“They say it takes a village to raise a child, but in this case, 20 children are hoping to raise a village,” reports Good News Network.

Twenty teens and 10 adult volunteers have raised nearly $40,000 to build an eco-village they call “The Impossible City” for a homeless encampment in Seattle. The teens are working through Sawhorse Revolution, a non-profit carpentry program for high school students guided by professionals in architecture, engineering, and construction. The dollars raised through their campaign on Indiegogo will help build secure, personal shelters, composting toilets, and a community kitchen with solar-powered lighting and hot water.

The campaign has raised over $39,000 of their $42,905 goal so far, but for every $5,350 they raise above the previous goal, they’ll build another structure. Watch the video on Good News Network, then head on over to Indiegogo to see how you can help.
