Newbury Street could soon see almost 100 new residential units with the proposed redevelopment of 415 Newbury St. and 374 Commonwealth Ave. in Boston’s Back Bay. 

Trinity Financial Inc. and the Harvard Club of Boston filed a letter of intent with the Boston Planning & Development Agency on April 16, proposing the redevelopment of land currently occupied by the Harvard Club of Boston and a parking lot. 

The existing Newbury Street-facing Harvard Club annex would be replaced with a new 123,000 square-foot, 11-story building with member, fitness and athletic facilities on the first three floors and approximately 95 residential units on the upper floors.

In addition, a three-story, 60,000 square-foot building would be built on the existing surface parking lot, bringing 38 residential units and parking for 125 vehicles.

The project will maintain vehicle passage connecting the mid-block alley and Newbury Street and add a new pedestrian passageway for safer access to Newbury Street, the application said. 

Developers said the project addresses the city’s need for transit-oriented housing units while also providing the Harvard Club with member and guest amenities.
