有专家说出实话：10年后，二三十层的高层住宅，将面临3大难题

Core Viewpoint - High-rise residential buildings, once desirable, are facing significant challenges that may lead to their obsolescence in the coming decade due to issues like high shared areas, elevator maintenance, and overall building aging [1][26]. Group 1: Shared Area Issues - The problem of shared area is often overlooked when purchasing a home, with many high-rise buildings having up to 25% of the total area as shared space, resulting in only 75 square meters of usable space from a 100 square meter purchase [3][5]. - The financial burden of these shared areas accumulates over time, leading to additional costs for heating, property management, and waste disposal, which can amount to tens of thousands over the years [5][7]. - The market is becoming increasingly resistant to properties with high shared areas, as low usable space not only affects current living conditions but also diminishes future resale value [7]. Group 2: Elevator Challenges - Elevators, initially a source of convenience, become a significant concern as they approach the end of their 15-20 year lifespan, leading to frequent malfunctions and costly repairs [8][10]. - The cost of major elevator repairs can start at 300,000 yuan, with complete replacements costing upwards of 500,000 yuan, which can total over a million for multiple elevators in a building [10][12]. - The rising proportion of elderly residents in high-rises exacerbates the issue, as elevator failures can severely impact their mobility and quality of life [14]. Group 3: Building Aging Crisis - Concerns about building safety, particularly in emergencies like fires, are growing, as many high-rises are not equipped to handle such situations effectively [16][19]. - The internal structure of high-rises can create a "chimney effect" during fires, rapidly spreading smoke and making evacuation difficult [16][17]. - External building maintenance issues, such as deteriorating facades and aging infrastructure, pose additional risks, with residents often left to manage these problems themselves due to insufficient support from property management or government [19][21]. Group 4: Recommendations for Future Management - To mitigate risks, potential buyers should focus on properties with lower shared areas and higher usable space, as well as closely monitor elevator conditions and maintenance records [22][24]. - Awareness of government policies supporting elevator maintenance and updates can help reduce financial burdens on residents [24]. - Community involvement in safety practices, such as keeping fire exits clear and participating in fire drills, is crucial for enhancing overall safety in high-rise living environments [24][26].
