Seaport’s NEMA Boston opening to tenants

The 21-story, 414-unit NEMA Boston at 399 Congress Street in the Seaport District is opening in December.

Recall that the project filled one of Boston’s narrower development sites—so narrow it was dubbed the “sausage parcel”—and one that had drawn interest as far back as the middle of the previous decade. An earlier developer wanted to build a hotel there, but financing issues—and that unusual shape—got in the way. Another apartment project also came to naught. Miami-based Crescent Heights acquired the parcel in early 2016 for $36 million.

Its NEMA Boston is a kind of all-in-one affair. Tenants not only rent the ultra-modern spaces but are then also plugged into a suite of amenities that includes a fitness center and a rooftop lounge with grills.

The building, too, will host “a thoughtfully curated calendar of events that range from ski trips and speed networking to philanthropic endeavors, fostering a stronger community inside and out,” according to a release in the spring from Crescent.

All of this and the location in one of Boston’s faster-growing neighborhoods will, of course, cost tenants. Available studios range from $2,430 to $3,185 a month; one-bedrooms from $3,260 to $4,450; two-bedrooms from $3,905 to $5,760; and three-bedrooms from $6,560 to $8,910.

There are around 80 apartments currently available, according to the NEMA Boston website.
