Feasibility study for the empty site next to the new National Museum in city centre of Oslo. The client wanted to assess the possibilities within the current zoning plan and explore the potential in this, before embarking on a long, new zoning process. The current zoning plan is the last remains of the abandoned proposal for the Deichman Library at Vestbanen by OMA/Rem Koolhaas and Space Group; and its characteristic snake shaped plan seems oddly out of place with the new National Museum just completed next door. The study looks at various arguments to keep certain intentions in the existing plan, while optimizing the volume for a new formal condition, thus reducing the need to re-zone the area. Following the study, the client decided to start a process of re-zoning based on a new competition proposal by Oslo Works and HZA.
