In an attempt to create a more sustainable domicile, some homeowners use energy-efficient light bulbs, swap out normal showerheads for low-flow ones, or put on a sweater so they can turn down the thermostat. However, others are taking sustainability—and their homes—to the next level. These ten innovative designs move the owner off the grid, into the trees, and toward a more environmentally-sound future.
Earthbag House

Sandbags protect houses from floods, but aren’t normally considered building material. However, Kelly Hart, a constructor who runs the Web site GreenHomebuilding.com, built this house out of misprinted rice bags filled natural material (earthbags). The outside layer is papercrete, recycled paper mixed with small amounts of cement. The earth bags provide insulation, weatherproofing, and are easy to construct. According to his Web site, the house requires minimal use of wood, concrete, and steel for construction, and many recycled materials were used. The heating is primarily solar—air tubes provide cooling and food is grown in a central greenhouse.
Build Local, Build Green

My friends Becky and Grant spent nearly two years building this house, located in Northern California. Their overall approach has been to build small, build natural, and use as much reclaimed and local materials as possible. To this end, they’ve succeeded.
Ninety percent of the exterior walls are made from straw bale; the downstairs exterior walls are covered with earth and lime plaster. The interior walls are plastered with clay gathered from their land, resulting in a beautiful, neutral-toned finish with a velvety texture. The cedar siding was milled onsite, using diseased trees from their property. The redwood deck, interior doors, and cabinetry in the kitchen use local reclaimed or restored wood. Insulation is from recycled denim and strategic placement of windows ensures natural cooling. They also have a solar hot water heater, a bountiful veggie garden, fruit trees, clucking chickens, and, as if the industriousness never ends, a baby on the way. Sustainability for generations to come!
Modular Earthship

I’m not sure if I’m ready for a hemp Earthship, but luckily I have options. They come in packaged, modular, hybrid, and custom; the above is an example of a modular Earthship. With water catchment from the roof, reuse of greywater, solar panels, and composting toilets, I could definitely tune in with nature, turn off the TV, and drop off the grid.
Project BioDome

Edward Dilley, creator of Project Biodome, has a vision: pull drinking water from the air, gather heat and electricity from the sun, and live completely supplied for in his geodesic sustainable dome. Somewhere in the mountain near Elko, Nevada, he seems to be doing just that. According to his Web site, you can order a kit and construct one yourself. Might want to look into local building codes first.
Tree House

If you aren’t afraid of heights, the 02 Sustainability Tree House could serve as your next home away from home. It is made from small amounts of eco-friendly resources and is hung by cables rather than bolted into trees, as to not disturb your structural helpers.
