About This Home

9505 SE 43rd Street

Perched on a shy half-acre private lot, this architecturally significant mid-century modern home is a true masterpiece. Designed by renowned architect Peder H. Knudson, the home is a showcase of design and sophistication. It features striking floor-to-ceiling walls of windows that flood the interiors with natural light, along with multiple decks that seamlessly connect indoors and outdoor living. Its eclectic charm creates a calming, natural vibe. Surrounded by a Zen-like, park-like tranquility, this urban oasis has filtered water views from the main deck, where soaring eagles abound. The peaceful setting, on a dead-end street, secluded from neighbors, provides the perfect space to entertain or embrace a slower, more mindful lifestyle.
