Monday night, the public got the first glimpse of a possible future for the parking lot behind CVS, the Armenian Museum of America and other businesses in Watertown Square, and it may include a multi-story garage built by the City and a residential building constructed by a private developer. City Manager George Proakis spoke to a packed room at the Watertown Free Public Library. He discussed a variety of topics, including how the Watertown Square planning got to Monday’s meeting, designing the new look intersection, and the main event: the Demonstration Project that would be built on the Municipal Parking Lot. Due to constraints, such as the City of Cambridge’s water supply line that runs under the parking lot, Proakis said the likely layout would be to put the garage on the area in back of the Armenian Museum of America.

More than a year after the zoning for Watertown Square was approved, City officials are preparing to begin the creation of two detailed plans to revitalize the Watertown Square commercial area, and to redesign the intersection. The project includes changes gto the roadway and intersection, as well as building on the parking lots in the Square. Discussions about the future of Watertown’s major intersection began in November 2023 with the multi-day design charrette, and continued through 2024 with the approval of the new zoning in July 2024, known as the Watertown Square Area Plan (click here to see the approved plan). During 2025, the work has been internal within the City’s Department of Community Development and Planning, in conjuction with consultants, to come up with a Revitalization Plan and designs for the new intersection in the Square, according to the City’s announcement about the implementation of the Watertown Square Area Plan.

The Zoning Board of Appeals approved the planned 52-unit residential building at 108 Water Street on Wednesday night after designers made changes to exterior design of the building, along with some other alterations to the first plan presented in November. The condo building will have a mix of nine studios, 30 one bedrooms, 12 two bedrooms, and one three bedrooms. Eight of the units would meet the City’s affordable housing requirements. The building is five stories, with the fifth story stepped back seven feet as required in the Watertown Square 2 Zoning. One of the concerns raised by the board at the first meeting was the look of the ground floor that runs along Water Street and gets taller as the grade goes downhill.
The project at 33 Mt. Auburn Street was approved by the Planning Board. The five story building has one floor of commercial and four of residential. (Torrington Properties)

The board also granted a requested change for the project at 104 Main St., and got an update on the building going up across from the Watertown Library. 108 Water St.

(UPDATED on Oct. 21, 2025 at 2:20 p.m.: The first version incorrectly noted that the whole 24 acres of the proposed project were sold. Only 550 Arsenal Street were sold). Plans to turn the Watertown Mall and other properties on the north side of Arsenal Street into a life science campus appear to be over after the owners of the property sold to a Newton-based development firm. The Boston Globe reported that Alexandria Real Estate sold the Watertown Mall property in Watertown, which is located at 550 Arsenal St., to National Development for $100.25 million.
