Renovation of Prefabricated Slab Houses in Hangzhou
The renovation of prefabricated slab houses in Hangzhou can be advanced through the establishment of self-renewal committees, leveraging policy support, drawing on successful case experiences, introducing social capital, and participating in micro-reform pilot projects. Details are as follows:
Establish self-renewal committees and apply for renovation projects
In August 2026, the 'Draft Regulations on Urban Renewal in Hangzhou' clarified that old residential communities could establish 'self-renewal committees'. These committees are organized by property owners who collectively apply to the construction authorities for renovation projects. After evaluation and approval, the projects are included in the urban renewal project database and receive policy support. This measure empowers property owners with leadership, stimulates residents' enthusiasm for participating in renovations, and provides institutional guarantees for renovation projects.
Leverage policy support to optimize renovation plans
For eligible self-renewal projects in old residential communities, Hangzhou allows for appropriate increases in floor area ratio, residential building area, and the addition of public service facilities. New housing units can also be included in the affordable housing range. For example, after the original demolition and reconstruction of Changcheng Jiaoyuan in Yuecheng District, Shaoxing City, more than ten new housing units were used as affordable housing, providing residents with more housing type options and balancing construction costs. This model offers valuable experience for the renovation of prefabricated slab houses in Hangzhou.
Draw on successful cases to drive project implementation
Hangzhou has already achieved successful practices, such as the Zhejiang Gongxin Community in Chaohui Subdistrict, Gongshu District. As the first pilot project for self-renewal of urban dilapidated housing in Zhejiang Province, four out of thirteen buildings constructed in 1983 were identified as Class C dilapidated housing. The project started in April 2023, with 548 households self-financing approximately 470 million yuan, accounting for more than 80% of the total reconstruction costs, and the government subsidizing the remaining portion through special funds. In February 2025, seven 11-story buildings with elevators were officially delivered. This case provides a replicable model for the renovation of prefabricated slab houses.
Introduce social capital to innovate renovation models
Hangzhou uses 'district planning schemes as guidelines and project implementation plans as handles' to coordinate district renewal resources and formulate an urban renewal project database. The residential renewal project in Hemu New Village, Hemu Subdistrict, Gongshu District, introduced social capital to participate in old renovations. Through measures such as adding value to old renovations, reducing living burdens, multiplying community co-construction, and dividing through digital empowerment, the community has been revitalized, injecting new vitality into the renovation.
Participate in micro-reform pilot projects to improve renovation efficiency
Zhejiang Province has launched micro-reforms for the renovation and renewal of old residential buildings, supporting five counties (cities, districts), including Xihu District in Hangzhou, to take the lead in pilot projects. It has collaborated with provincial state-owned enterprises to open 27 community-embedded 'light and fast renovation' stores in Hangzhou and other places, bringing full-process services closer to residents' daily lives. It has also guided private enterprises to launch standardized renovation packages in 'home improvement supermarkets', enabling transparent pricing and on-demand ordering by residents, thereby improving renovation efficiency and resident satisfaction.
