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，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。

拆除老建筑后的用地大致呈長方形，東南西3 面均被住宅圍合，空間呈口袋狀。公共空間設計為由敞廊圍合的小廣場，抬高地坪增強場所感，與街道之間形成有趣的抬高視線關系。廣場區域設置旱噴，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，鋼板墻成為邊界。

敞廊是主要的構筑物，4 段呈風車狀，圍合出規整的長方形內院，廊下高度刻意壓低至2.1～2.7m，尺度親切，整體與周邊建筑高度上形成合適的比例。敞廊采用精致的鋼木混合結構，特意增加了具有戲劇性的、富有張力的細節。

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。在整體暖調的氛圍里，鋼柱則采用了明亮的鮮綠色氟碳噴涂，反差色也帶來了輕松的日常氣質。

評委評語

這是一個以設計來詮釋當下城市更新背景下，傳統街區風貌保護與市民日常生活緊密相關的作品。設計者在因消防安全要求拆除而留下的空地上以非常節制的設計手法將其演化為具有建筑學意義的“留白”場所，以期容納下周邊居民戶外生活的各種形式，成為了充滿著濃郁生活氣息和活力的公共生活廣場。我們在退居場地周邊的敞廊內，從鋼與木的精巧建構方式、場地設計上的細微變化等各個維度均能充分感受到生活對建筑設計的意義，也體驗到了設計者的匠心和建筑本身的簡練之美。

Yongjia Road is located in a historical downtown district in Shanghai,with many old residential blocks scattered in its neighbourhood.This road is of pleasant scale and lush greenery,crowded with small retail shops.One can sense a strong atmosphere of lifestyle 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.

After demolishing those old buildings,the site turned out to be a rectangular area,18 m in width and 40 m in depth,almost at a right angle with the street.It is enclosed on three sides (the east,south and west) and shaped like a pocket.We created here a small square fully enclosed with open galleries.The ground level of the square is 0.5 m 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 depending on the conditions as a soft management strategy to control the way the square is used.The south end has two concealed auxiliary rooms separated from the square by a continuous folded weathering steel wall,forming a notable boundary.

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 2.1～2.7 m,a friendly height harmonious with the neighbouring buildings.The open gallery adopted a timbersteel structure.Based on its rational architecturalform,dramatic details were added to attract public attention.

5 草圖 Sketch

The residence in the neighbourhood is mainly painted with warm-toned colour or built with bricks,which are very common in Shanghai's urban area.Therefore,the plaza floor is paved with common red permeable tiles;the wooden beams,soffit and benches are made from light coloured logs,and the weathering steel wall is painted rusty red.In this warm-toned context,the steel columns are sprayed with a bright,vibrant green fluorocarbon paint.Such a sharp colour contrast has brought a relaxing everyday atmosphere.

Jury Statement

This is a design that illustrates the close relationship between the traditional street and the daily life of citizens against the current background of urban renewal.The designer has developed an architecturally significant "blank space" in a vacant area that was left over due to fire safety protection with very modest design techniques,in order to accommodate the various forms of outdoor life of the surrounding residents.It has become a public life plaza full of vitality,providing a rich living atmosphere.In the open corridor around the retreating site,we can easily see the significance of life to architectural design from various dimensions such as the exquisite construction of steel and wood and the subtle changes in site design,as well as the ingenuity of the designer and the concise beauty of architecture.□ (Translated by Dandan Wang)
