The Bunker Hill Housing Redevelopment is a multi-phased project bringing new affordable and market-rate housing across 15 buildings in Charlestown, Massachusetts. There are a total of 2,699 units, including 1,010 affordable units, 50,000 SF of retail, 14,000 SF of community space, and seven acres of open space. All the buildings will consist of Mass Timber / Cross-Laminated Timber (CLT). This project is the largest public housing redevelopment in the history of Boston and will be the largest Passive House certified project in North America.

Stellata (Building M) is the first building of the larger redevelopment. The six-story building features 102 public housing rental units across 119,600 SF. The structure utilizes long-spanning Cross-Laminated Timber (CLT) floors on steel stud walls, which enabled a quicker turnaround on the floor-floor erection sequencing. This project utilized a variance to erect this building under the new IBC 2021 Construction Type IV-C and has fully exposed CLT ceilings.

The second building, Building F, consists of a nine-story, 265-unit CLT CFMF hybrid system on a steel podium.
