When the 20-story Montaje apartment building opened at Somerville's Assembly Row in 2015, it came with the distinction of being the tallest building in the city.
It wouldn't last.
Six years later, Montaje was surpassed by a neighbor a block away: A luxury apartment building called Miscela, which was four stories and 32 feet taller. But Miscela's reign didn't last, either.
Two miles away, in Union Square, a residential tower that's 25 stories and 299 square feet high is nearing completion as part of a major mixed-use development surrounding a new MBTA Green Line station.
It turns out that tower likely won't be the tallest for long, either. Up next is 74M, a life sciences office tower between Assembly Row and I-93. The tower will technically fall short of the Union Square tower by four feet - but beat it by 30 feet when 74M's mechanical screen, which shields mechanical equipment from view, is factored in.
For generations, Somerville was known for the three-decker homes that line its compact streets. But these days, Somerville is building towers - and it doesn't look like the trend will stop soon.
In Union Square, the Union Square development will include a second building of more than 20 stories, a 373-unit tower slated for a later phase. Assembly Innovation Park, which includes a 12-story building now under construction next to the 74M tower, will be followed by two other buildings in later phases. They're planned to be roughly the same height.
Two neighboring cities, Cambridge and Everett, haven't been known for towers, either, but that's also changing.
Cambridge has already added its new tallest tower, a 454-bed graduate dorm for MIT students on Main St.
Site work has begun on what will be the city's next tallest tower - notably residential in use, not life sciences. The 37-story residential tower at 121 Broadway will total 476 feet, easily the city's tallest.
That tower could be eclipsed soon after. A redevelopment plan by MIT for the federally owned Volpe Center between Broadway and Binney Street calls for a tower of up to 500 feet.
In all, Cambridge has at least 10 towers built in the last decade or now in at least early phases of construction that are at least 250 feet in height. Before then, the city had only 10 such buildings in total.
Across the Mystic River, Everett is also going taller. It already has the 350-foot Encore Boston Harbor, which opened in 2019, and may have two more towers, both residential and both permitted for construction. One, called The Sophia, is proposed for 249 feet on Second Street and another, SKY Everett, would stand 236 feet on Spring Street.
One other Boston suburb has also hit a new high: Quincy's Chestnut Place, a 15-story residential tower, became the city's tallest when it opened in 2020.
