Overview

One North Wacker is a modern office skyscraper rising 50 stories and approximately 199 metres (653 feet). Located on the west bank of the Chicago River, the tower was completed in spring 2002 after construction began in 1999. It was long known as UBS Tower while that financial firm occupied prime space, and it remains a notable component of the downtown skyline and commercial office market.

Design and structure

The building is a typical late-20th-century/early-21st-century commercial tower with a glass-and-metal curtain wall and a rectilinear silhouette. The design emphasizes efficient, column-free floor plates for flexible office planning and views over the river and the surrounding Loop. Ground-level features include a landscaped plaza and a double-height lobby intended to serve tenants and visitors. Architects and engineers planned the structure to meet contemporary safety, mechanical and circulation standards for high-rise offices.

Location and context

One North Wacker sits on a key site along North Wacker Drive, adjacent to important commuter routes and riverfront walkways. The address, One North Wacker Drive, places the tower in the heart of the Loop business district, within walking distance of transit, dining and cultural institutions. The building contributes to the cluster of high-rise offices that define central Chicago and plays a role in riverfront redevelopment and pedestrian connectivity in downtown Illinois.

Use and tenants

The tower is primarily used for commercial office space. Over its history it has hosted financial firms, professional services companies and corporate headquarters functions. Typical amenities for comparable downtown office towers—lobby services, meeting rooms, parking access and street-level retail—support tenant operations and public access. Leasing patterns reflect demand for centrally located, well-served office floors with river and city views.
