Stunning and rare midcentury gem in the heart of the Altos de Monterey neighborhood of South Pasadena, nestled on over half an acre of land. This gorgeous post and beam home is one of only 32 residences designed by coveted architect James Allen Walter. Meticulously cared for by the same family for over three decades, this post and beam home boasts vaulted ceilings, two atriums, and walls of glass that accentuate its spacious layout with an abundance of natural light. The property features a large, concealed primary suite, two generously sized bedrooms, and a versatile den that can serve as a fourth bedroom, each offering direct access to an atrium or the backyard, beautifully blending the lines between indoor and outdoor living. The galley kitchen, with its original custom walnut cabinets and sliding glass panel windows, seamlessly connects service to the dining room and atrium. A dramatic open living room leads to a spacious patio and backyard, perfect for entertaining. Throughout the home, you'll find original custom walnut cabinetry, built-in desks, and bookshelves. Recent updates include a new roof, electrical wiring, copper plumbing, and sewer liner. An oversized two-car garage and additional carport spaces, at the end of a long driveway provides ample parking. This property is a true architectural masterpiece and an extraordinary opportunity to reside in a living work of art!
