Against the dual background of ICH (intangible cultural heritage) revitalization and urban stock space renewal, the renovation of traditional craft workshops has shifted from limited workshop repair to comprehensive space creation that balances craft protection, cultural dissemination, and sustainable operation. While existing scholarship has explored the functional composition and qualitative design strategies of ICH workshops, there remains a notable research gap in quantitative spatial performance evaluation frameworks tailored to craft production constraints, and the actual contribution of spatial design to living heritage transmission lacks objective measurement tools. This study takes craftsmanship-oriented ICH workshops as the core research object. Based on field investigations, multi-subject questionnaires, and expert consultations, 14 tertiary indicators are selected from three dimensions: production and safeguarding, experience and dissemination, and operation and development, to construct a spatial performance evaluation system for living heritage transmission. The Analytic Hierarchy Process (AHP) is adopted to determine the weight of each indicator. Taking the Yuezhou Fan ICH workshop as an empirical case, this study conducts a quantitative comparison of spatial performance before and after renovation. The results show that the comprehensive performance score of the workshop after renovation has increased by approximately 109.7% compared with that before renovation, among which the production and safeguarding dimension have the most significant improvement, verifying the rationality and practicability of the evaluation system. Theoretically, this study extends the application scope of built environment performance evaluation to the field of craft heritage spaces and establishes a closed-loop logic of “quantitative diagnosis—deficiency identification—targeted optimization” for workshop renovation. Based on the evaluation results, this paper proposes a progressive optimization path of “consolidating production baseline—upgrading experience scenarios—empowering diversified operation”, which provides a generalizable quantitative framework and practical reference for the spatial renovation and performance evaluation of similar craftsmanship-oriented ICH workshops.

The people-oriented city serves as the value orientation of urban work in the new era, and age-friendliness is precisely its core practical standard for intergenerational equity and inclusive sharing. Currently, the renovation of old residential areas should transcend single-dimensional physical patching and shift towards an all-age-friendly model that meets the complex needs of multi-age groups. Taking Tuanjiehu Communities in Beijing as a case study, this research constructs an evaluation system covering three dimensions—place, atmosphere, and culture—and 22 third-level indicators, and adopts the Semantic Differential Method (SD) and Analytic Hierarchy Process (AHP) to quantitatively analyze residents’ perceptions. The study finds that old residential areas generally suffer from problems such as “insufficient place safety and functionality, lack of atmospheric vitality, and weak cultural cultivation”. Based on these findings, a progressive renewal strategy of “Consolidating Safety Foundation → Boosting Community Vitality → Cultivating Community Culture” is proposed, offering an empirical illustration for the all-age-friendly renovation of high-density urban old residential areas to transform from “survival-oriented” spaces to “life-oriented” homes, offering preliminary insights for the all-age-friendly renovation of similar high-density urban old residential areas.

As China shifts from expansion-oriented urbanization to stock-based renewal, cities need diagnostic tools that can identify built-environment deficiencies and translate them into spatially targeted renewal priorities. Building on China’s official urban physical examination system, this study develops a land-renewal-oriented diagnostic workflow across four spatial scales: housing, community, block, and urban area. The framework integrates top-down objective assessment of land, facilities, infrastructure, environment, and safety conditions with bottom-up resident satisfaction evaluation. It then converts composite health scores, problem concentration, and safety relevance into three renewal priority categories: Priority Level III (critical renewal), Priority Level II (general renewal), and Priority Level I (long-term optimization). Using Wu’an, a resource-dependent county-level city in Hebei Province, as a case study, the results show that Priority Level III problems are concentrated mainly at the housing scale, especially corridor safety hazards, while widespread pipeline aging and age-friendly retrofitting needs are classified as Priority Level II medium-term renewal issues. Community and block scales mainly show facility, governance, and functional mismatches. The contribution of this study is not the four-tier scale structure itself, which is derived from existing policy, but the operational translation of urban physical examination results into spatial diagnosis for land renewal, renewal priority classification, and action-plan formulation. The workflow offers a transferable methodological reference for county-level stock renewal, while local indicators, thresholds, and implementation pathways require contextual adaptation.
