One Post Office Square, Boston,USA

The Project

Set on one of downtown Boston’s most beloved parks, CBT’s entrance redesign capitalizes on the opportunity for spectacular views on the ground level. The transformation of this 10,000-square-foot lobby begins with a three-story Pilkington Planar™ glass wall, framing the perimeter of the building. By extending the lobby to the edge of the actual structure, which used to be a covered outdoor passageway, the lobby is enlarged by 50%. This provides a naturally-lit space for visitors and tenants to meet, have corporate functions, or to simply enjoy the serene museum setting and beauty of the adjacent park. It offers sweeping views of the Charles River, Boston Harbor and Boston skyline. The building, which connects to the Langham Hotel, is home to Putnam Investments, Sullivan & Worcester LLP, Acadian Asset Management, Jones Lang LaSalle and Lahive & Cockfield. The leasing agent is Jones Lang LaSalle.
