CONTEXT
Area: 486,609 m²
Users: Families, Tourists
Land: Industrial, Agricultural
Location: Suzhou-Kunshan, China

Strategy: Canal gates, Clusters & Domes

The first stage of this project consists of alternating canal circulation to allow the chosen cluster zones to purify the incoming polluted water and release of such clean water into the connecting rivers. The second stage of this project consists of cleaning the contaminated canals & rivers of Suzhou, Kunshan and Shanghai by the use of 12 natural water filtration system as seen in Houtan Park by Kongjian Yu. The third stage consists in the creation of 3 distinct continents dome habitats which serve as an educational-tourist attraction spot as in Eden Project by Nicholas Grimshaw.


Stage I: Alternation and Reuse

10 factory sites and 4 rivers play a vast role in the process to circulate clean water to the surrounding canals. Canal gates could be installed as an input and output for the whole strategy to work. The present factories only conserve their frames and each factory use depends on the needs of the local population.

Stage II: Filtration and Renaturalization

Constructed wetlands treat polluted input water by the selected species of plants, while terraces oxygenate the river. 11 of such terraces are 5m high to base level, filter the pollutants and create a pleasant boardwalk. Terraces are made of decomposable bamboo.

Stage III: Habitat Reconnection

Tropical, temperature, continental biomes are made of light steel tubes and joints, cladding panels are made of ETFE. Each biome is a hex-tri-hex space frame. Panels act as a thermal blanket and keep each of biome conditions conducive to housing flora.


Aesthetics

During initial site research on water conditions in the area, considering that the west side ponds and canal front were eroded over time, therefore the strong emphasis was put into agriculture and water preservation. The 3 biomes resemble the organic & fluid shape of the untouched East side stream.

The idea to excavate the water cleaning terrace 5m below the ground came from the Cheonggyecheon public space canal in Seoul, South Korean restoration project. This approach uses less land and showcases the 3 biomes at full extent.
