Tallest house shaped like a toilet

This giant 7.5-m-high (24-ft 7.27-in) toilet-shaped house was built as the home of Sim Jae-Duck, former mayor of Suwon, South Korea, chairman of a World Toilet Association conference, and aka "Mr Toilet". The 500 m² (5,381 ft² 133.92 in²) floor area contains four high-tech toilets, including one surrounded by glass that turns opaque and produces a mist to make the user feel more relaxed. Residents reach the roof balcony around the "rim" of the bowl via stairs in what would be the "drain" of the toilet. The house’s name, "Haewoojae", means "a place of sanctuary where one can solve one’s worries". Designed by Ko Kiwoong, the house was constructed in 2007 on the same site where Sim Jae-Duck had lived for over 30 years, and 68 years after he had reportedly been born in his impoverished grandmother's outhouse. After Sim’s death in 2009, the house was donated by his family, and is now used as a museum.

Constructed in 2007, Sim Jae-Duck’s aim was to raise awareness that billions of people in the world today do not have easy access to toilet facilities in their homes: "My dream is for the whole world to work together to allow everyone to enjoy sanitary, cultural and environment-friendly toilets. I want no one to suffer from the absence of toilet facilities. It is, after all, a basic human right to have access to clean toilets, however basic these may be. We are trying to make a statement via the Toilet House, that it's about time to break the taboo about toilets and that it's time that we talk about this problem facing 2.6 billion people around the world”
