It's 320 residential units.....and in Everett....in a neighborhood described by the OP as "It's a warehouse district with single family homes just scattered through, one or two per block..." That is a major turn towards urbanity.

There has been so much change in that area, other multifamily projects include Pioneer (ha.), Vero and V2 (technically in Chelsea), Mason, Maxwell, Anthem, and the one under construction on Revere Beach.
