Applying the principles of Permaculture, PhillyEarth students worked hard to build this Earthship-inspired greenhouse/chicken coop. The entire structure has been constructed using materials indigenous to the urban environment. This includes materials like worn-out tires, concrete fill, bottles and cans, and shredded paper-based cob. These materials constitute 80% of the total materials used. Of that 80%, all of it was salvaged/found and all free!Photo1 photo23 Photo21 Photo20 Photo19 Photo18 Photo18 (640x478) Photo17 Photo16 Photo15 Photo14 Photo13 Photo12 Photo11 Photo10 Photo9 Photo8 Photo7 Photo6 Photo5 Photo4 Photo3 Photo2
