Stone & Webster, established in 1893 by MIT graduatesCharles StoneandEdwin Webster, was a national leader in electrification and power generation, and provided services in engineering, construction, environmental remediation, infrastructure, and plant operation for industrial clients. After the Boston Redevelopment Authority acquired and demolished sections of South Station for redevelopment, Stone & Webster decided to relocate their offices to this new site. Los Angeles-based architectural firmWelton Becket & Associates, designed the office building in a late International-style, which serves as a counter to the masonry and classically designed, South Station nearby. The steel frame with metal and glass skin and boxy form are effective at delineating the building from its neighbor, but is not pedestrian-friendly at the ground level as the raised ground floor is lined at the sidewalk by concrete steps. The building is now largely leased to Fidelity Investments.
