Big changes could be coming to the former Carney Hospital site in Dorchester.

According to the Boston Business Journal, HYM Investment Group and My City at Peace are expected to file a Letter of Intent this week for the redevelopment of the former Carney Hospital campus at 2100 Dorchester Ave.

The proposed $850 million project would redevelop the 12.8-acre site into a new “Dorchester Health Campus” centered on restoring healthcare access, expanding housing options, creating workforce development opportunities, and improving neighborhood connectivity in Dorchester.

The redevelopment proposal outlines approximately 970,000 square feet across five new buildings dedicated to healthcare, healthcare education, housing, and neighborhood-serving retail and community uses. The project architect is CBT Architects. The site is currently owned by insurance and institutional funds managed by Apollo Global Management, which previously held a mortgage on the properties.

In a joint statement, Thomas N. O’Brien, Managing Partner and CEO of HYM Investment Group, and Rev. Jeffrey Brown, Founder and CEO of My City at Peace, said:

“Today’s Letter of Intent filing marks an important step forward in reimagining 2100 Dorchester Avenue as a vibrant, community-centered health and housing destination for Dorchester. This filing reflects extensive community feedback and a shared commitment to restoring healthcare uses on campus, expanding local housing opportunities, and enhancing connectivity on a site that has long been a cornerstone of the neighborhood.”

The statement also noted that the filing kicks off the city’s Article 80 review process, with more community meetings and neighborhood input expected as plans move forward.

The 12-acre site has remained a major topic of conversation since Carney Hospital closed in 2024, with many residents continuing to advocate for healthcare services to remain part of the property’s future.

It would be nice to see a dedication to the first hip replacement in the U.S.
There are probably many positive stories of healing at that hospital, instead of loss of loved ones.
I would love to know where that light colored brick was made. It looks like brick made in England.

Why waste this much money? The existing buildings need a paint job and minor repairs. These old buildings were build to last for 100 years or more. New buildings fall down in less than 40 years.

Please save Carney Hospital and do not pass this to build this.
