Park Tower at Transbay

San Francisco, California

The 29,000-square-foot site for the Park Tower at Transbay is located at the corner of Howard and Beale streets in the Transbay district, near San Francisco Bay and across the street from the new Transbay Transit Center. The 605-foot-tall Park Tower will be 45 stories and include 750,000 square feet of commercial office space. The tower is designed as a series of three massings that offer a variety of floor plate sizes for tenants. Within these distinct massing elements, the design carves out a series of large outdoor terraces that provide substantial outdoor amenity space to office tenants.

The tower’s façade is composed of floor-to-ceiling glass and is articulated with a series of vertical glass fins that relate to the location of the tower terraces, which occur at a three-story module. The podium façade also utilizes a series of vertical double fins in addition to a module of fritted glass. The fritted glass element is repeated through to the base of the building to help continue the tower articulation and materiality throughout the three tower massings. 

At the base of the tower is a covered 3,600-square-foot outdoor plaza with a 35-foot-high ceiling. The area is designated as privately owned public outdoor space (POPOS) that abuts both the tower’s main lobby and adjoining retail space. Along with a series of outdoor seating areas, a major focal point of this outdoor space will be a large site-specific artist installation, which will be integrated into the main wall of the tower’s core.
