This book highlights the alternatives envisaged by international experts about how we will live within a few decades: inevitable high-rise cities due to urban crowding or eco-friendly and self-sufficient metropolises are some of the prevailing trends seen in the seventy-plus projects included in the book. Via photos, plans, architectural illustrations, sketches, diagrams, texts and captions, this volume offers readers a clear image of the types of housing and cities to expect in a possible, and not so distant, future.
