Project Description
The house reinterprets the vernacular form of local rural buildings, nestled among the maples at the edge of a hay field. Warmed by the sun, insulated with a thick coat of cellulose, it is a cozy nest for dreaming, living, growing.
This deeply personal project was designed by the architect to be her own family’s home and workspace. Designed and re-designed over several years as she observed the site through changing seasons, then constructed as an owner-builder at the height of the covid-19 pandemic with a talented team of local carpenters.
This is one of the first certified Passive House projects in Quebec. Thanks to its light-frame wood construction and extensive use of cellulose insulation, which sequesters carbon by diverted paper from waste streams, the house has a lower embodied carbon footprint than if it had been built to only meet the minimum requirements of the Quebec Construction Code.
