广州楼市“掀桌子”！明年起，你买的新房全是“拼装预制房了”

Core Viewpoint - The article discusses the shift towards prefabricated and modular construction in Guangzhou, highlighting the city's plans to implement these methods in residential buildings starting in 2026, with a target of achieving a total output value of 500 billion yuan by 2030 [1][3]. Group 1: Policy and Implementation - Guangzhou's new policy mandates that from 2026, all residential land sold will utilize prefabricated construction methods, with at least 10% of land each year required to implement modular building techniques, increasing to 80% by 2030 [3]. - The city aims to modernize the construction industry, with a projected total output value of 500 billion yuan for the smart construction and industrialized building sector by 2030 [1]. Group 2: Construction Methodology - The new construction method involves producing prefabricated rooms in factories, which are then transported to construction sites for assembly, while the foundation and main structure will still be poured on-site [3][5]. - As of 2023, prefabricated construction methods accounted for 48.42% of total construction in Guangzhou, with certain districts exceeding 50% [3]. Group 3: Benefits and Concerns - Advantages of prefabricated buildings include a 30% reduction in construction time, less construction waste, and improved environmental conditions due to reduced noise [11]. - Concerns raised by the public include potential quality issues, higher costs due to the need for customized models for different housing types, and the impact on traditional labor markets as construction becomes more automated [6][8][13].
