There are some pretty ones, but most in the Cambridge/Somerville area are pretty ugly boxes. I don’t think another few decades will redeem them either, but would welcome being wrong.
Mid-Cambridge does have beautiful 5-6 story masonry buildings, which ironically, given the hot market, probably are economically feasible for a developer to build. Zoning prohibits this however.
As it stands, imho Somerville MA, is #1 in the nation on the (ugliness * cost) scale. Chain link fences, few parks, lots of concrete, and housing that outwardly looks the same as it did 50 years ago, but is 10X as expensive.
