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].

Core Viewpoint - The article discusses the controversy surrounding the layout and density of the Shougang Jingyue Chang'an residential project in Beijing, highlighting concerns about insufficient spacing between buildings and the implications of the "good house" concept on actual living conditions and density [3][5][10]. Group 1: Project Overview - Shougang Jingyue Chang'an is located in Beijing's Shijingshan District and is noted as the first "good house" in the area, but it has been criticized for its tight building spacing [3]. - The project consists of 16 residential buildings ranging from 6 to 18 floors, with at least 7 buildings having very short spacing between them, with minimum distances of 9.96 meters and 9 meters [5]. - The site covers an area of 28,000 square meters with a total above-ground construction area of 75,900 square meters, indicating a rectangular layout [5]. Group 2: Density and Building Height - The maximum planned height for the buildings is 54.6 meters, which is below the allowed height of 60 meters (with some areas permitted up to 80 meters) due to concerns about sunlight impact on surrounding properties [5]. - The actual density of the project is higher than the stated floor area ratio (FAR) of 2.71, with calculations suggesting an effective FAR of 3.16 when accounting for non-counted areas [8]. Group 3: Non-Counted Areas - The project includes several types of non-counted above-ground areas, such as four ground-level voids totaling approximately 1,200 square meters and various balcony types that do not count towards the building's total area [6][8]. - The inclusion of these non-counted areas has led to an increase in the effective density of the project, raising concerns about the implications for living conditions [10]. Group 4: Market Trends - The article notes a broader trend in Beijing's real estate market where many new developments are incorporating high-gifted areas, leading to increased invisible density in residential projects [10]. - Since the introduction of the "good house" guidelines in November of the previous year, there has been a notable rise in the number of new projects featuring balconies and other non-counted areas, which may lead to tighter living conditions despite the perceived benefits [10].
