Core Viewpoint - The emergence of the "fourth generation residential" in Wenzhou signifies a new wave of housing product iteration, raising questions about the long-term value of existing properties and the future of housing development in the region [1]. Group 1: Current Housing Landscape - Wenzhou has a history of poorly planned "ground-level houses" that have been largely demolished in recent years due to their low quality and chaotic layout [2]. - Many of these ground-level houses remain, particularly in historical cultural districts, where they may be preserved for their cultural value [3]. - Outside historical districts, most ground-level houses in urban villages and suburban areas are expected to face demolition in the long term, although some areas may take decades to see changes [5]. Group 2: Historical Development of Residential Properties - Since the 1980s, Wenzhou has seen the construction of multi-story residential buildings, initially referred to as "new villages," which often lacked basic amenities like elevators [7][13]. - By the 1990s, the quality of these buildings improved slightly, with some using exterior wall bricks, but many still lacked modern features [10][14]. - High-rise residential buildings began to emerge in the late 1990s, but many were still mixed-use and lacked the modern amenities that define contemporary residential complexes [16][19]. Group 3: Evolution of Quality and Design - Starting around 2005, Wenzhou saw the rise of quality residential properties characterized by better landscaping, vehicle separation, and modern architectural styles [22]. - The introduction of luxury properties with glass curtain walls marked a significant shift in design, enhancing the city's image [24][33]. - By 2021, the market faced a downturn, prompting developers to focus on luxury features and amenities to attract buyers [35]. Group 4: Future Trends in Residential Development - The "fourth generation residential" concept aims to enhance living spaces through features like sky gardens and low-density designs, which could redefine the housing market [36][38]. - The success of these new developments will depend on quality maintenance and management, as well as the ability to preserve aesthetic appeal [38]. - As the "fourth generation residential" becomes prevalent, older properties lacking desirable locations or amenities are likely to decrease in value [39].
