonate in the human soul. Sustainable design means much more than energy-efficiency: if sustainable buildings don’t also nourish the soul, occupant-building interaction will lack care and eco-technologies won’t be used efficiently. This major revision of his classic text builds on more than forty years of experience ecological design across a range of climates, cultures and budgets, and 25 years hands-on building. Treating buildings as environments intrinsic to their surroundings, the book explores consensus design, economic and social sustainability, and how a listening approach can grow architectural ideas organically from the interacting, sometimes conflicting, requirements of place, people and situation. This third edition, comprehensively revised to incorporate new knowledge and address new issues, continues Day’s departure from orthodox contemporary architecture, offering eye-opening insights and practical design applications.
