Junkspace first appeared in the Harvard Design School Guide to Shopping (2001), a vast compendium of text, images, and data concerning the consumerist transformation of city and suburb from the first department store to the latest mega mall. The architect Rem Koolhaas itemized in delirious detail how our cities are being overwhelmed. His celebrated jeremiad is updated here and twinned with Running Room, a fresh response from the cultural critic Hal Foster. Junkspace describes the bleak and featureless world of capitalism, while Running Room seeks to find a space within the junk in which the individual might still exist.
