Elevating the public realm: a framework for designing resilient urban green spaces in hyperdense cities

This study examines the critical role of elevated urban spaces in fostering urban resilience and enhancing public well-being in the post-pandemic era. Through a detailed literature review and contextual analysis, the research explores how these spaces address the evolving needs for social interaction, public health, and mental wellness in urban design. Focusing on London, with comparisons to international examples such as Singapore, the study presents findings from sixty-six semi-structured walk-along interviews conducted at the Sky Garden and Crossrail Place Roof Garden. Data analysis reveals both the challenges and guiding principles for designing resilient elevated urban spaces. Key areas for improvement include accessibility, circulation, aesthetic integration, and management strategies. The findings emphasise the value of these green spaces in densely populated cities, as they provide vital recreational areas that support the mental and physical health of residents. This research offers a structured framework for embedding elevated green spaces into high-density urban environments, enhancing both resilience and liveability. The study delivers actionable insights for urban planners and policymakers, outlining a nuanced approach to designing sustainable, adaptable green spaces.
