With oncology spinoff done, bluebird bio moves to new digs better suited to its future

With many of its employees working from home and others having left for a new spinoff venture, Massachusetts-based bluebird bio decided it was time for a headquarters more suited to its future.

A move from Kendall Square in Cambridge three miles north to Assembly Row along the Mystic River in Somerville will not only suit the changing needs of the company, it will save bluebird $120 million in overhead during the next six years, the company said.
