Seven projects totaling nearly 2.4 million square feet received approvals from the Boston Planning & Development Agency, including the largest affordable condominium project in Back Bay history and a $1.1 billion makeover of public housing in South Boston.

Boston-based Trinity Financial’s plans for 133 housing units at the Harvard Club property at 415 Newbury St. elicited opposition from owners of the nearby Elliot Hotel and some neighborhood residents, along with strong support for increasing the neighborhood’s affordable housing stock. The 237,000-square-foot project will include 23 income-restricted condos, including three that will be sold for $175,300.

Trinity Financial abandoned plans to build a boutique hotel on the private social club’s parking lot in 2019 because of neighborhood opposition, Vice President Abby Goldenfarb said.

The current proposal, estimated at $128 million, includes an 11-story building with 95 apartments, and a 3-story condo building containing 23 income-restricted units and 15 market-rate units.

Some neighbors objected to approval of a planned development area for the 1.1-acre site, which eliminates the need to seek variances from the Zoning Board of Appeals. Attorney David Linhart of Goulston & Storrs, representing the developers, said the PDA approval is a common mechanism for sites spanning more than an acre.

“It’s not that one zoning [mechanism] is a normal pattern and the other is unusual. They are different paths and they are both available,” Linhart said.

In South Boston, the first 1.4 million-square-foot phase of the Mary Ellen McCormack public housing complex redevelopment will replace 35 aging buildings with 1,300 housing units in eight new buildings, while converting a former boiler building into a community center.

The initial phase spans 18 of the 31 acres on the northern side of the complex off Old Colony Avenue. Upon completion, the first phase will include 1,310 housing units, of which 529 will be income-restricted, in eight buildings ranging to 19 stories. The project also includes 33,000 square feet of retail space.

“It is almost an enclave, segregated by geography as well as income brackets, from the rest of Boston,” WinnCompanies CEO Gilbert Winn said. “We’re going to be re-knitting pedestrians, retailers, consumers and all income levels to live together, while ensuring that every single person who lives there today remains there.”

Construction is scheduled to begin in 2024 and last up to 10 years, with timing of the three phases subject to funding availability. The Boston Housing Authority will assist tenants in finding temporary replacement housing during the construction

In Dorchester, a 9-acre commercial site between Interstate 93 and Morrissey Boulevard received planned development area approval for a seven-building complex totaling nearly 1.6 million square feet of office, lab and multifamily housing.

The project, led by developers David Raftery and Matthew Snyder, will include a new grocery store on the ground floor of one of three planned residential buildings. The property includes an existing Star Market.

Developers estimate a groundbreaking of the first phase, including an office-lab building and residential building, in 2025 or 2026, according to a BPDA memo.
