用敞廊圍合的小廣場 

A Small Plaza Enclosed with Galleries

永嘉路位于上海老城核心區，周邊分布著眾多老住宅區，街道尺度宜人，綠樹濃密，沿街多為生活配套小商業，生活氛圍濃郁。309弄口袋公園的基地位于永嘉路中段，借老城區風貌整治的契機，區政府部門決定拆除原用地內存在消防隱患的兩排殘舊住宅，將其改造為服務于周邊居民的城市公共空間。基地周邊除了街道，缺乏屬于居民使用的公共場所，因此設計一個尺度宜人、可供日常使用的公共空間對于這里是一件好事。

^{Yongjia Road is located in a historical downtown district in Shanghai, with many old residential blocks scattered in its neighborhood. This road is of pleasant scale and luxurious greenery, crowded with small retails. One can sense a strong living atmosphere here. The Pocket Plaza in lane 309 sits in the middle of Yongjia Road. Taking the opportunity of old quarter renovation, Xuhui District Government decided to dismantle two rows of shabby residences with fire hazards and transform the site into a public urban space. Based on observation, we believe that an open plaza with appropriate scale would be most necessary and suitable for this neighborhood.}

拆除老建筑后的用地大致呈長方形，沿街寬約18米，縱深約40米，與街道幾乎垂直，東南西三面均被住宅圍合，空間呈口袋狀。公共空間被設計為由敞廊圍合的小廣場，通過地坪抬高0.5米增強場所感，同時與街道之間形成有趣的抬高視線關系。廣場區域設置旱噴，根據不同時段選擇開啟或關閉，軟性控制廣場的使用方式。廣場南側盡端布置兩個隱蔽的輔助用房，與廣場之間用一道連續曲折的耐候鋼板墻隔開，鋼板墻成為廣場盡端的邊界。

^{After demolishing those old buildings, the site turned out to be a rectangular area, 18 meters in width and 40 meters in depth, almost at a right angle with the street. It is enclosed on three sides (the east, south and west sides), shaped like a pocket. We created here a small square fully enclosed with open galleries. The ground of the square is 0.5m higher than Yongjia road, providing a sense of territory and an interestingly elevated view of the cityscape. Inside the square, a dry fountain can be switched on or off on required conditions, which serves as a soft management strategy to control the usage. The south end stands two secluded auxiliary rooms of continuous folded surface, separating from the square as a notable boundary, covered with weathering steel wall.}

廣場開放面通過緩坡與街道連接，緊貼人行道為標志墻與低矮的灌木花池，東北角設置便于管理的鐵移門，移門與灌木高度控制在1.2米高，保證視線貫通。廣場東西面緊貼的均為住宅山墻，東面山墻按原樣重新粉刷，西面山墻在重新粉刷之余還特地保留了一段老墻的原有肌理，隔著敞廊后面的竹叢若隱若現。

^{The entrance connects to the street with a gentle slope, defined with a logo wall and a framed flower bed with low shrub beside the sidewalk. An iron sliding gate was installed at the northeastern corner to achieve better management. The iron-gate and the shrubs keep the height at about 1.2 meters as a boundary for the plaza. The residential pediments of both the east and west sides were repainted in its original appearance, for the west side, the old surface texture was also preserved. They are partially hidden behind the bamboo grove planting along the open galleries.}

鋼木結構與紅面磚 

Timber-steel Structure and Red Tiles

敞廊是主要的構筑物，四段長廊呈風車狀，圍合出規整的長方形內院，廊下高度刻意壓低至2.1~2.7米，形成親切的尺度，同時整體與周邊建筑在高度上形成合適的比例。敞廊形式上采用精致的鋼木混合結構，考慮到居民公共空間的屬性，在理性的形式基礎上特意增加了具有戲劇性的、富有張力的細節。每個典型的鋼木梁架單元均由鋼柱、木梁、鋼拉桿組成。鋼柱由兩片扁鋼組成，主木梁由成束的疊退木方組成，向中心廣場出挑承托輕盈的金屬屋面。木梁加載于鋼柱上，屋面的重量由梁傳給鋼柱，梁后端的鋼拉桿用于平衡前端出挑的重力。木梁與鋼柱的連接節點被設計為可拆卸裝配節點，這個節點專門設計為單向轉動模式，反向限制梁的轉動，用以平衡風對于屋面的上掀力。

Four galleries with a basic beam frame formed a windmill shape, enclosing the rectangular plaza. The ceiling of the open galleries is intentionally lowered to 2.1m-2.7m, a friendly height harmonious with neighboring buildings. The open gallery adopted a timber-steel structure. Based on its rational architectural form, we added dramatic details to build public attention. Each typical unit of the timber-steel beam frame is composed of steel pillar, wooden beam and steel cable. The steel pillars consist of two pieces of flat steel. The wooden beams are multi-layered. Their cantilevered parts are used to bear the light metal roofing. The weight of the building is transferred from the wooden beams to the steel pillars. The end of the beams is fixed with steel cables in order to keep its balance. All joints are assemblage ones. These joints are rotatable only in one direction, so that they can restrain the rotation of beams and counteract the wind force pushing roof upwards.

周邊住宅區多以上海城區常見的暖色調涂料或清水磚為主，因此廣場地面鋪磚選擇了最常見的紅色透水磚，木梁、屋面底部及坐凳采用淺色原木，耐候鋼板墻則是銹紅色。整體暖調的氛圍里，鋼柱則采用了明亮的鮮艷綠色氟碳噴涂，反差色也帶來了輕松的日常氣質。

^{The residence in the neighborhood is mainly painted with warm-toned color or built with ganged bricks, which are very common in Shanghai’s urban area. Therefore, the plaza ground was paved with common red water permeable brick; its wooden beams, soffit and benches are made of light color logs and the weathering steel wall is painted rust red. In this warm-toned context, the steel pillars were painted into astonishing bright green by fluorocarbon spraying. Such a sharp color contrast has brought a kind of everyday relaxing atmosphere.}
