得房率超过130%？有些城市开始收紧了

Core Viewpoint - The article discusses the rising trend of "high usable area" in the real estate market, highlighting that developers are increasingly using this as a selling point rather than competing on price. However, this has led to questionable practices where developers manipulate measurements to inflate usable area figures [3][4][5]. Summary by Sections Regulation of Residential Area Calculation - Recent regulations from various cities, including Chengdu, have sparked discussions on "high usable area." Chengdu's new guidelines state that the horizontal projection area of balconies and other auxiliary spaces should not exceed 30% of the residential area, compared to the previous 20% limit [4][5]. - The new regulations aim to standardize the calculation of usable area and curb the excessive expansion of certain spaces like entrance halls, which were previously not included in area calculations [5][6]. Addressing Grey Areas - The article emphasizes that the goal of these regulations is to eliminate grey areas where developers might "steal area" by manipulating designs to increase the reported usable area. Common tactics include designing balconies as semi-enclosed spaces or mislabeling equipment platforms [8][9]. - The push for high usable area has led to inflated marketing claims, with some projects advertising usable areas exceeding 100%, which can mislead consumers [10]. Market Dynamics and Competition - The article notes that while high usable area projects have seen initial success, the market is becoming saturated, making it difficult for such projects to maintain sales momentum. For instance, a project in Wuhan with a 97-98% usable area only achieved an 18% sales rate [12][13]. - The competition among similar projects is intensifying, and developers are encouraged to focus on overall quality and sustainability rather than just maximizing usable area [14]. Future Directions - Experts suggest that the focus should shift from merely increasing usable area to enhancing overall living quality, including better community facilities and building standards. This approach aims to improve the long-term value of properties and the overall living experience [13][14].
