For the last year and a half, Ken Ward and Andrée Zaleska have been rehabbing a 100-year-old former neighborhood store in the Boston neighborhood of Jamaica Plain. They’re converting it into a home for their combined family, a community gathering place, and a zero-carbon demonstration home to inspire others — and sharing their journey in the special series Coming Home: Chronicling the (re)invention of the JP Green House.

The firm overseeing the project, Placetailor, specializes in creating homes on the Passive House model, in which supertight insulation and careful use of passive solar create a building that requires no heating source. The JP Green House will be one of the first Passive House rehabs in the U.S. Photographer Leise Jones has documented the work as it progresses.
