Discussion on the Comprehensive Utilization and Improvement Design Mechanism of High Plot Ratio Stock Land Resources

Urban Farm DB summary

Set against the backdrop of accelerating urban stock renewal in China, this paper addresses the contradiction between "quantity" and "quality" in developing high plot ratio land—where rigid plot ratio constraints create physical barriers such as insufficient lighting, chaotic circulation, and lack of public space, while demand for quality living raises requirements for spatial openness, ecology, and social inclusiveness. It analyzes design strategies including composite utilization of underground space, ecological compensation through rooftop gardens, and cross-plot three-dimensional corridors, combined with coordination of ownership division, full-process cost control, and policy tool innovation, to construct a comprehensive improvement mechanism of "physical optimization, ownership coordination, and economic balance," intended to provide a replicable design paradigm and decision-making reference for improving the quality and efficiency of existing land in high-density urban development.
