About One Charlestown

55 Bunker Hill Street, Charlestown, Boston, MA


Proposed $1 billion, 3.3 million square foot redevelopment of the existing 27.6-acre, 1,100-unit Bunker Hill public housing project into 3,200 mixed-income residential units with a neighborhood retail component. All 42 existing Bunker Hill housing buildings, dating to 1941, would be demolished and replaced with new buildings consisting of apartment and duplex unit formats. Visit for more information.


The existing 1,100 public housing units would be replaced with 1,100 new affordable housing units, and an additional 2,100 market-rate and workforce housing units would be constructed for a total of 3,200 units. 

One Charlestown housing units would include 750 affordable rentals, 350 senior affordable rentals, 1,500 market rate rentals and 600 market rate ownership condominiums ranging from studios to four-bedrooms. 

One Charlestown project site would be subdivided into 13 blocks of well-lit, tree-lined city streets that would be fully integrated into the Charlestown neighborhood. The project’s Urban Designer and Lead Architect is Stantec.


Buildings at One Charlestown would range from six to 21 stories tall and would contain a mix of affordable, workforce and market-rate residential units with ground-floor retail. All units would be held to the same high standard.

 Front doors, steps and porches would open to new neighborhood streets; higher buildings would be set back towards existing taller features such as the Tobin Bridge. A new line of connection would be created along Bunker Hill Street with active storefronts, landscaping and a restored street grid. 

Two new neighborhood parks would be constructed as part of One Charlestown, and surface parking would be replaced with underground garages capped with landscaped roofs and courtyards; a total of 2,400 parking spaces would be constructed at One Charlestown including 2,080 off-street and 320 on-street.
