How much space do you really need to live? For Beijing architect Dai Haifei, the answer is not much. In an attempt to live virtually rent-free, Haifei built himself a mobile egg-shaped abode small enough to fit on the sidewalk.
It stands a meager 6 feet tall and was constructed from bamboo strips, grass seed, wood chippings, and sack bags. With a little help from the sun, the structure will actually start sprouting in the spring.
All in all, the makeshift home cost Haifei only $1,000 to build—including a solar-paneled roof that generates enough power to run a small lamp inside the space.
Not everyone could be comfortable in such tight quarters, but for this innovative architect, it’s home.
