[6] The primary building of the development is the 43-story office tower, which will feature a three-story lobby and high-end amenities.

[9] In January 2019, State Street Corporation was announced to be the anchor tenant in the new building,[10] and in September 2023 they began operations from the location as their new global headquarters.

This change was announced in July 2017 when the developer decided to convert 118 apartments into 55 condos due to a slowing demand for luxury housing in Boston.

[3] The residential tower will contain a fitness center, swimming pool, rooftop garden, clubroom, private kitchen and diner, yoga room, golf simulator, pet spa, concierge services and a sky lounge and terrace.

The building is intended to house a flagship store, and will include an entrance to the Haymarket Square subway station.

The garage was constructed in the 1960s as part of the Government Center urban renewal project; it contains 2,300 parking spaces.

Due to the fact that the garage is entirely made out of concrete, it is considered to be an eyesore by many, along with the nearby City Hall building.
