IN-PERSON Lisbon Livable Cities. Section A

Abstract

This essay explores the relationship between housing models and social interaction, highlighting how architectural design and spatial organisation influence neighbourhood dynamics. It examines the concept of graded privacy, which transitions from public to private and intimate spaces, and highlights its role in fostering meaningful interactions and building community ties. Key themes include the integration of residential buildings into their urban environment, the connection between buildings and streets, and the importance of transitional and communal spaces within buildings to encourage social engagement among residents. Collaborative housing models such as co-housing and co-living are analysed to understand how their spatial configurations can enhance social ties and community identity. The essay assesses how these housing models balance private and communal needs while creating inclusive environments that encourage interaction at different levels – from casual encounters to deeper connections. It also highlights the value of shared and semi-public spaces as central elements in fostering a sense of belonging and mutual support within residential developments. Methodologically, the essay draws on a theoretical review and on the analysis of architectural projects to identify scalable and adaptable solutions for urban housing that respond to contemporary challenges. By prioritising human-scale design and emphasising the integration of residential and communal spaces, it offers insights into innovative housing strategies capable of strengthening neighbourhood identities and enhancing social resilience. This contribution enriches urban studies by addressing the complex interplay between architecture, urban planning and the social dimensions of housing in modern cities.
