最小

北京老城在近當代由于人口激增和管理運維能力不足等原因，呈現(xiàn)出高密度、低質量、產(chǎn)權復雜化以及空間碎片化的人居環(huán)境狀態(tài)。隨著老城整體保護的日趨嚴格和居民物權意識的日益增強，曾經(jīng)的房地產(chǎn)開發(fā)帶動危舊房改造的大拆大建模式難以為繼，逐漸轉向面對單個院落乃至房屋的城市微更新。在此背景下，本項目提出的“最小”是指在“開間”這一老城最小的產(chǎn)權單元與空間單元之內，探索適宜于低收入居民的人居改善設計。

最大

為低收入居民的設計，不同于那些或紳士化或公益性的單件作品創(chuàng)作，應努力將“最小”迭代推廣到“最大”。最大化的一方面在于設計的產(chǎn)品化，能夠靈活適應于眾多不同使用者的需求，且有利于控制成本和便捷安裝；另一方面在于設計應尊重產(chǎn)權和厘清產(chǎn)權，既要防范違法建設蔓延所帶來的物質環(huán)境過載和規(guī)則意識崩塌，又能有利于人性化地拆違執(zhí)法，區(qū)分出低收入居民并予以幫助，方能形成“最大”推廣。

“開間更新”家

“開間更新”指在開間產(chǎn)權單元內提出6種不同的家庭空間類型，分別適用于面寬、進深不同的尺寸區(qū)間，以及適應于單代或多代不同的家庭結構?！伴_間更新”包含整合了水電氣設施入戶的集成衛(wèi)生間、廚房、樓梯及收納模塊，并將其預制化、產(chǎn)品化，以保證質量、控制造價和減少施工干擾。同時可通過坡屋面下夾層設置和地面淺下挖來提高空間利用率。與開發(fā)企業(yè)的民宿短租和業(yè)態(tài)混合產(chǎn)品不同，也與高收入居民大套或多套住房的持有相區(qū)別，本項目充分指向低收入居民的長住需求及其保障。

“模塊置換”院

“模塊置換”指建議在院落內配租公租模塊，以容納有限的開間內所無法承載的廚衛(wèi)或收納功能，同時置換拆除原有的院內違法建設。這些公租模塊應產(chǎn)權清晰，由政府所有，統(tǒng)一進行集約的、可逆的、與老城風貌相協(xié)調的標準化設計和裝配，同時制定租金和物業(yè)服務管理的費用及補貼標準。居民可根據(jù)需求進行模塊選擇和組合。這些模塊未來隨著居民生活方式的改變以及租金的動態(tài)調整，將逐漸退出老城，最終實現(xiàn)以柔性而非強制拆除的手段，恢復四合院內健康有序的空間格局。

福綏境胡同50號院

在北京西城區(qū)政府、北京華融金盈投資發(fā)展有限公司的委托和執(zhí)行支持下，“開間更新”在福綏境胡同50號院進行了試點建設。項目2017年9月參展北京國際設計周，同年11月獲拉法基豪瑞全球可持續(xù)建筑獎亞太區(qū)榮譽提名獎。福綏境50號院在設計、施工過程中及竣工以來，持續(xù)開展居民的公眾參與和研討，并于2018年1月起面向有意向的居民進行試住體驗，收集試住反饋、不斷完善設計，積極推動成果的推廣應用以及相關政策機制的制定實施。□

The minimum

In the recent years, the old city of Beijing has shown a living environment state of high density, low quality, complex property rights and fragmentation of space, due to reasons such as the surge of population and lack of management and operation ability. As the overall preservation of the old city becomes more stringent, and the residents' awareness of property rights grows stronger, the old mode of large-scale demolition and reconstruction,in which the real estate development dominated the reconstruction of old houses, is no longer sustainable, and has been gradually turning into a kind of micro renewal of the city, which focuses on single courtyards and even houses. In this context,the "minimum" in this project refers to the "bay"(kaijian), the minimum unit of property rights and space in the old city, and within, to explore the design of residential improvement suitable for lowincome residents.

To maximise

Designing for the low-income residents is different from designing single projects for gentrification or public welfare, the"minimum" should be strived to extend to the"maximum". One aspect of the maximisation is the productisation of the design, which can adapt to the needs of many different users, and is conducive to cost control and convenient installation; the other aspect is that the design should respect and clarify the property rights, not only to prevent the overload of material environment and the collapse of rule consciousness brought by the spreading illegal construction, but also to make it easier for humanised demolition and law enforcement,distinguishing low-income residents and helping them, so that it's possible to form the "maximised"promotion.

