Group 1 - The first fourth-generation residential project in Tianjin has been constructed, raising questions about its authenticity and quality [1][3][7] - The project features a balcony depth of 2.5 meters, meeting the minimum requirement, but lacks significant differentiation from traditional residential designs [3][6] - The expected efficiency rate of the new project is likely below 100%, contrasting with the high efficiency rates seen in other cities [6][14] Group 2 - Tianjin's fourth-generation residential regulations have been slow to materialize, with no authentic projects launched despite the announcement of pilot regulations over six months ago [7][9] - The city is cautious about the impact of high efficiency rates on existing properties, leading to a compromise in the design and implementation of new residential projects [9][14] - Other cities, such as Guangzhou, are tightening regulations on efficiency rates to prevent market disruptions, indicating a broader trend in the real estate sector [15][24] Group 3 - The rapid evolution of residential designs is causing significant depreciation in the value of older properties, as seen in Guangzhou where efficiency rates have led to drastic price drops [19][22] - The competitive nature of high efficiency rates is creating a cycle of market instability, affecting both new and second-hand property prices [24][30] - The current market conditions suggest that new residential projects in Tianjin will not see further increases in efficiency rates, as regulations are tightening to stabilize the market [30][31]
