This chapter draws on studies of urban marketplaces in South Korea to discuss the approaches to space taken by vendors. The iterative design of market carts employs a range of strategies geared towards the optimum display of goods and establishing the vendor-buyer relationship. Other instances demonstrate how tightly constrained contexts encourage innovative spatial strategies and how the human body is transformed into a surface by porters. This presents an alternative narrative for architecture and the making of space, presenting the market as a temporally sophisticated model of architecture.
