In this episode of The Passive House Podcast, Zack Semke chats with Nick Nigro of Leggat McCall about the Bunker Hill Housing Redevelopment in Charlestown, Boston, a phased replacement of 42 aging WWII-era public housing buildings into 2,699 mixed-income units. Nick explains how the team committed to Passive House from day one and is using a repeatable “kit of parts”—precast lateral-load-bearing cores, prefabricated load-bearing exterior panels, and CLT floor systems—to improve speed, reduce temporary work, and lower both carbon and cost through iteration across 15 buildings. He describes early modeling, enclosure mockup testing, and construction-sequencing innovations like using the permanent elevator as a hoist.
