The 157 Berkeley Street project is a 795,000 square foot., 23-story tower with four stories below grade (three parking levels and one service level) that expands Liberty Mutual’s headquarters in Boston.
Project highlights include the underpinning of the adjacent 11 story building, extensive quality control of the Indiana limestone facade, and a first-in-kind glass bridge spanning Stuart Street, which is now considered an architectural highlight in the area, and connects the headquarters to the Liberty Center, a 27,000 square foot, two story above ground conference center designed to support the 157 Berkeley headquarters.The 130,000 square foot 10-story 330 Stuart Street building was also substantially gutted and structurally connected to the tower.
Located in a busy neighborhood, the project was completed during three shifts with minimal interruption to the surrounding area and the restaurant Grill 23, which the tower was built directly on top of while it remained open to the public.
