Abstract: Shenzhen’s urban renewal has a history of more than ten years since 2009, and over 95% of its renewal projects mainly adopt the mode of demolition and reconstruction. As cities enter the stage of high-quality development, the original renewal model has become unsustainable, and urban organic renewal emerges as the times require. Taking Unit 01 of Bantian North Area, Shenzhen City, Guangdong Province as an example, this paper explores the technical methods and implementation system for the organic renewal of urban villages in highdensity built-up areas. It has formed a new transformation model for original rural communities in highly urbanized areas, namely ’partial demolition and reconstruction+partial comprehensive renovation’, explored a new path for the implementation of stock planning and the application of the ’urban renewal+land preparation’ policy toolbox, and solved the planning and implementation problems in high-density built-up areas. Additionally, a quantitative analysis model for stock planning benefit distribution and planning scheme adjustment is established to ensure the feasibility of the planning scheme and the optimization of spatial form. This paper also innovates the design method covering node selection, retrofit evaluation, and node space design, thereby realizing the creative transformation of fragmented space in urban villages within high-density built-up areas.
