The El Galpón market in Buenos Aires is proof that even the most unlikely of venues can be turned into a sustainable business with a bit of creativity.

Located within an old train warehouse that had fallen into disrepair, El Galpón is a remarkable co-op market that specializes in organic and fair-trade products. According to Inhabitat, however, the remarkable space also serves as a haven for "permaculture workshops, eco-design fairs, yoga classes, a barter, an organic vegetable patch and even a community online radio" all within one "friendly space."
