The nine-story, 290,000sf, class-A mixed-use facility will provide state-of-the-art lab space geared toward emerging life science companies.

The building, which will include first floor retail, community art spaces and a four-level underground parking garage, will achieve LEED Gold and WiredScore Platinum certifications, a testament to the sustainable and highly efficient approach.

The first of three life science buildings as part of the Boynton Yards development in Somerville, 101 South Street will offer best-in-class, high-efficiency infrastructure where companies can imagine and grow. The proposed 6.54-acre development will transform the area into a vibrant work-live-play neighborhood. With more than one million sq. ft. of commercial, residential, retail, public green, arts and performance spaces, the project will bring 4,000 permanent jobs to the city of Somerville and help establish it as one of the region’s most prominent life science hubs.


Shawmut Design and Construction, the general contractor, along with architecture firms SGA and Hashim Sarkis Studios, is executing the ground-up building which will match the quality and specifications of other Class-A buildings while providing state-of-the-art lab space, including advanced wet and dry R&D labs and column-free, 35,000sf floor plates for unique and maximum flexibility. The facility will also feature a below grade parking garage for 250 vehicles, indoor bike storage, and a two-story lobby complete with retail space overlooking abundant public green areas and walking paths.

Shawmut has deployed enhanced safety protocols to mitigate the risk of infectious disease spread across all jobsites. Completion is slated for summer 2021.
