Critical Mass: Scaling Passive House at Bunker Hill

The Bunker Hill Housing Redevelopment in Boston stands as a pioneering example of large-scale passive house implementation, aiming to deliver 2,699 mixed-rate housing units across 15 buildings. This panel discussion and presentation spotlights the all-star Bunker Hill team, including Nick Nigro (Leggat McCall Properties), Ray Kettner (Stantec), Andrew Steingiser (RDH Building Science), and Gregg Walsh (Suffolk Construction). As part of our “All-in!” theme for 2025, this discussion shares invaluable lessons learned from the design and construction of Building M, Bunker Hill’s inaugural structure.
