Dai Haifei, 24, from China's Hunan province, looks out from his egg-shaped mobile home where he has been living for the last two months.
Haifei has parked his unique home near his office in Beijing.
The house cost about $1,000 to build, and is made of bamboo strips and mattress, topped by a layer of water-proof material.
It has bags stuffed with processed wood chips and grass seeds that could grow grass when spring comes, covering the house like a quilt.
No mention if Mr. Haifei has plans to eradicate the bugs and worms that will be attracted to the grass.
