The Transformation Mode of Historical and Cultural Blocks and Its Enlightenment

The transformation of Yongqingfang has gone through three stages: "retrofitting", "focusing on historical and cultural values", and "micro-transformation". The main mechanism of the "micro-transformation" model refers to the guiding principles and practical paths. The guiding principle includes "government-leading, enterprise undertaking, and public participation". The practice path is to strive to preserve the original block layout, implement "embroidered" transformation, and carry out the appropriate demolition and repair of the original buildings. In order to meet the needs of modern activities, the internal structure of some buildings is carried out on the basis of not changing the external shape of the block building. On the premise of preserving the original style of the block, it is important to optimize the public service facilities and revitalize and update the business and culture in the block, so that the ancient street can restore the commercial and cultural vitality. By sorting out the micro-transformation model of Yongqingfang, three enlightenments can be drawn that are beneficial to the transformation of the historical and cultural street. That is, it is suggested to balance the interests of investors and the interests of residents during the transformation, balance the inheritance and innovation, and do well in the integration and balance relationship between culture and industry.
