The new city-office of Utrecht is located on an auspicious but extremely complex site, partly above the new central station concourse and transport hub. The first five levels are devoted to public functions. Level 6 to 11 are rectangular and are linking two divided towers with offices.The structure along the perimeter expresses the stability.
The south tower is build on only 5 possible points of support. Because of the large footprint, the design pursues an ‘urban ecology’ with different floor plans seeking daylight in a variety of ways.The interior design is for a flexible office with activity-based working spaces. Three floors (levels 6, 11 and 21) will serve as meeting places (plazas) and are characterized by higher ceilings.
