I don’t know why you would ever want to live in the toilet, but Sim Jae-Duck apparently thought it was a good idea. The late mayor of Suwon, South Korea, Sim, who was apparently born in a restroom, built this toilet-shaped two-story home to celebrate the 2007 inaugural meeting of the World Toilet Association. The association works to help provide clean, efficient and working sanitation system for more than 2 billion living without toilets. The house is 4,520 sq ft, with a large roof-top balcony that is accessible from a staircase that arises from the “toilet-drain” and has a glass-walled bathroom where the windows can be turned opaque for the occupants’ privacy.
