杭州最早的高层商品房小区迎来旧改，总投资约2700万元

Core Viewpoint - The renovation of Zhongshan Garden, one of Hangzhou's earliest high-rise residential complexes, marks the beginning of a broader initiative to upgrade aging residential buildings in the city, reflecting a growing trend in urban renewal efforts [1][4]. Group 1: Renovation Details - The renovation project includes structural, installation, decorative, outdoor, weak current, and fire safety engineering, with a significant focus on the exterior facade and fire safety upgrades [8]. - The total estimated investment for the renovation is approximately 27 million yuan, with 16 million yuan allocated for the exterior work alone [9]. - Homeowners are required to cover 10% of the exterior renovation costs, amounting to 1.6 million yuan, which translates to about 2,800 yuan per household, although this cost is being covered by the community's maintenance fund [12]. Group 2: Historical Context and Future Implications - Zhongshan Garden, built in 1993, was once a prestigious residential area but has since deteriorated, leading to strong homeowner demand for renovation [4][9]. - The renovation is part of a larger initiative in Hangzhou, which has seen two rounds of old residential community upgrades since 2019, with plans to complete renovations for all buildings constructed before 2000 by the end of this year [17]. - Future renovations may expand to include buildings constructed after 2000, indicating a potential shift in urban renewal strategies [17].
