保利半壁店豪宅，谜底揭晓

Core Viewpoint - The development of the "Banbidian Twins" project in Haidian, Beijing, is progressing slowly, with significant attention on its planning and construction parameters, particularly regarding building height and floor area ratio [3][4][5]. Group 1: Project Development Progress - The project company, Beijing Huihai Changzhu Real Estate Co., has issued two construction tender prequalification announcements with an estimated contract value of 721 million yuan, indicating progress in the "Banbidian Twins" project [3]. - The project is a joint venture between Poly Development (holding 70%) and Beijing Construction Real Estate (holding 30%) [3]. - The development process typically requires the issuance of planning maps, obtaining planning permits, and then construction permits, suggesting that the project still has a long way to go before completion [4]. Group 2: Planning Parameters - The floor area ratios (FAR) for the two plots are set at 1.42 and 1.44, with the project located approximately 500 meters from the Fourth Ring Road, making it a prime location in Haidian [7][8]. - The land was acquired for 4.545 billion yuan, translating to a floor price of approximately 78,400 yuan per square meter, with a premium rate of 11.95% [9]. - The two plots have been allowed to have their FAR and green space ratios calculated together, enhancing development flexibility [10]. Group 3: Building Height and Design Considerations - The building height is currently uncertain, with a maximum height of 18 meters indicated, but subject to final approval [16][18]. - The project may consider a design similar to other successful developments in the area, focusing on large flat units rather than stacked villas, especially if the height is confirmed at 18 meters [23]. - The proximity to the airport, only 2 kilometers away, may influence buyer preferences and design choices for the project [23].
