CLIENT:
City of Tongzhou, China
DESCRIPTION:
The ancient river port city of Tongzhou originally supplied Beijing with food and imports. Typical of many ancient cities, Tongzhou was a walled city and in the 1960's most of the wall was removed.
Unprecedented building development prior to the Beijing Olympics challenged our team to consider the environmental consequences of the park's surrounding apartment and office buildings.
This proposed design for Xihaizi Park introduces phytoremediation and greywater treatment strategies to this densely populated city. L+A worked within the traditional bounds of Chinese landscape symbolism by re-imagining a new "wall" or datum which defines spaces within the park below and viewing from above. The "wall" is permeable and changes along it's route from solid built structures, for cafes and recreation, to transparent overlooks. A bridge connects a new center island to either side of the canal.
In this semi- arid area of the world where population puts extraordinary demands on natural resources, it is imperative to employ meaningful and multiple supportive systems. As Betsy says, "Water is the foundation of life, water must be the foundation of planning and design." The water system begins with a large reflecting pool at the base of the existing pagoda. This water is treated through phytoremediation at it's source, then "polished" or aerated over rocks as it flows downstream to the lower pond. Treated, clean water overflow is released back into the canal.
Tanya Kelley worked with the Tsinghua student team to develop the Schematic Master Plan for this project.
