Project Description
The Gabion house is designed for today and tomorrow. This single-family custom home features a post-disaster structural system, is designed to Passive House standards and will be Living Building Challenge Petal certified.
The house is placed in the northeast corner to retain as much of the Gerry Oak meadows as possible. Two principal gabion walls create thresholds and boundaries within the house and the site. The one-level home is designed to enable ageing in place and is appropriate for the sight-impaired owner.