Bay-unit homes for the low-income

"Bay renewal" refers to the proposed 6 different types of family space in the unit of property rights, which are suitable for different dimension intervals of width and depth, and suitable for different family structures of one or more generations. The "bay renewal" includes integrated modules of toilet, kitchen, staircase and storage which contained in-house water and electrical facilities, and makes them prefabricated and productised to ensure the quality, control the cost and reduce the construction disturbance.At the same time, the space utilisation rate can be increased through the setting of mezzanine under the pitched roof and the shallow digging of the ground. Different both from the developers' products of short rents and mixed business and from the high-income residents' holdings of large or multiple housing, this project totally aims at the long stay demand and security of the low-income residents.

Courtyard modules to dissolve the illegal

"Module replacement" refers to the suggestion of public rental modules be set in the courtyard, to accommodate the functions of kitchen, bathroom and storage which cannot be loaded within the limited space of bay, and to replace the original illegal constructions in the courtyard. This public rental module should be owned by the government with clear property rights, who will carry out standardised design and assembly with integration, reversibility, and coordination with features of the old city, as well as settling the standards for the prices of rent and property service management, and subsidy.Residents can select and combine modules according to their needs. With the change of residence life style and dynamic combination of rentals, these modules will gradually withdraw from the old city and finally restore a healthy and orderly spatial pattern in the courtyard by means of flexibility rather than forced demolition.

No. 50 Fusuijing Hutong pilot project

Under the commission and operative support of Beijing Xicheng District Government and Beijing Huarongjinying Investment Development Co., Ltd.,"bay renewal" was experimentally carried out in Courtyard No. 50, Fusuijing Hutong. In September 2017, the project participated in the Beijing International Design Week. Same year November,it won the honorary nomination award of Lafarge Holcim Awards for Sustainable Construction in the Asia-Pacific area. In the course of design,construction, and use after completion, No. 50 Fusuijing has been continuously involving public participation and discussion of the residents, opened to interested try-out residents since January 2018 to collect feedback and continue to improve the design, encouraging the promotion and adjustment of the feedback for relevant policies.□(Translated by CHEN Yuxiao)

評論

石克輝：白塔寺地區(qū)混雜、擁擠的“大雜院”被設計者精簡地用“最小”與“最大”的概念提取出來。用大雜院里地“開間”這個“最小”空間為單位進行了街區(qū)的人居改造，探索空間使用的效率和舒適度，同時模塊置換的手法也讓改造過程更加柔和與容易，空間單位的組合也更加靈活，但從“最小”到“最大”推進的過程中，缺少了對于高密度居住空間中集體交往空間的探討，對“最大”的詮釋不夠清晰。

Comments

SHI Kehui: The messy and crowded "compounds" in Baitasi area are condensed into the concepts of "minimum" and "maximum"by the designer. The design uses the "bay" (kaijian), the minimum space in a compound, as the unit of human settlement renewal in the block, in order to explore the degree of efficiency and comfort in spatial use. Meanwhile, the application of the module replacement method makes the renewal process gentler and easier, and the combination of spatial units is more flexible. But during the process moving from "minimum" to "maximum", the exploration on the collective interaction space in high-density living space is lacked, so the interpretation of "maximum" is not so clear.

鮑威：胡同改造從來不是單純的設計問題，而是關乎產(chǎn)權歸屬、鄰里關系、社區(qū)功能等一系列問題協(xié)調的產(chǎn)物。本案學院派的處理方式也是醉翁之意不在設計本身，而是試圖探討胡同居住改造的普適策略。研究準確地抓住了“開間”這個最小空間載體，提出了6種家庭類型的模型，這一系統(tǒng)具備推而廣之、波及整個舊城的潛力。這種抓主要矛盾、小中見大、由此及彼、從單到多的策略是張悅老師多年來競賽的一貫策略，也在這個小型改造項目中發(fā)揮得淋漓盡致。

BAO Wei: Hutong renewal is never a pure design issue, but a product of coordination of a series of problems like property ownership,neighbourhood relationship, community functions, etc. The real intention of this academic design is not about the design itself, but an attempt to explore the universal strategy for housing renewal in Hutong. The design precisely focuses on "bay", the smallest spatial unit, and puts forward six modules for different family types. The system has the potential of being widely promoted and applied in the whole old city. Prof. ZHANG Yue adopts a strategy of concentration on the primary contradiction that sees the whole picture from small points and proceeds from one point to another from single to multiple levels for many years in competitions, as brought into full play in this small-scale renewal project.
