Perched above the Willamette River with sweeping views of Mount Saint Helens and the Portland skyline, this iconic residence represents a rare opportunity to own one of only two Oregon homes designed by modernist architect Richard Neutra. Commissioned in 1941 by renowned lily hybridizer Jan de Graaff and Macy's heir Peggy de Graaff, the home masterfully demonstrates Neutra's modernist vision while incorporating distinctly Pacific Northwest elements.Consulting with Neutra's son Dion and Columbia University's archives, the current owners have meticulously restored the home to its original design principles, marrying historical authenticity with modern comfort. Original elements like vertical tongue-and-groove cedar siding, custom Neutra hardware, and extensive built-ins are complemented by thoughtful updates, including double-paned windows and seismic upgrades.The main level, anchored by one of the home's four fireplaces, showcases Neutra's genius for seamlessly integrating indoor and outdoor spaces. Dramatic walls of glass frame unobstructed mountain, city, and river views, while floor-to-ceiling sliding doors extend the living areas onto two connected entertaining decks.Upstairs, the primary suite offers panoramic views, a gas fireplace, a private deck, and dual bathrooms sharing a generous shower. Two additional bedrooms on this level each include private bathrooms and walk-in closets. The lower level features two bedrooms, a workshop, and separate entrance with zonal heating, ideal for guest accommodations.The 0.85-acre property spans two tax lots, including a 0.25-acre buildable parcel shaded by mature trees. The level yard offers flexibility for future development - from a pool to a guest house or sport court - while preserving natural privacy. A three-car garage offers abundant storage.Set on a private road minutes from downtown Portland and Lake Oswego, the property lies within Riverdale School District, one of Oregon's highest-ranked districts.
