Kendall Square Building B Laboratory provides over 200,000 square feet of private industry biotechnology research laboratory and office space on six levels, 8,000 square feet of retail space on the first level, and a six-level underground parking facility. Part of a mixed-use, life sciences development, it is one of three buildings forming the facades of a new public square created in this recently developed part of Cambridge adjacent to MIT. The design extends the vibrant Cambridge street life into the building via a gently sloped monumental stairway that rises within its six-story atrium. The plan accommodates a full range of laboratory spaces, lab support spaces and offices. It is LEED Gold certified for core and shell construction.
