The Austrian Mission to the United Nations is a 12,000 SF space containing the main office of the Austrian Ambassador to the UN and the staff members. The project is on the 31st floor of a 1971 glass curtain-wall tower designed by Emery Roth & Sons. The rigorously defined program, mandated by the Austrian government, included that each employee have a separate enclosed office space with windows to the exterior. The architectural solution was to create a central core containing the support facilities of a conference room, archive, pantry, administration and storage area, surrounded by a circulating corridor whose outer perimeter wall is designed of glass with calculated views through the office spaces to the cityscape beyond.
