We transformed this charming 1922 bungalow located in Portland’s Historic Irvington neighborhood and listed on the National Register of Historic Places into a more spacious and comfortable modern home. While carefully preserving the original façade, we expanded the footprint from 800 to 1,750 square feet, creating four bedrooms and three bathrooms. The renovation features comprehensive energy upgrades and a whole-house heat recovery ventilation system that provides a continuous supply of fresh, filtered air. Certified Earth Advantage Platinum, the home also includes a high-efficiency mini-split heat pump, custom Pacific madrone cabinetry, and a central vacuum system.
