The thin profile of this new headquarters for Cummins’ Global Distribution Business unit preserves open space for a new urban park and reinforces the “street wall” of a major downtown thoroughfare. A highly calibrated façade, with integrated fins and shades, minimizes heat gain and glare and maximizes transparency and access to urban views. A series of double height social hubs—each with a signature staircase—create spaces for collaborative work and chance encounters. The narrow floor plates allow the interior to be entirely day-lit. The sculpted tower, with its inflections and projections, adds a striking landmark to the city.
