A Green Portland Home Built to Passive House Standards

Collection by

A modern, energy-efficient design creates an authentic connection between work and home.

After years of working from their home in Portland, Oregon, architect Jeff Stern and his wife, a felt artist, decided to build a house that better suited their lifestyle. The couple envisioned a modern, energy-efficient residence. “Since I was the architect, general contractor, certified Passive House consultant, and owner, I was able to tune the design for optimized performance and keep things simple,” says Stern, founder of In Situ Architecture. Built on an oversized lot the couple already owned, the Skidmore Passivhaus physically connects a detached studio and residence while maintaining a feeling of passing through outdoor space. The dark-stained, rough-sawn cedar siding's appearance will change naturally over time—a nod to traditional Northwest architecture. The home’s open floor plan is enhanced by cost-effective materials like painted sheetrock, concrete floors, and plywood cabinets. Brightly painted doors and laminate countertops provide splashes of color throughout the Passive House–certified residence, which produces nearly all of its electricity via a small, roof-mounted photovoltaic array.

While the home’s simple, boxy forms starkly contrast with surrounding residences, its compact shape and modest scale help it fit into the traditional neighborhood without calling attention to itself. The house was built around a large birch tree, with dwarf fountain grass and porcupine grass planted in front. A weeping blue atlas cedar provides a focal point near the front door.
