重塑中庭空間，從天井到生動(dòng)的森谷

From Regular Courtyard to “Forest Valley”

博多森谷產(chǎn)業(yè)園位于杭州良渚新城，四座10—13層的L型布局高層辦公樓圍合出一處面積約4000平方米的中央庭院?？拷孛娴娜龑訛樯虡I(yè)空間，通過圍繞中庭的“回”字形連廊串聯(lián)。

Located in Liangzhu New City, Hangzhou, the Business Center of Boduo Sengo features four L-shaped high-rise office buildings enclosing a 4,000 sqm central courtyard. The lower three floors house commercial spaces interconnected by a loop corridor surrounding the courtyard.

業(yè)主期待中庭成為使用者共享的中心花園，但建筑基本落成后的空間體驗(yàn)并未充分滿足預(yù)期：串聯(lián)商鋪的筆直連廊缺乏變化，行走體驗(yàn)漫長而乏味；原有的中庭窄邊寬度僅為28米，塔樓則高約71米，中庭空間因此呈現(xiàn)天井式的壓抑觀感；冬季在中庭缺乏日照，陽光直射的月份則是杭州氣溫最為炎熱的夏季；在雨天，無遮蓋中庭的使用率也會(huì)急劇下降。

The owner envisioned the courtyard as a shared garden for all users, but the original space after construction fell short of expectations: The straight corridor linking shops lacks variation, resulting in a tedious walking experience. With a narrow width of 28m and surrounding towers reaching 71m in height, the courtyard evokes the constrained sensation of an enclosed well. Courtyard receives no direct sunlight in winter, while in summer—when Hangzhou experiences its hottest temperatures—the space suffers from intense solar exposure. During rainy days, the uncovered courtyard remains underutilized.

因此，業(yè)主希望通過一次高效率、短周期的更新，將項(xiàng)目重構(gòu)為宜人的空間。goa大象設(shè)計(jì)接受委托，承擔(dān)了中庭、入口與景觀的改造設(shè)計(jì)工作。對(duì)建筑師而言，博多森谷的改造是一次“非常規(guī)”的城市更新——目標(biāo)是建成不久的建筑，因此需要在減少干預(yù)既有結(jié)構(gòu)的基礎(chǔ)上進(jìn)行小范圍加建，但其效果必須足以令空間體驗(yàn)產(chǎn)生質(zhì)變。

Therefore, the owner aims to transform the complex into a pleasant space through a short-cycle renovation. GOA was commissioned to redesign the courtyard, entrances, and landscape. For the architects, this renovation project represents an unconventional urban renewal — targeting a recently completed building that requires minimal structural intervention yet demands qualitative transformations in spatial experience.

建筑師提出在中庭上空覆蓋一座透光的半開放天幕作為“頂棚”，以在提高耐候性的同時(shí)延續(xù)光照、空氣等開放空間的自然要素。在日照強(qiáng)烈的夏季，半透明的天幕可以濾過直射的陽光，并在庭院四邊入口處對(duì)流風(fēng)的吹拂下確保中庭涼爽舒適；在冬季，天幕則可以減少熱量散失以保持環(huán)境溫暖，并確保雨雪天氣時(shí)中庭空間的可使用性。

The primary challenge lies in enhancing weather adaptability while maintaining spatial continuity with the external environment. The architects proposed installing a translucent canopy over the courtyard as a "shelter". In summer, the canopy filters direct sunlight while allowing cross-ventilation from courtyard entrances, creating a cool microclimate. The structure also minimizes heat loss in winter and maintains usability during rain/snow through its thermal buffer zone effect.

鋼結(jié)構(gòu)與膜材料的協(xié)奏，賦予視覺平等權(quán)

Steel-Membrane Canopy

建筑師希望進(jìn)一步將中庭與環(huán)繞的商鋪一體打造成獨(dú)特的公共空間，而非辦公塔樓千篇一律的功能附屬，并為此轉(zhuǎn)向在地文化尋求靈感。以業(yè)主的品牌理念為出發(fā)點(diǎn)，受杭州周邊丘陵上起伏連綿、種植茶樹的梯田啟發(fā)，改造方案將天幕塑造成階梯般錯(cuò)落有致的“森谷”。在空間的水平邊界被辦公樓圍合限定的前提下，茶山般起伏的形態(tài)創(chuàng)造了豎向的空間變化，改善了行走與停留的體驗(yàn)。

Architects sought to integrate the courtyard with surrounding commercial areas into a distinctive public area by drawing inspiration from local culture. Starting from the client's brand philosophy and inspired by the terraced tea plantations on Hangzhou's hills, the renovation shapes the canopy into a "Forest Valley". The undulating terrace-like form creates vertical variations within the horizontally confined space defined by the surrounding buildings, improving experiences.

“茶山”賦予了園區(qū)使用者平等的視覺權(quán)利：天幕遮蔽了高聳的塔樓，在內(nèi)部感受到的中庭不再是狹窄壓抑的“天井”；四層以上面向中庭的辦公人群同樣獲得了宜人的視覺觀感，有如俯瞰碧綠的茶田。

The design also grants equal visual rights to all users: the canopy obscures the office towers, transforming the internal perception of the courtyard from a narrow "well" into a holistic space. Office workers above the fourth floor facing the courtyard also gain pleasant visual perspectives akin to overlooking verdant tea fields.

