成都拟出台新建住宅新规 提升得房率，用规划逼出好房子好小区

Core Viewpoint - Chengdu's Planning and Natural Resources Bureau has released a draft for public consultation regarding supplementary regulations for the "Chengdu Urban Planning Management Technical Regulations (2024)", aimed at supporting high-quality residential planning and construction management [1]. Group 1: Housing Design and Space Utilization - The draft specifies that the horizontal projection area of balconies, bay windows, and non-public activity spaces should not exceed 20% of the residential unit's building area, while the new regulations allow for a 30% limit on the horizontal projection area of various attached spaces [3]. - This change could increase the usable area of a typical 140 square meter unit by 14 square meters, potentially allowing for a "4+X room" configuration, thus improving the efficiency of space utilization [3]. - Balconies, whether enclosed or not, will be counted as half of their horizontal projection area in the floor area ratio calculation, allowing homeowners to enjoy larger balconies without compromising the building's exterior [3]. Group 2: Public Facilities and Community Amenities - The draft states that up to 1.5% of the total building area of a residential project, designated for shared facilities, will not be included in the floor area ratio calculation, promoting a win-win situation for developers and homeowners [4]. - Open-air rain corridors and non-motorized vehicle parking facilities will also be excluded from the floor area and building density calculations, encouraging developers to enhance community amenities [4][5]. - These regulations aim to improve the quality of life for residents by ensuring convenient access to services and amenities, such as easy access to package delivery [5]. Group 3: Electric Bicycle Parking Standards - The draft proposes a minimum of 0.5 electric bicycle parking spaces per household, with specific dimensions for each space, addressing the issue of chaotic parking and enhancing safety [6]. - This initiative aims to prevent electric bicycles from obstructing hallways and reducing fire hazards, thereby improving overall community safety [6]. Group 4: Innovative Housing Design - The draft encourages innovative housing designs by allowing for new planning requirements, such as high ceilings in living rooms and the use of eco-friendly materials, promoting the application of new concepts and technologies in residential design [6]. - This approach signifies a shift in focus from merely maximizing floor area ratios to enhancing the convenience of living, aesthetic design, and community functionality in future housing developments [6].
