Sustainable Pine Tree-Shaped Houses

The treehouse you had when you were 8 — the one with the secret stash of Playboys and Big League Chew shreds strewn about — may still hold a nostalgic soft spot in your heart, but it’s just not plausible for actual living. Architect Konrad Wójcik has taken the treehouse concept out of the actual tree and put it right next to them. These sustainable tree-shaped houses could be going up in a forest near you soon, as the futuristic design and environmentally friendly specs have caught the attention of more than a few potential buyers.

With an array of solar panels, a heat pump bringing in energy from the ground, and a bio-digester to recycle human waste, the goal is true sustainability. There’s no cement or steel used on any of the four floors, just a lightweight but strong wooden frame. Four people can chill here with ease, and the plan would be to have all of the houses within walking distance of public transportation. You may or may not get some stares on the bus, though.
