Complex

One Dalton Street was built along with a 26-story building, 30 Dalton Street. Pritzker Realty Group is developing the smaller tower.^[4] Both projects are designed by collaborating architects Cambridge Seven Associates and Pei Cobb Freed & Partners, the latter which also designed Boston's landmark John Hancock Tower in 1976.

The building contains a ballroom, meeting rooms available for reservation, a gym with a spa, a private dining space, and other services. There will also be a five-thousand-square-foot (460 m²) park outside the building. The residences have gas indoor fireplaces in each unit, outdoor fireplaces on the balconies of select units, and 11-foot cove ceilings.^[2]

The 160 condominium residences were criticized for being an ultra-luxury property which would have non-resident often hidden foreign owners.^[5] There was considerable controversy for expanding natural gas infrastructure including a new natural gas main at a time when the city was starting to decarbonize. The financing of the construction of the new gas line was also criticized as being inequitable such that in 2018, the Attorney General Maura Healey opposed the Special Contract between National Grid and the developer which had to be approved by the state Department of Public Utilities.^[6][7]
