Over more than five decades, legendary architect Moshe Safdie has built some of the world's most influential and memorable structures - from the 1967 modular housing scheme in Montreal known as Habitat to the Marina Bay Sands development in Singapore. For Safdie, the way a space functions is fundamental; he is deeply committed to architecture as a social force for good, believing that any challenge, including extreme population density and environmental distress, can be addressed with solutions that enhance community and uplift the human spirit. If Walls Could Speak takes readers behind the veil of an essential yet mysterious profession to explain through Safdie's own experiences how an architect thinks and works - from the spark of imagination through the design process, the model-making, the politics, the engineering, the materials. Relating memorable stories about what has inspired him - from childhoods in Israel and Montreal to the projects and personalities worldwide that have captured his imagination - Safdie reveals the complex interplay that underpins every project and his vision for the role architecture can and should play in society at large. Illustrated throughout with drawings, sketches, photographs, and documents from his firm's voluminous archives, If Walls Could Speak is a book like no other, and will forever change the way you look at and appreciate any built structure.
