Construction Cost: $53,000,000
Client Need:
EMC expanded their downtown Des Moines location by adding this corporate high-rise adjacent to their existing headquarters building. They sought to achieve a bold and sophisticated image through the building design.
BBS Approach:
The sculptural expression was developed to take advantage of the building’s location within the skyline. Viewed from the west, the angled roof acts to counter the gradual decline of heights from north to south along the downtown skyline. Viewed from the south, the higher tower face establishes a strong figural identity for the EMC complex.
