The Charged Void: Urbanism is the companion volume to The Charged Void: Architecture; the two together comprise the complete works of Alison and Peter Smithson. For the designers, architecture and urbanism were inseparable: buildings encapsulate urban ideas; urban systems are the means by which buildings function effectively. This second book collects both urban and architectural designs that have specific implications for city form into fourteen thematic chapters: the Team X Doorn Manifesto with its worked examples (Close Houses, Fold Houses, Terraced Crescent Houses); large-scale designs such as the Berlin Hauptstadt, Hamburg Steilshoop, and the Kuwait Urban Form Study; and built manifestations of urban ideas, notably the Economist Building of 1959-64. More than a collection of work, The Charged Void: Urbanism represents a record of a focused thought process concerned with the qualities of urban life—a thoughtful and witty collection of observations, decipherings, and recommendations for understanding and improving the complex nature of the city.
