One of the finalists of Inhabitat’s recent Biodesign competition, Aquaponic Future Housing comprises a three-level home 3D-printed with biodegradable plastic that also has its own closed-loop aquaponics system. “A symbiosis between hydroponics and aquaculture,” aquaponics is a perfect example of a self-sufficient, living machine that produces food without creating waste or pollution. Simply put, an aquaponics system combines aquaculture (the raising of edible fish) and hydroponics (the growing of plants without soil) and consists of a hydroponic grow bed filled with plants positioned above a water tank containing fish or other aquatic life. Fish excrement and uneaten feed is filtered out of the water through the plants’ roots and is absorbed as essential ammonia-rich nutrients that allows plants to thrive. This win-win situation creates a highly productive ecosystem and yields more food per square foot than any other form of agriculture. Read more about aquaponics here.

“The building uses novel structures and fabrication, proposing lightweight bend-active aquaponic towers, which sustain growing crops and fishing,” the designers write in their competition brief. “The towers enclose inhabitation units which are 3D printed using bioplastic created in-house from vegetable starch. This flexible house of the future acts as a Rep-Rap 3D printer using robotic fabrication for both weaving carbon enhanced bioplastic rods as well as extruding bioplastic layers.”
One benefit of this unique housing program, according to the designers, is its ability to regenerate urban brownfield sites that have been marred by various pollutants and make more land available to house a rapidly growing population.
“Similarly to aquaponics,” the designers say, “it enables a cradle-to-cradle lifestyle where fresh organic food and construction materials are produced in-house by the inhabitants.”