中庭天幕的造型設(shè)計(jì)復(fù)雜而精細(xì)。改造設(shè)計(jì)開始時(shí)項(xiàng)目已基本竣工，中庭的支撐結(jié)構(gòu)因此只能落在地下室的頂板上。為在有限的冗余荷載范圍內(nèi)實(shí)現(xiàn)設(shè)想，設(shè)計(jì)師選擇了輕質(zhì)的膜材料配合鋼結(jié)構(gòu)框架構(gòu)建天幕，其所需的結(jié)構(gòu)加固程度小于玻璃等傳統(tǒng)材料，可塑性強(qiáng)，并可以借助雨水沖刷完成自清潔，降低了日常維護(hù)成本。

The canopy's complex form demanded precise engineering. As the original construction was completed when the renovation began, the supporting structure had to be anchored to the basement roof. To realize the design within a limited load-bearing capacity, the team selected lightweight membrane materials combined with steel frames. This system required less structural reinforcement than traditional materials like glass, offered greater plasticity, and utilized rainwater for self-cleaning, reducing maintenance costs.

從空中俯視，天幕的膜材料為兩部分，強(qiáng)透光性的白色氣枕近似透明，將柔和的光影投射在中庭內(nèi)部；綠色的多層膜結(jié)構(gòu)則比擬茶山。如同張開的“陽傘”，以近似梯田的方式切分，層次間的空隙改善了中庭的通風(fēng)與排煙性能。

Aerial views reveal two membrane components: white transparent cushions projecting soft light into the courtyard and green multi-layered membranes evoking terraced tea plantations. Functioning like "parasols", the interlayer gaps improves ventilation and smoke exhaust.

設(shè)計(jì)團(tuán)隊(duì)與結(jié)構(gòu)顧問合作，解決了大跨度鋼膜結(jié)構(gòu)設(shè)計(jì)中的諸多技術(shù)難點(diǎn)：鋼結(jié)構(gòu)跨度大，截面形式多樣，整體呈曲面布置等。為了進(jìn)一步優(yōu)化設(shè)計(jì)，團(tuán)隊(duì)在局部采取了ETFE+PTFE雙層膜結(jié)構(gòu)，網(wǎng)格內(nèi)膜可以吸收噪聲，并提高能源利用效率。在多輪比選后，團(tuán)隊(duì)選定了50%、40%與35%透光率的三種綠色氣枕膜，依次分層布置，形成山水重疊般的漸變視覺效果。為避免積水，排水系統(tǒng)巧妙地隱藏于結(jié)構(gòu)內(nèi)部。天幕具有細(xì)微的坡度，可借助重力使雨水流向氣枕間的分縫并排向地面。

The architect collaborated with structural consultants to resolve technical challenges in the large-span steel-membrane structure design, including extensive span lengths, diverse cross-sectional forms, and curved configurations. To further optimize the design, a dual-layer ETFE+PTFE membrane system was implemented in specific areas, with the grid-patterned inner membrane providing noise absorption enhancement. After analyses, three green air-cushion membranes with 50%, 40%, and 35% light transmittance were selected, creating a gradient visual effect resembling an overlapping landscape. The drainage system was ingeniously concealed within the structure, while a subtle slope allowed gravity to direct rainwater through seams between cushions to the ground.

景觀與入口更新，親切不拒斥的城市界面

Welcoming Urban Interface

根據(jù)業(yè)主的設(shè)想，博多森谷的中庭將成為一片功能靈活可變的場地，平日作為商店的外擺區(qū)域，保留了拓展為可容納展會(huì)等聚集活動(dòng)的可能性。天幕覆蓋下，環(huán)繞原有建筑內(nèi)立面的外廊內(nèi)部挑出了露臺(tái)，成為了室內(nèi)空間自然延展，豐富了原本規(guī)整的方形空間。走廊轉(zhuǎn)角處的細(xì)致優(yōu)化使行走體驗(yàn)變得富有趣味。庭院內(nèi)部圍繞森谷的主題增添植被，和“茶山”共同形成自然溫馨的氛圍。

Per the client's vision, the courtyard will serve as a multipurpose space — functioning as extended seating for shops daily while retaining capacity for exhibitions and events. Beneath the canopy, terraces extending from the building's inner facades become natural spatial extensions, enriching the original square layout. Detailed optimizations at corridor corners create engaging circulation experiences. Themed vegetation enhances the "Forest Valley" concept, combining with the "tea mountain" forms to cultivate a natural ambiance.

原狀建筑在四個(gè)方向分別設(shè)有內(nèi)凹的入口。改造后的入口則通過大尺度的屋檐出挑，強(qiáng)化了空間特質(zhì)。與景觀花臺(tái)和水幕結(jié)合，引導(dǎo)訪客的視線與行走路徑。對(duì)于公共空間而言，讓來訪者感到“受歡迎”是必要的特質(zhì)。然而，原本的綠化設(shè)計(jì)中，建筑周邊被停車場與消防登高場地的硬化地面占據(jù)，往往需要繞過漫長的綠化帶才能找到入口。重新設(shè)計(jì)的景觀則實(shí)現(xiàn)了人車分流，重構(gòu)了建筑與城市的交界關(guān)系。

The original building featured entrances on four sides. After renovation, the entrances now emphasize spatial identity through cantilevered eaves, integrated with plants and water curtains to guide visitors’ sight and path. While accessibility is essential for public spaces, the original site was dominated by parking lots and fire access zones, forcing pedestrians through lengthy green buffers. The redesigned landscape achieves pedestrian-vehicle separation, redefining the building's urban interface.
