Some Sevit

Sebitseom () in Korean, is officially known as Some Sevit and sometimes known as the Sebit islets , are artificial islands in the Han River in Seoul, South Korea. It is the world's first floating structure built on a buoy that can stay afloat on water. It was built at the suggestion of Kim Eun-sung (citizen of Seoul) in 2006. Seoul made this island by Build-Transfer-Operate (BTO). It has 3 islands: Gavit (), Chavit (), and Solvit (). Yevit is part of Sebitseom, but is not an island itself, but rather, it's an on-land multimedia art gallery complementing the three floating islands.

==Background== Sebitseom, covering a combined area of 10,421 m2 (Gavit: 4,881 m2, Chavit: 3,477 m2, Solvit: 1,271 m2, Yevit: 792 m2), was set to open as a private equity consortium in September 2011 containing convention halls and performance and display areas, along with commercial areas (e.g. restaurant, cafés, etc.), but due to managerial conflicts, the plan was indefinitely postponed. In September 2009, however, roughly $86 million (USD) were invested into Sebitseom (then-named Flo Some or 플로섬) to build the lobbies, decks, and rooftops of each island. As of May 2011, 47% of Some Sevit is owned by Hyosung Group; 10% is owned by Jinheung Company, an affiliate of Hyosung Group; and 29% is owned by SH Construction. Some Sevit has been managed and operated by a manufacturing firm named CR101. Monthly expenses on upkeep and rentals reach around $970,000 (USD) or an annual expense of roughly $11.6 million. The projected expenses is estimated to be over $268 million (unadjusted for inflation) during the next 25 years.
