Grey- and rain-water is used to grow food in close proximity to the urban consumer. Spin-offs become resources: gas and biomass for energy production in addition compost and clean water. To establish the necessary framework for the transposed use, the crude existing structure hosts bamboo construction, exploring its limits in multi-floor commercial application.Download project entry poster (PDF, 1.99 MB) »
