Verizon-anchored office tower at The Hub On Causeway tops off

The development team behind the 1.5 million-square-foot mixed-use project on and around TD Garden have topped off its last structural component: a 31-story office tower that Verizon is set to anchor when the building opens in 2021.

Delaware North—TD Garden’s owner and operator—joined Boston Properties and John Moriarty & Associates in formally marking the topping-off in the fast-changing West End a few days before Christmas.

The tower at 100 Causeway Street also includes space for software firm Rapid7. But Verizon will take the vast bulk of the building’s 627,000 square feet. The Manhattan-based telecommunications giant announced in July 2018 it was leasing 440,000 square feet for 20 years. It’s unclear which Verizon operations will be based out of 100 Causeway.

As for the larger Hub On Causeway project itself, it includes myriad moving parts: a Star Market, a 15-screen ArcLight cinema, a 1,500-seat concert venue, a 272-room hotel, and a 38-story apartment tower with some 440 (very popular) units. At the same time, there has been a major overhaul and expansion of TD Garden itself.

The first two phases of The Hub On Causeway opened earlier this year. The office tower’s 2021 opening will constitute the third and final phase. Stay tuned.
