The invited competition for the masterplan of the 2013 Beijing Horticultural Expo required the planning of an area equivalent to Central Park. In our estimation, to plan for an area of such a scale solely around the requirements of a short term event seemed to be counter intuitive. Instead we proposed to plan the site for different time scales, where the various landscape and infrastructural systems implemented on site, would enable the emergence of different organizations and qualities at different times. Even more significantly, this strategy would allow for transformable public spaces that could be enjoyed by visitors to the expo and subsequently by Beijing locals in their everyday lives. As the site consited of a large abandoned quarry and landfill, significant transformations to the grading was an early given. The team chose to use this as an opporunity to propose strategic manipulations to the ground conditions of the site. New wetlands, rain gardens, infrastructure, architecture and public spaces were woven with the larger scale landscape and ecological ambitions for the region and the revitalization of the Youngding river. These landscape systems were strategically distributed to enable a more intelligent management of the site's drainage and irrigation as well as creating new diverse habitats along the river ecology.
