This hotel-branded tower in the Seaport won’t have a hotel. Here’s what it will have.

A luxury hotel brand emerging in Boston’s Seaport District has no hotel: The St. Regis Residences, Boston will make the Marriott-owned brand’s first standalone condominium development.

“We envisioned a more private experience for these homes, without the transient nature of a hotel,” said the building’s developer, Jon Cronin, principal of Boston-based Cronin Development.

Residents will have exclusive use of the tower’s 12,000-square-foot fourth-floor amenity suite, which includes a lounge and bar with an outdoor terrace, an infinity-edge pool and hot tub, an exercise room and a sports simulator, and a media room. Parking via 24/7 valet service will be available on three levels of underground garage, too.

Above the subterranean levels, the 22-story waterfront condominium development will have a public restaurant — described as an all-day American-style bistro — on the first and second floors. There will a private entrance for residents, who will be offered preferred seating and private and in-home dining. There will also be hotel-level doorman and concierge services, as well as a “butler” for day-to-day chores, including turndown service.

“One of the appeals of the St. Regis brand is an exquisite level of service and luxury,” Cronin said. “Our buyers are absolutely looking for that when they choose one of our homes.”

The building’s exterior, courtesy of late Boston architect Howard Elkus, will have a cantilevered, twisted, and “pleated” aspect inspired by billowing sails, giving the building both inner and exterior appeal.

“The innovative twisting facade provides many more floor plans with views than a traditional rectangular building shape could offer,” Cronin said.

Occupancy for the 114 homes — which will range from 950-square-foot one-bedroom, one-bath units to 8,000-square-foot six-bedroom penthouses (starting at $1,700,000, including parking) — is expected next spring. The homes will feature floor-to-ceiling windows, as well as walk-out or Juliet balconies with Airlux sliding doors.

Sales, though stalled by the pandemic, are vigorous, Cronin said.
