CBT designed this 590,000-square-foot commercial office building to be an integral part of Liberty Mutual’s Headquarters campus. The new building seamlessly integrates into the existing urban complex and includes commercial office space and a ground-level and second floor employee café as well as four levels of below-grade parking. A new glass connector bridge connects the current headquarters with the café and unify the entire campus.
The exterior architecture is highly contextual to blend with Liberty Mutual’s current buildings and with the traditional architecture of the surrounding area. The building is designed to achieve LEED Silver certification and is 20 percent more energy efficient than a typical large modern office building.
