Developers have teamed up with environmentalists to turn Calhan's massive tire pile into the world's largest development of earthships.
Earthships are an eco-friendly form of home building that use dirt-packed tires to form highly insulated walls.
The development, to be called Tiregate East, will also be the first development to include tire-made townhouses, condos and duplexes, as well as the world's first high-rise earthship shopping and convention complex.
"It's a win-win situation," said Nolan Shiner, a partner in the project. "We have more than enough tires on site to build a small city and plenty of land. I can't wait to get down there and start packing tires."
Because earthships are heated only by the sun, and powered by solar cells, the massive new subdivision will be entirely off the grid, developers say.
The gated subdivision will have a tire-related theme, with tire-made fences around the development, and roads made mostly from shredded tires.
