Beijing has released the local version of the Residential Design Specification (hereinafter referred to as the "Specification") for the first time. After soliciting opinions, the Municipal Planning and Natural Resources Commission will revise and improve it. After its official implementation, Beijing will use this standard to regulate and guide residential design throughout the city.


The minimum cover area is 24 square meters


Based on the actual situation in Beijing, the Beijing version of the "Code" has compiled a total of 345 clauses, of which more than 200 clauses have been adjusted and supplemented on the basis of the national standard "Code", and many residential details have been improved. For example, in the national version of the "Regulations", the minimum cover area is 22 square meters, while in the Beijing version of the "Regulations", the minimum cover area is set at 24 square meters.


"Although it's only 2 square meters away, the living experience for small units is completely different. The reason why the Beijing version of the" Regulations "is so fixed is mainly because people's living needs have gradually shifted from meeting basic needs to comfortable living. Based on project summary and field research, combined with engineering data and experience, the requirements for the use area of the main functional spaces of the bedroom, living room (hall), kitchen, and bathroom have been increased." The relevant person in charge of the Municipal Planning and Natural Resources Commission said.


Specifically, the required usage area for the bedroom and living room should be increased by 1 square meter, while the required usage area for the kitchen and bathroom should be increased by 0.1-0.5 square meters. According to the increase in the required usage area of different functional spaces, the minimum usage area of the suite has also been increased. "The additional 2 square meters are a sign of care for residents of small apartments," said the person in charge.


Residential floor height not less than 2.8 meters


The Beijing version of the "Regulations" has raised the floor height standards for residential spaces, requiring residential floors to be no less than 2.8 meters high and ensuring that the indoor net height is no less than 2.5 meters.


"Due to various considerations such as the application of residential floor heating, prefabricated structural forms, same floor drainage in bathrooms, and the increase in per capita height and ergonomics in China, the" Code "has increased the values of residential floor height and net height to ensure a reasonable net height indoors, in order to truly meet the comfort of living.".


In addition, considering various factors such as residential safety and unified standards, the "Code" also sets the height of balcony railings to be uniformly set at 1100mm and requires them to be completely firm.


"We have conducted a refined 'comb style' scan of the key points of residential design, not neglecting every detail, especially the practical problems such as kitchen skewers, bathroom floor drains, high noise from drainage pipes, and waste in secondary decoration that have been frequently reported by the public. This time, we have solved them in a package through special research and breakthroughs one by one." The relevant person in charge mentioned above introduced.


To this end, the Municipal Planning and Natural Resources Commission organized experts and relevant units to conduct multiple thematic studies in order to find the most suitable scheme as the standard.


Taking drainage issues as an example, relevant experts compared various methods based on engineering examples, and through experiments and follow-up visits, ultimately recommended using the same floor drainage method in the bathroom.


Emphasize aging friendly design for elevators, handrails, etc


At present, China has entered an aging society, and more attention should be paid to the elderly population in all aspects of housing, which is also reflected in the Beijing version of the "Regulations".


For example, the original regulation of "installing elevators on floors seven or more or on the entrance floor of residents with a height exceeding 16 meters from the outdoor design ground" has been adjusted to "installing elevators on new residential buildings with four or more floors or on the entrance floor of residents with a height exceeding 9 meters from the outdoor design ground".


In addition, residential units equipped with elevators should have at least one elevator that can accommodate stretchers, and the size of the elevator car should not be less than 1.50m x 1.60m, and the net width of the car door should not be less than 0.90m.


Adapting to aging is a systematic engineering project. In addition to setting up elevators, the Beijing version of the "Regulations" also includes a series of contents such as setting up emergency call devices, installing handrails, and accessibility facilities.


For example, the size requirements for the inner passage and door opening width have been increased to ensure unobstructed passage width inside the sleeve; The public entrance hall is equipped with wheelchair turning space; Strengthen various preventive measures, such as reserving and installing handrails and emergency call devices in residential bathrooms, bedrooms, etc., to ensure the safety of daily life for people with limited mobility.

What are the characteristics of the Beijing version of the Code compared to the national version?


Previously, Beijing had been implementing the national version of the "Regulations" for a long time.


After years of practice and revision, the national version of the "Code" has become more comprehensive and detailed. However, in practice, there are still some practical problems that need to be further clarified and refined in combination with the actual situation in Beijing and the needs of the people for housing. Therefore, the Beijing Municipal Commission of Planning and Natural Resources carried out a series of targeted special investigations and studies, soliciting opinions from other relevant units, and based on the national version of the "Norms", organized the compilation of the Beijing version of the "Norms".


Compared with the national version of the Code, the Beijing version of the Code has added three major chapters on residential facilities, building structures, and pipeline integration, as well as nine sub sections on fire protection construction, insulation and thermal insulation, power supply and distribution design, lighting facilities, lightning protection and grounding, information infrastructure systems, public safety systems, smart home systems, and electrical energy-saving design. Nearly 300 clauses have been modified and supplemented. It embodies the three major concepts of "safety, comfort, and foresight", implements five requirements of "aging adaptation, industrialization, standardization, intelligence, and greening", and is more refined, targeted, and operable.

Does the Code have strong execution power?


Firstly, as a local standard in Beijing, the Beijing version of the "Code" is a legally effective technical document published in the form of standard specifications. It is the basis for the design industry to carry out residential design work and also the basis for government approval. It has strong execution power and is a standard that must be followed by the residential design industry.


Secondly, the "Norms" will start from solving the problems existing in the actual use and design of residential buildings in Beijing, with the basic principles of improving residential safety, enhancing residential comfort, advocating green and energy-saving, valuing accessibility and aging friendliness, advocating full decoration, facilitating design and use, and considering design foresight.

Many contents of the "Code" are specified in great detail, why?


The compilation of this "Code" focuses more on details and operability, and comprehensively applies advanced new technologies, new processes, new materials, and new products from home and abroad in technology, promoting the process of residential standardization and leading the new trend of residential design nationwide.


All contents and details related to residential buildings are detailed in the "Code". The reason for such refinement is twofold: firstly, it solves some long-standing design difficulties and ambiguities, which provides more guidance for residential design; The second is to solve the problems that arise in residential buildings and eliminate them from the source; The third is to fully consider the entire life cycle of the residence, reserve conditions suitable for aging, accessibility and other changes, and prepare for the future.
