Population increases, advances in technology and the continued trend towards inner-city migration have transformed the traditional city of spaces into the modern city of objects. This has necessitated alternative spatial and technological solutions to replenish those environments that were once so intrinsic to society’s day-to-day interactions and communal activities. This book considers skycourts and skygardens as ‘alternative social spaces’ that form part of a broader multi-level urban infrastructure – seeking to make good the loss of open space within the built environment. Jason Pomeroy begins the discussion with the decline of the public realm, and how the semi-public realm has been incorporated into a spatial hierarchy that supports the primary figurative spaces on the ground or, in their absence, creates them in the sky. He then considers skycourts and skygardens in terms of the social, cultural, economic, environmental, technological and spatial benefits that they provide to the urban habitat. Pomeroy concludes by advocating a new hybrid that can harness the social characteristics of the public domain, but be placed within buildings as an alternative communal space for the 21st century. Using graphics and full colour images throughout, the author explores 40 current and forthcoming skycourt and skygarden projects from around the world, including the Shard (London), Marina Bay Sands (Singapore), the Shanghai Tower (China) and the Lotte Tower (South Korea).
