Compact urban form has been widely suggested as a more sustainable development pattern that enhances different aspects of social liveability such as social exchange, collective interaction, and outdoor activity. Empirical research, however, challenges proposing a generic and universal understanding of compactness and its social advantages: compactness is perceived and lived differently in different socio-cultural contexts. This paper contributes to the call for gaining a more place-specific understanding from the compact urban form. To do so, it examines the social life of compact neighbourhoods in two study sites in Berlin. Social life is investigated by measuring the two dimensions of “neighbouring” and “social activities”: while the former explores how residents of the neighbourhood perceive different aspects of social life, the latter maps how urban space accommodates different types of social activity. Questionnaires and advanced mapping techniques are the primary sources of research obtained through intensive fieldwork and on-site observation. The research findings challenge some dominant assumptions attributed to the compact urban form orthodoxy: a compact neighbourhood can be perceived as safe, offer acceptable home and neighbourhood satisfaction, and, at the same time, suffer from low social networking and community engagement.
