Arkan Zeytinoglu calls his projects 'built theory.' Since many years, he has dealt with 'the geometry of light', which describes best his special approach to architecture. But as an architect, Zeytinoglu, who studied at University of Technology TU Graz under Günther Domenig and later on at Cooper Union in New York, devotes himself mainly to building activities. Since his offices foundation in 1995, realizations have included works in the field of hotels and resorts, gastronomy, and luxury residences. In May 2010, the internationally much-noticed Austrian pavilion at Expo 2010 Shanghai (ARGE SPAN & Zeytinoglu) was inaugurated. The book contains all essential realizations as well as a work list and an outlook at the buildings to be completed soon.
