Description
Now fully permitted, 300 Mass Ave is moving into the construction phase, with completion and occupancy anticipated in early 2016. The research and office portions of the building – all but 15,000 square feet that has been designated for retail uses – will be occupied by Millennium/Takeda, a life science company that is currently in University Park at MIT and will be expanding its footprint to support a more extensive research program. Retail shops and restaurants will occupy nearly the entire frontage of the building along Massachusetts Avenue, and will be identified when construction of the project is further along.
