BOSTON—In about a year, another major mixed-use tower project will break ground in the Seaport District here.

South Boston-based Cronin Holdings LLC filed a letter of intent on Monday with the Boston Redevelopment Authority on its proposed $200-million project at 150 Seaport Blvd. The plan calls for the construction of 263,000 square feet of residential space and 12,000 square feet of retail space on the ground floor and second floor of the property, along with an open-air deck. The retail space will be reserved for retail shops and restaurants.

The 22-story tower building will offer 110 residential condominium units, a three-level underground garage as well as enhanced pedestrian access to the waterfront via a connection of the Boston HarborWalk between Pier 4 and Northern Avenue. The company expects to begin construction in early 2017 with a projected completion in 2019.

According to Cronin's filing with the BRA, the project will require Large Project Review under Article 80 of the Zoning Code.

"The project will mend a hole in the urban fabric by replacing an existing one- and two-story building with a vibrant mixed-use development providing an inviting, pedestrian-friendly environment that will attract people to the area even after the end of the work day," Jon Cronin, Crown Holdings CEO states in the firm's letter of intent to the BRA.

Cronin says a December speech by Boston Mayor Martin Walsh urging developers to build more architecturally significant buildings caused him to rip up earlier design plans that sketched out a "striking" and "cost efficient" tower. He says, "We decided to meet that challenge, and directed Elkus Manfredi to start from scratch. The result is a magnificent building that will add immeasurably to this dynamic district and to the vitality of the City of Boston."

The new plan features a twisting and angular design that Cronin says evokes "the nautical heritage of the location while providing a contemporary and transparent look worthy of the Innovation District."

"150 Seaport Boulevard is a unique site on the Boston waterfront in that it is the East Coast terminus of transcontinental Highway 90," adds Elkus Manfredi principal Howard Elkus. "As such it is a gateway to Boston Harbor and the City of Boston, and any building on this site needs to celebrate this remarkable moment. Our initial iconic design was inspired by the architecture of the sails that have historically characterized this harbor setting."

The project is expected to create 450 construction jobs and more than 200 permanent jobs. When completed, 150 Seaport Blvd. will provide $3.6 million in annual tax revenue to the City of Boston, Cronin states in a prepared announcement.
