背景與挑戰——從100到0.1

北京老城是“都市計劃的無比杰作”。然而在近代，隨著城市人口增長和房屋產權歸屬變化日趨復雜，老城呈現產權碎片化和人居環境質量低下。主要挑戰包括居住面積狹小、基礎設施破舊、院內違建等。

策略與設計——0.1+｜-0.05

“0.1+”開間是老城居民的基本房屋產權單元，也是中國傳統木構建筑的基本空間單元，開間更新即在上述空間范圍內通過預制裝配式模塊置入實現生活核心功能最大化集成，并提出具有普適可能性的居住戶型改造方案。開間的尺寸具有一定規律，根據不同開間尺度和家庭情況，其內部空間設計可大致分為6 種類型。南鑼鼓巷雨兒胡同6 號院現有留住居民兩戶，項目在北房進行了試點建設。

“-0.05”通過精細化設計提高空間利用效率和品質，實現自愿違建置換和減量提質發展。在6 號院L 家的試點中，通過戶內復式家具置入，在不增加房本面積的基礎上使空間復合利用效率提高24%，戶主自愿拆除違建并獲得了更舒適的現代化生活。營造庭院花園并以鋼絲網對危墻進行保護隔離，開敞豁亮的院落煥發生機。

迭代與更新——從0.1到100

雨兒胡同6 號院采用裝配式建造，在院落內嚴苛的施工條件和緊張的工期要求下施工速度快、無噪音，對鄰里影響小，具有低成本、批量生產和推廣的可能性。以技術和政策創新賦能“0.1+”和“-0.05”不斷迭代，最終推進北京老城整體保護和人居環境改善。

Context and Challenges:From 100 to 0.1

Beijing's old city is an unparalleled masterpiece of city planning.However,the growth of urban population and the increasingly complex property rights since the modern era has led to the fragmentation and dilapidation of housing stock in the historic neighbourhoods.The prominent challenges include confined living space,shabby infrastructure and unauthorized constructions in the courtyard.

Strategy and Designs:0.1+∣-0.05

"0.1+":The Modular-bay is the basic unit of the housing property and a traditional Chinese timber column building.The Modular-bay upgrading is to insert prefabricated functional modules to maximize the integration of core living functions and to design the upgrading prototypes that can adapt to all modular-bay sizes.The specific size modes that Modular-bays follow and different households need has led to six applicable prototype products.We completed a pilot project in the north building in Yu'er Hutong 6# courtyard at Nanluoguxiang,where two households remained after the voluntary relocation.

"-0.05":The refined high-quality design helps residents utilize the space with efficiency and to fulfil their individual needs,encouraging voluntary replacement of unauthorized construction into space-conscious homes.In Mrs.L's home in the 6# courtyard,the space utilization efficiency was increased by 24% after upgrading,and she removed all unauthorized constructions and enjoyed a healthier modern life.Also,steel mesh wall was used to protect and isolate the dilapidated wall,and the courtyard garden is vibrant again with restored sunshine and ventilation.

Replicating and Regeneration:From 0.1 to 100

Showing high speed and low noise,the prefabricated construction in Yu'er Hutong 6# courtyard has successfully coped with strict construction conditions and tight construction schedule and minimized interruption to the neighbourhood.The Modular-bay upgrading has the potential of manufacturing at low cost and replication in hutong neighbourhoods.Empowered by technology and policy innovation,to scale up "0.1+" and "-0.05" will facilitate holistic conservation and rejuvenation of Beijing's old city.

評委評語

城市老舊住區的有機更新一直是城市發展過程中面臨的棘手問題。面對復雜產權背景、有限空間條件和人居質量需求、傳統合院保護之間的矛盾，“開間更新”從與居民平等的視角出發，切實理解他們在舊區生活中的實際困難和顧慮。設計著手于基礎空間單元“開間”，以簡明適用的空間模塊、可預制裝配的建造產品，能快速改善居民生活質量，也有助于合院公共環境修復，為整個舊區提供了適應性強、可復制、可推廣的人居方案，是體現設計服務社會公平的優秀實踐。

Jury Statement

The organic regeneration of old urban settlements has always been a difficult issue in the process of urban development.Faced with the contradiction between complex property rights,limited space conditions and the need for quality living and the preservation of traditional courtyards,"Modular-bay Upgrading" is designed from an equal perspective with the residents,understanding their practical difficulties and concerns in living in old districts.The design is based on the basic spatial unit "modular-bay",with simple and applicable spatial modules and prefabricated components.The design quickly improves the quality of life of the residents,and also contributes to the restoration of the public environment of the courtyard compound,providing a highly adaptable,replicable habitat solution for the whole district.It is an excellent design practice in the interest of social equality.□(Traslated by WANG Xinxin)
