Urban masterplans remain an exploratory ground for unbuilt speculation, offering insight into how cities might recalibrate mobility, ecology, and collective life in response to accelerating environmental and social pressures. In this Unbuilt edition, submitted by the ArchDaily community, the selected projects bring together a range of large-scale proposals that examine urban centers, waterfront districts, infrastructural corridors, and cultural landscapes as spatial frameworks for reconnection and resilience. Rather than treating the masterplan as a rigid blueprint, these projects approach urbanism as an adaptive system shaped by climate, topography, infrastructure, and public space.
Across varied geographies, from Northern European town centers and Mediterranean coastal districts to Central Asian polycentric hubs and Gulf megacities, the proposals explore diverse architectural and urban strategies. They range from park-led civic transformations built over highway tunnels to elevated pedestrian networks above active transport systems, mixed-use blocks structured by historic planning logics, marina developments integrating environmental stewardship, and research-driven models for equitable landscape urbanization.
