The Vertical Cities Asia competition brief asked for a proposal in which 100 000 people could live, work and play within a 1 km2 plot in the south of Chengdu. The agriculture and food problem is particularly relevant to the Chengdu region, since this region is responsible for a large share of China’s rice supply throughout history.
With the focus on food security, the intention of this proposal is to preserve the existing arable land and revise the current food supply chain, but at the same time to accommodate the influx of rural migrants - one of the greatest causes for Chengdu’s population growth.
In order to achieve a true vertical town, circulation should take place on all (elevated) levels. Daily activities and needs are all accommodated within the vertical town, detached from the ground floor.
A 40x40x40m cube appears to be a suitable module to build up this vertical town. The 40x40x40 measurement is generic enough to suit a wide range of program, since the floor plan layout is flexible enough to fulfil different program requirements. The cubes are stacked in such a way to create maximum surfaces for urban farming. This can contribute to the reduction of transportation. In turn, this means less air pollution and less fossil fuel consumption. Hence, sustainability is achieved by the prevention of existing problems, rather than resolving the consequences after the problem has occurred.
