Heartwood Residence — A Modern Riverside Masterpiece
The Heartwood Residence, designed by William Kaven and completed in 2021, is a striking example of modern residential architecture that harmonizes nature, design, and history.
Located in the Oak Grove neighborhood of Portland, this single-story home sits gracefully along the banks of the Willamette River, offering sweeping views that connect residents to both the natural landscape and the area’s industrial heritage.
Design Philosophy
At the heart of the home—both literally and conceptually—is a central maple tree, which anchors the entire architectural layout. The house is designed around this living focal point, creating a seamless dialogue between indoor and outdoor spaces. Large glass openings, open-plan interiors, and carefully framed sightlines ensure that nature is always present.

This home isn’t just a place to live—it’s a thoughtful architectural statement that merges environment, culture, and modern design into one cohesive vision.

Embracing the Riverfront
Nestled along the east bank of the Willamette River in Portland’s Oak Grove neighborhood, the Heartwood Residence is a compelling expression of modern riverside living. The home captures sweeping panoramic views of the river, where shifting wildlife, boat docks, freight barges, and a historic early 20th-century railroad bridge quietly narrate the city’s industrial past.
At the center of the design stands a majestic maple tree—an organizing element that shapes the entire spatial experience. The architecture flows seamlessly from riverfront to courtyard, creating a continuous dialogue between nature and built form.
A Multigenerational Haven: Privacy and Togetherness
Designed with flexibility in mind, the residence responds to the needs of a family who regularly hosts extended stays from friends, children, and grandchildren. The solution is a compound-like layout that balances connection with privacy.
A detached casita offers comfortable accommodation for up to two guests, while the main house remains a private retreat. Upon arrival, visitors are welcomed into a generous courtyard inspired by the architects’ New Mexico roots. From here, a glazed wall draws the eye straight through the living space to the river beyond—an intentional gesture that immediately establishes openness and warmth.
Blurring the Lines: The Heartwood Courtyard
With expansive floor-to-ceiling glazing, the courtyard transcends its traditional role and becomes a liminal space—neither fully indoors nor outdoors. This transparency allows natural light and western views to flood the home, dissolving boundaries and enhancing the connection to the surrounding landscape.
Showcasing Timeless Elegance: Interior Design
Inside, the residence serves as a curated backdrop for a sophisticated collection of Modern American and Italian furniture. The material palette is restrained yet rich in texture, featuring:
-
Rift-sawn white oak cabinetry
-
Corian countertops
-
Exposed aggregate concrete floors
-
Chevron-patterned oak flooring
-
Built-in fireplaces and smooth plaster walls
These elements combine to create an atmosphere that is both refined and deeply livable.
A Modern Addition: Exterior Design and Outdoor Living
Constructed from cedar, aluminum, and board-formed concrete, the Heartwood Residence introduces a contemporary identity within a neighborhood largely defined by mid-century ranch-style homes.
The rear patio extends the living experience outdoors, centered around a wood-burning fireplace and framed by views of the Lake Oswego River Bridge and nearby riverfront parkland—offering a tranquil yet visually dynamic setting.
Final Impression
The Heartwood Residence is more than a home—it’s a carefully orchestrated environment where architecture, landscape, and lifestyle converge. By balancing openness with intimacy and modernity with context, it stands as a distinctive and thoughtful addition to Portland’s architectural landscape.
