首钢璟悦长安亮相，杜林巍造了“枪版”户型

Core Viewpoint - The article discusses the unique characteristics and potential issues of the Shougang Jingyue Chang'an residential project in Beijing, highlighting its design flaws and the implications for buyers [2][3][4]. Group 1: Project Overview - Shougang Jingyue Chang'an is notable for its architectural features, including four ground-level voids and south-north embedded balconies [2]. - The project consists of 700 units, with a specific focus on a unique "gun-shaped" unit type measuring 95 square meters, which is a small fraction of the total [3][4]. Group 2: Design Issues - The project suffers from a high density of buildings, leading to unconventional unit designs, such as the "gun-shaped" layout, which negatively impacts the overall quality perception [4][6]. - The design includes 24 east-west facing units, which further detracts from buyer appeal due to their awkward configurations [4][6]. Group 3: Unit Specifications - The "gun-shaped" unit features a total of 10.2 square meters of free area, resulting in a gift area ratio of 10.74% [7][8]. - The unit faces significant issues with southwest sun exposure, affecting comfort levels [8]. - The layout presents challenges, such as a poorly positioned main entrance and a lack of natural light in the foyer [8][9]. Group 4: Building Parameters - The project occupies an area of 28,000 square meters with a total above-ground construction area of 75,900 square meters, resulting in a high floor area ratio of 2.71 [10]. - Due to concerns about sunlight for adjacent buildings, the maximum building height is limited to 54.6 meters, despite a potential height of 60 meters [10][13]. - The inclusion of non-countable building areas, such as ground-level voids and balconies, has increased the effective floor area ratio to 3.16 [13][16].
