This paper studies the spatial forms and cultural sustainability of the Damazhan and Xiaomazhan historical area, the only area that reflects the development of the assembled-clan hall culture in Guangzhou. In the face of modernization and reconstruction, traditional culture plays an increasingly crucial role in modern cities, determining the expression of architectural uniqueness and continuous development that adapts to social needs. Therefore, preserving cultural characteristics is more relevant than ever. This study combines historical literature research with typo-morphological analysis to establish analytical strategies that link cultural sustainability with spatial evolution from the perspective of sustainable development. The analytical framework consists of three parts: First of all, through historical literature research, a thorough analysis is conducted on the cultural and social influencing factors from the Dynasties of Song, Yuan, Ming, Qing and the Republic of China to the reform and opening up period. Secondly, feature elements of the location are extracted, and a typo-morphological approach is used to analyze the sustained changes in spatial forms. Finally, the relationship between changes in block form and building types and the inheritance and development of traditional culture are demonstrated. The analytical results indicate that the continuity of cultural characteristics is embodied in the continuity of the block and architectural spatial characteristics, while cultural transformation and man-made social factors affect the changes in spatial forms. This paper combines the perspective of cultural sustainability analysis with the traditional typo-morphological approaches of urban spatial analysis, supplementing the existing typo-morphological methodology. In addition, guiding the development of urban morphology from the perspective of cultural sustainability is of prominent practical significance.

The rise in aging world populations poses enormous concerns, among which is the critical topic of how to promote active aging by improving the health and well-being of the elderly. Accordingly, installing elevators in old residential buildings has become a main issue in age-friendly community regeneration to make it easier for the elderly to go outside. There is limited evidence on stakeholder involvement in age-friendly community regeneration. Some studies have overlooked the fact that fostering age-friendly communities in developing countries requires innovative governance for inclusive physical and social features despite the low awareness of citizen engagement. With reference to community governance as a structure and process, a theoretical framework is proposed to understand the practice of elevator installation in age-friendly community regeneration in Guangzhou, China. This study adopted the questionnaire survey method and collected 455 valid samples (150 valid samples with installed elevators; 305 valid samples did not install elevators). The findings led to the following conclusions: (1) shared common interests lead to effective community governance and smooth elevator installation; (2) some communities failed to install elevators due to opposition from people whose interests were hindered; and (3) it is important to set up self-governing organizations and find key people in community governance for interest-based negotiation. This paper’s contribution is that it makes up for the deficiency in the previous research that has neglected the elderly’s participation in public affairs via age-friendly community regeneration. Finally, this study suggests further research on the dynamic processes of different types of age-friendly community regeneration affairs.
