譚崢：坡屋面定律

坡屋面是當代建筑中常被誤用的元素，當屋面的坡度脫離了傳統的結構、功能與儀式的限定后，極易淪為符號與裝飾。坡屋面的“破局”有如下選項——或重構一種非垂直-水平體系的地形；或重建認知、身體與空間對象的關系；或定義空間的向背、動靜、親疏關系。華之毅時尚藝術中心的坡屋面正回應了上述的幾個對策，客觀上它延續了一個關于坡屋面的建筑學研究綱領，并探索坡屋面的當代運用定律。

華之毅時尚中心運用其螺旋上升的坡屋面重構了場地地形，在一整體屋檐下協調了因功能需要而高度、體量迥異的單體建筑，并界定了一個有彈性邊界的內向庭院空間。在緊張的基地條件約束下，整個建筑群被設計為一個合院，4棟單體分別由4幅不同坡度的內向單坡屋面覆蓋，屋面相對墻體均有不同程度的延展，四側屋面呈螺旋式依次降低，最后在內院變成地下訂貨大廳的屋頂，事實上融為地形的一部分，屋面的坡度也隨之依次趨向平緩舒展，至東側坡屋面則最迫近身體的高度，以一種更親和的姿態歡迎訪客。東與北側兩幅屋面相交處的“裂縫”也呼應了這一進入方向，“裂縫”之下是深遠出檐下的寬適入口空間。

整個混凝土梁柱及樓屋面體系預期采用竹篾紋模板澆筑，柱間部分與屋架底均使用高性能竹基纖維復合材料（竹鋼）百葉圍護，柱間的竹鋼百葉呈規律的折線波浪形，與幕墻形成雙層圍護體系，混凝土的粗糙與竹鋼的纖柔因其共同的竹紋理而統一。整個建筑群的屋頂用傳統的望板裸筑，這是有意識地與已經被符號化的瓦屋面保持距離，三號樓的坡屋面局部打開，為所覆蓋的屋頂花園提供自然采光，這一處理手法與地下訂貨大廳的光井（小下沉庭院）形成呼應，更貫徹了坡屋面與場地地形的融合規律。

TAN Zheng: Rule of Pitched Roofs

Pitched roof is a commonly misused element in modern architecture. When pitched roof is derived from the limitation of traditional structure, function and rite, it's very likely to become a mere symbol and decoration. There are several options for the "breaking"of the pitched roof: reconstructing a non-verticalhorizontal-system terrain; recreating the relationship between cognition, body and spatial objects; or def i ning the orientation, movement and intimacy relationship of space. The HWA Cultural Centre answered to the above strategies. Objectively, it extended the architectural research programme of pitched roofs, and explored the modern application rule of pitch roofs.

HWA Cultural Centre reconstructed the site terrain using spirally ascending pitch roofs, integrated single buildings with different heights and volumes depending on their functions under one whole roof,and defined an inward courtyard space with flexible boundaries. Under the tight limitation of the site,the whole group of buildings was designed to form one courtyard. Four single buildings were covered by 4 different single pitched roofs respectively, and the roofs all extended the walls to some extents. Four roofs spirally descended in order, and ended up as the basement rooftop in the courtyard, and became a part of the terrain. The slopes of the roofs also gradually turned flat, with the roof on the east side closest to the height of a body, and welcomed the guests in a friendlier manner. The "crack" between the roofs on the east and north sides also emphasized this entry direction. Under the "crack" is the comfortable entry space that spread far under the roof.

The entire concrete frame and slats are expected to be cast using bamboo pattern formwork. Highperformance bamboo fiber composite (bamboo steel) louvres are used for the walls between columns and the ceilings. The bamboo steel louvres between columns present a regular polyline wave, and form a double enclosure together with the screen wall.The ruggedness of concrete and the softness of bamboo steel are united together by the common bamboo texture. The roofs of the whole building group were built with plain traditional sheathing, to deliberately keep distance from the symbolized tile roofs. Part of the pitched roof on Building No.3 was opened to provide natural sunlight for the rooftop garden it covers. This method is similar as used for the basement light well (small sunken garden). It emphasizes once more the rule of combining pitched roofs and site terrain. (Translated by CHEN Yuxiao)

設計條件

基地：現有的基礎與地下室需要保留和利用；使用：為藝術／服裝的收藏／展示，服裝表演，訂貨，報告／講座，書店，餐飲／咖啡／品酒等提供性質、尺度差異較大的空間。

形式

經過反復組織和簡化，我們決定采用一個連續盤旋上升的單坡頂統一5個體量不同的單體建筑，同時圍合出一個庭院，即賦予復雜的群體一個明確的形式關系。

空間

多種多樣的功能和三度傾斜的屋頂創造了室內空間的豐富性。圍繞院落，深檐提供了一系列半室外空間。天花板構成一個在室內和室外綿延且變化的體系，調節不同空間之間、空間與結構構件之間的關系。

結構+材料

我們利用混凝土框架結構和剪力墻的結合，塑造出質量各異的空間，并在多處也顯現出現澆混凝土。提供遮陽與遮擋的格柵和天花板均以竹鋼為材料。屋面用瓦采取傳統的粘土望磚。整體呈現出一種“土木”的調性。

目前階段

開始施工。已進行5輪混凝土模板試驗，決定采用蓆紋質感。□

Design conditions

Site: The existing foundation and basement need to be retained and utilized in the new design.Program: To provide spaces of different qualities and scales for art/garment collections and displays,fashion shows, procurement fair, workshops/lectures, bookstore, and restaurants/cafe/wine tasting.

Form

After a series of tests and simplifications,we decided to use a continuous spiral of a singlepitched roof to unify five buildings with different volumes while enclosing a courtyard in the center.In other words, a clear formal relationship is given to a complex group.

Space

Rich programs and a three-dimensional tilt of the roof create a great variety of interior spaces.Surrounding the courtyard, deep eaves provide a series of semi-outdoor spaces. The ceilings form a flexible system that stretches from indoors to outdoors, mediating the relationship among different spaces, as well as between spaces and structural components.

Structure + Material

We use a combination of concrete frame system and shear walls to produce spaces of diverse qualities, and reveal cast in-situ concrete in multiple places. Both the grating on the elevations and ceilings that provide shading and screening are made of bamboo fibre reinforced polymer. The roof is clad with Wangzhuan or traditional clay ceiling bricks.Due to the natural appearance of the materials chosen, the entire complex gives an overall feel of"Tu Mu" (earth and wood).

Current phase

Under construction. Five rounds of concrete formwork tests were completed and the woven mat texture was finally chosen.□
