A proposal for two six-story buildings with 56 homes, ground-floor retail and 67 belowground parking spaces was approved Tuesday by the Planning Board, embraced by neighbors of 2400 Massachusetts Ave. in North Cambridge and board members.ย
The project presentation for North Cambridge Partners LLC described a long process of neighborhood engagement since a previous attempt at developing the parcel was shot down in 2022 for getting ahead of a larger zoning process.
โI donโt think in all of the years that Iโve been on the board that Iโve seen such a great collaboration between the developer team, the neighborhood and the city,โ board chair Mary Flynn said before a vote. The board approved the project as a whole and left follow-up detail work to staff.ย
There would be a total 94,867 square feet of gross floor area on a 27,786-square-foot lot thatโs now a parking lot and a two-story retail building plus offices. The project, rendered with an industrial corrugated feel โ like a series of shipping containers in green โ would have different roof heights on different sides to respect the character of the neighborhood and avoid a high-rise approach: very low on Cedar Street, about 35 feet high on Alberta Terrace and moving up to different heights in the 50- to 68-foot range, with the tallest parts of the building being just under 70 feet tall. The buildingโs grounds will have grass and plantings, as well as patio space, though one reason for seeking a special permit from the board was to reduce the required green roof area.
Residents will own their homes, and โI havenโt seen too many ownership products come down the line,โ said Patrick Barrett, a lawyer representing North Cambridge Partners LLC, to the board. โPart of why we brought this before you is that the need for housing in Cambridge is very significant.โ
While a unit mix has yet to be determined, developers are interested in having some larger homes that would appeal to families, according to a presentation.
The Cambridge Redevelopment Authority will write down the purchase of 4,000 square feet of the buildingโs residential area โ about three or four units โ to be affordable to middle-income households earning in the range of 100 percent to 120 percent of the area median income, said Tom Evans, the CRAโs executive director. This puts the project above the number required to be affordable under inclusionary housing laws, which means about 24 percent of units will be below market rate.
Itโs part of a citywide initiative by the CRA to help deliver below-market homeownership, Evans said.
Potential retail destination too
There would also be some 7,161 square feet of retail on Massachusetts Avenue and in a corridor between structures that could remake the area as a commercial destination.ย
โThe Mass Ave retail quarter itself right now is not very strong, and we believe needs an anchor,โ Barrett said. He expressed confidence in being able to rent out the spaces based on consulting work his group has done at Market Central in Central Square, a complex at Massachusetts Avenue and Main Street that he said struggled at first to find the right mix of businesses.ย
Developers canโt predict what sort of businesses will move into their retail space, Barrett said. But theyโve committed to keep the building free of lab space, the result of nearly 10 public meetings in which neighbors voiced their preference. โEverything that weโve done is a reflection of those conversations with the community,โ Barrett said โ including moving the residential lobby to Alberta Terrace and away from the commercial presence on Massachusetts Avenue.
The mix of retail would begin with the buildingโs occupants and neighbors in mind. โWe look at these spaces as amenities for the building and for the community, and thatโs why the spaces are designed the way they are for some flexibility,โ Barrett said. There are large spaces, but โwe also are showing them broken up as micro unitsโ similar to what you would see at Bow Market, the retail complex in Somervilleโs Union Square. It has longtime tenants as well as pop-ups and incubating business concepts.
The new buildings would also likely have an amenity space for residentsโ parties and meetings, and a co-working space.
Brooke McKenna, Transportation Commissioner, said the developer will either build bike lanes or pay for the city to do it.
Approving neighbors

Abutters spoke with approval about the proposal, with some concerns about traffic and parking.ย
Brooke Mohnkern, who has lived on Cedar Street for 22 years, said he and his family are leery of the construction that will be required but excited that the parcel will no longer be an industrial parking lot. โWeโve endured dumpster fires, unbelievable graffiti, mass riots and fights too innumerable to count,โ he said.ย
Eric Johnson, who lives on Alberta Terrace, says he approves of the new building design. He has been heavily involved with the community outreach process since 2022 and doubts additional traffic will be a large concern in a neighborhood by Massachusetts Avenue. His primary issue is keeping a garage entrance on Harvey Street so it will not face Alberta Terrace homes โ because they can already hear the warning beeper from the nearby Trolley Square apartment building.ย
In addition to the public comment, the project arrived with several letters of support from neighbors, and โitโs very rare when you have so many folks coming in supporting projects that are right next to their house that will represent a disruption to them,โ Barrett said.
Excited board members
Elizabeth Whittaker, the founder and principal of Merge Architects, said the site presented an โextraordinaryโ shape, but her firm stepped up to the challenge of working with it. โWeโre trying to do an extraordinary building and not a big, banal building,โ she said.
The effort paid off in board comments as well as in a final vote of approval.
โThis is one of the few projects that has really excited me over the last few years,โ member Ashley Tan said, citing the importance of the proposed color and texture. โI love the balconies and terraces. Thatโs important in the urban context.โ
Member Mary Lydecker agreed, saying she โlovedโ the Cedar Street side of the project as โone of the most beautiful kind of sculptural housing. Itโs one of the most really thoughtful and context sensitive developments that Iโve seen.โ Member Diego Macias said he โwas really in awe. I thought it was a beautiful project. I was excited to see this in Cambridge.โย




What is not to like? No invasion of renters. 67 underground parking places so cars can dominate our future. The CRA coming up with public money so that a family of four making nearly $180,000 a year can buy an โaffordableโ unit. What will be the cost of the homes? What will the retail look like? Market Central continues to โstruggleโ and rather than serving the desires of the port community continues to lead to more gentrification. Of course the planning board likes this proposal. We need affordable home ownership for the working class, less dependency on cars and retail that does not gentrify. Is this development the answer?
