2 / 8 site current conditions and original masterplan


Nowadays China is undergoing an unprecedented process of urbanization and millions of people move every year from the countryside to the more developed coastal regions. In order to release the pressure of such migration on the already saturated metropolitan areas, the central government has planned to create as many as twenty new cities every year.

中國正經歷前所未有的城市化進程,每年都有數以萬計的城郊居民涌入更為發達的沿海地區。中央政府已計劃年均增建二十余新城以緩解這股移民熱潮給城市發展帶來的壓力。

大踏步城市化帶來翻天覆地的變化,既是挑戰,也是機遇。一方面,我們不可能為保持傳統的價值而拒絕城市化的進程,不可能完全與資本的邏輯背道而馳;另一方面,我們要認真而客觀的考慮城市化在環境和社會變化中的代價,這些都必須要被納入城市設計決策的方程式中來權衡得失。

3 / 8 current water system and drainage deficiency


This drastic transformation of the territory offers a unique combination of problems and opportunities. Refusing a mediation with the forces that drive the urbanization would be quite a conservative and unproductive form of resistance. The capitalist logic of profit cannot be totally denied, but the social and environmental effects of the urban transformation should be put into the picture and evaluated as part of the overall balance.

通過對城市化成本系統性的分析,這個設計方案旨在探索一種尊重當地原有自然環境和地貌、以生態系統的優化為重要原則、分期化的、彈性設計的策略,同時兼顧經濟可行性,試圖避免全球化市場驅動發展所帶來的地方性喪失。

4 / 8 project development: meshing


Through a systematic analysis of the costs of urbanization, this project aims to demonstrate that a design based on the specificity of the local morphology, the optimization of the natural systems and a resilient phasing strategy can be a viable economic investment while avoiding at the same time the total annihilation of the local identity, so often associated to globalized market-driven developments.

臨港是中國“十一五”規劃中“1966”大上海發展戰略的一部分,位于長江三角洲入海口的農墾區;2020年將有80萬常住人口。
在最初的規劃方案中,鄉村的原始風貌被完全忽視 ------ 當地建筑和自然風貌消失殆盡,原先依運河而建的線性村莊的獨特肌理徹底喪失,取而代之的是單一功能的巨大分區和高度幾何化的千篇一律的空間格局。

5 / 8 project development: urban prototypes


Lingang was planned as part of the 1966 plan for the regional expansion of Shanghai, on an area of reclaimed land on the head of the Yangtze River Delta, with the goal of housing up to 800,000 inhabitants by 2020.

單一區劃和低密肌理嚴重增加了單位面積的城市化成本。機械刻板的幾何化設計缺乏靈活性,城市在全部建成之前絲毫無法運轉,基礎設施則被迫要在開發起初全部建成。
不僅如此,在環境方面,圍海造田會極大影響到當地的水文系統,鹽沼地的生態環境被破壞,排水受阻,也預埋了潮汛期爆發洪水的隱患。

6 / 8 prototypes proliferation


The original masterplan, organized in a very rigid geometrical fashion, does not take into account two important elements of the site: the existence of a consolidated pattern of linear villages along agricultural canals - which are very valuable not only for their architectural and environmental beauty, but also for their strong social identity - and the presence of the sea, with its ecology based on tidal dynamics.

該項目反思原有總規的薄弱之處,試圖提出一個更加靈活開放的城市物質空間系統:展開一個全新的海岸線設計,同時改善濱海生態系統的狀況,并提供更多親水城市空間;試行一個多中心城市的策略,使整個城市能夠面臨未來變化而自我調整,靈活多變。

7 / 8 prototypes proliferation: bird view


By reconsidering all the economic and ecological variables of the original masterplan, our design aims to create a more dynamic system based on a new coastline that reconciles the natural ecologies with the new urban activities and the creation of multifunctional clusters that can more efficiently adjust to the future changes in the growth of the city.

此外,方案中提出的高密度的城市建設將有利于高效利用土地,以此來保留更多原有村莊形態;同時,在解決城市排水問題時也為建設新的城市水系帶來了契機,這個網絡化的運河系統將造就全新城市肌理,成為建構城市公共空間的重要因素。

8 / 8 masterplan phasing


On the one hand, a higher density scheme meets the goals of the original masterplan while allowing the preservation of the existing linear villages, on the other hand, the solution to the insufficient draining capacity of the terrain gives the opportunity to create a new network of canals and water bodies that organize and structure the urban fabric, becoming a crucial element of the public space. Finally, the new design maximizes the coastline and creates a multifunctional water interface, generating a higher land value that can at least partially compensate the costs of the dredging and earthwork needed, making the project economically sound.

新的方案不僅最大程度地利用了自然海岸線,創造了多種親水的城市界面和功能空間,其帶來的地價提升更可補償建設排水系統等土方工程的經濟投入,使整個方案更具經濟可行性。
