Launched in 2001, based in Tainan (Taiwan)

Launched in 2001 by Kuo-Chang Liu (b. 1972). OU (Open United) Studio exhibited at the 2006 Venice Biennale Architecture Exhibition and acted as exhibition designers for the Taiwan Pavilion at the 2011 Venice Biennale Art Exhibition. They are best known for their 《 Blue Print 》 project, the "renovation" of a one-hundred-year-old building partially demolished for the widening of a road, where a section-perspective drawing of a room interior painted on the severed and exposed wall of the building, from which beams and furniture jut out in relief over the road, evokes memories of the city lost. Works in the same series have been executed in Berlin, at the Hong Kong & Shenzhen Biennale of Urbanism/Architecture and the Museum of Fine Arts, Taichung. Rather than demolishing or restoring a group of warehouses fallen into disrepair and engulfed by trees, for 2003's competition-winning Anping "Tree House", OU Studio wound a steel frame through them vertically and horizontally. These architects expert in renovations with an artistic feel were also responsible for expansion and alteration work on the "JJ-W Hotel", featuring a scattering of house-like rooms.
