The new Cultural center Sentralen occupies Christiania Sparebank's old bank building (1899) and the adjacent office building (1900) which was acquired by the Sparebank Foundation in 2007. In2012 Atelier Oslo and KIMA won an open architectural competition with a proposal suggesting a work process and the description of it, without any drawings. The work process envisioned the design of a new cultural center, and the implementation of such a reconstruction. The plan layout and content of the project at this point was completely open.
