10年后，国内二三十层的高层住宅，不得不面临的很真实3大难题！

Core Viewpoint - The real estate market in China is facing significant changes in supply and demand dynamics, necessitating policy adjustments to address emerging challenges in high-rise residential buildings [1][3]. Group 1: Market Data - By 2019, the home ownership rate among urban residents in China reached 96%, with an average of 1.5 homes per household, and over 40% of families owning more than two homes [3]. - As of July 2023, the total unsold commercial housing area in China was 640 million square meters, a year-on-year increase of 17.9%, approaching levels seen during the 2015 inventory reduction period [3]. - The average living space per urban resident is nearly 40 square meters, surpassing that of developed countries in Europe and America [3]. Group 2: Issues with High-Rise Residential Buildings - High-rise residential buildings face three major challenges in the next decade: quality issues, maintenance problems, and demolition difficulties [6][8]. - Quality issues are exacerbated by the downturn in the real estate market, leading to financing difficulties for developers and subsequent deterioration in construction quality [8]. - Maintenance of essential systems such as elevators, plumbing, and fire safety becomes problematic as these systems age, and reliance on public maintenance funds may not be sustainable [8]. - Demolition costs for high-rise buildings are prohibitively high, making it difficult for developers and local governments to manage aging structures, with significant financial implications for potential redevelopment [10].
