In this episode of the Passive House Podcast Jay Fox interviews Vermont filmmaker Allie Rood about her documentary Prickly Mountain and My Design Build Life, which traces the design-build architecture movement that began in Warren, Vermont around 1963 and influenced design-build programs nationwide. Rood explains her personal connection through her father’s work in the community, the movement’s roots among Yale architects reacting against the designer/builder class divide, and ideas like Dave Sellers’ “Wild Beam Theory” of improvisational building. She contrasts early sculptural ski houses with a later sustainability-focused generation behind the Dimetrodon co-housing project and discusses Yestermorrow’s emergence as a design-build school. Rud also recounts the film’s 10-year production, funding and grant challenges, finding an editor, shifting to a personal narrative, and current festival distribution and screening plans.
