400 Summer Street is a 16-story, purpose-built life science building located in the center of Boston’s Seaport District submarket. Once completed, the 635,000 square foot property will serve as the headquarters of Foundation Medicine, a leading Boston-based biotechnology company and subsidiary of Roche Pharmaceuticals, which has leased 100% of the laboratory and office space in the building. 400 Summer Street is part of the 33-acre Boston Seaport development project led by WS Development and will feature both interior and exterior public spaces connecting Summer and Congress Streets, as well as more than 30,000 square feet of neighborhood retail space. The building was designed by Morris Adjmi of New York and is being constructed by Suffolk Construction of Boston.

Robust funding for research and development has continued to fuel growth in the life science sector, with worldwide total Pharmaceutical R&D spend expected to eclipse $200 billion through 2021.¹ “We have a strong conviction in life sciences real estate and believe there will be lasting demand for high-quality lab and work space in the world’s top innovation centers. We are thrilled to be growing our portfolio of trophy life science assets with our investment in 400 Summer Street in Boston’s Seaport. In addition to our recent acquisition in San Francisco’s Mission Bay, we are now serving the two largest and most premier life science clusters in the U.S.,” said Justin Pattner, KKR Partner and Head of Real Estate Equity in the Americas.
