No House is Just a House: House Interviews, Space-Use Intensity, and City-Making

Abstract

This article argues that to understand housing as domestic only is a misconception. People intensify the use of their homes in ways that create substantial economic opportunities, urban services, and a range of social protections for themselves and their communities. The research presented here introduces the concept of 'space-use intensity', in fluenced by time-use surveys, Jane Jacobs's ideas on mixed-use, and the continuum approach to the informal economy, as conceptualized by Elinor Ostrom. Further, it describes the 'house interview' methodology devised to document spaceuse intensity and presents findings from houses in informal se lements in Bogotá, Kampala, Dar es Salaam, and Dakar. The data reveal that houses are less than a third residential (29 per cent), almost half of the uses are economic (47 per cent), and they provide a fair share of urban or community services (24 per cent). This visual methodology demonstrates that local governments are overlooking 83.8 per cent of the activities taking place within homes. In sum, the evidence discussed here shows that homes contribute signi ficantly to the urban economy and public services, making space-use intensity analysis instrumental in the design of eff ective housing, urban, and social protection policies.
