Density has long been an essential consideration for architects and urban planners, yet its importance has only increased as the world’s urban population skyrockets and cities become denser and denser. For much of the history of urban planning, this term has been plagued with negative associations: overcrowding, poverty, lack of safety, and so-called ‘slums.’ The garden city movement, initiated by Ebenezer Howard in 1898, sought to remedy these ills by advocating for greenbelts and anti-density planning. Le Corbusier’s Radiant City is one of the most well-known urban plans building from these ideals. Yet in the 1960’s, sociologist Jane Jacobs famously overturned these long influential urban planning concepts: she pointed out that density of buildings was not identical to overcrowding of people; suggested that some highly dense urban areas, like her neighborhood in Greenwich Village, were safer and more attractive than nearby garden city projects; and highlighted how America’s conception of ‘slums’ were often rooted in anti-immigrant and anti-Black ideologies. Density is not inherently bad, she suggested, but it has to be done well. Today, we continue to grapple with the question of how to design for our increasingly dense cities – how do we keep them open, but simultaneously private? Free, but controlled when necessary? In particular, how do we keep them safe – both from crime and, in the age of COVID-19, disease?

Denise Scott Brown once said: “Architecture can’t force people to connect; it can only plan the crossing points, remove barriers, and make the meeting places useful and attractive.” Although it cannot control the outcome, architecture holds the potential to set the stage for chance encounters and social interactions, thus nurturing community building and influencing the fabric of our social culture. The following explores how architecture can improve the social capital of its surroundings through design strategies and thoughtful programming, creating the fertile ground for social interaction among different groups of people.

The challenges associated with the provision of adequate and affordable housing around the world demand that architects respond with original solutions that challenge traditional building forms, typologies and methods of delivery.

PLANE–SITE brought together the architects of four inventive housing projects. These projects represent a diversity of approaches to similar housing challenges across radically different global contexts. From the redensification of European urban centers to the rapid urbanization of the tropical Asian megacity, these radical housing models challenged existing paradigms in order to advance resident well-being as their principle design concern. In contrast to Schumacher’s divisive speech, the panel illustrated projects that were deliberately designed to promote community life and social interaction between residents – and in some cases also with other citizens in spaces that blur the line between public and private.
