The Alta Brigham Square apartment complex on Mill Street has sold, roughly a year after it opened.
Before developing it, Wood Partners, the largest multifamily housing developer in the nation, purchased the four-acre site at 30-50 Mill St. for $5.6 million from Cambridge Savings Bank, which foreclosed on the property in August 2008.
The old 85,000-square-foot Brigham’s headquarters was demolished in the fall of 2011.
The new development is 135,000 square feet and includes 18 studios, 35 one-bedroom units and 63 two-bedroom units, as well as amenities, like a fitness center, and a separate building with 3,090 square feet of retail space, which, in part, is expected to be an urgent care clinic run by Steward Health Care.
Intercontinental Real Estate Corp. is based on Soldiers Field Road in Boston.
