CBT designed this new 22-story, 855,000-square-foot commercial office building with 574,800 square feet of office to be an integral part of Liberty Mutual’s Headquarters campus. The building’s distinctive triangular massing and curved edges are a direct response to the site configuration and resolution of the diagonal street grid. The punched window façade is articulated in a distinct tripartite massing with a significant base, middle and top that relates to the surrounding buildings. The length of the building is also broken down by articulating the massing vertically.
Clad completely in Indiana limestone with subtle details at the window line and crown, the design exudes a quiet elegance and strength. The exterior architecture is highly contextual, blending seamlessly with Liberty Mutual’s existing buildings and with the traditional architecture of the surrounding area.
The program includes commercial office space, an employee Cafeteria that spans the ground level and second floor, an urban park and four levels of below-grade parking. An all-glass luminescent pedestrian bridge connects the new building at the new 700-person cafeteria level with a new 25,500 square foot conference center in the headquarters building and links the complex together over street level. The project also integrates an existing 104,750 square foot historic building on the site -- Salada Tea Company’s original U.S. headquarters built in 1917 – into the complex, preserving a city landmark.
