About This Home
This exquisitely updated five-bedroom Eichler seamlessly blends iconic mid-century architecture with refined modern design, sitting on a flat .31-acre lot. Originally designed by renowned architectural firm Jones & Emmons for Joseph Eichler, the home has been thoughtfully reimagined while preserving the clean lines, natural materials, and indoor-outdoor living that define its architectural legacy. A serene open-air atrium welcomes you into the heart of the home. The open-concept living, dining, and kitchen areas flow effortlessly together, with walls of glass and direct access to the surrounding outdoor spaces. Vaulted ceilings and beams enhance the sense of volume, while an exposed wood feature wall adds warmth and character. At the center of the home, the sleek designer kitchen features a quartz waterfall island, Carrara marble backsplash, premium stainless-steel appliances, an induction cooktop, a wine refrigerator, and generous pantry storage. The private primary wing is a tranquil retreat with direct backyard access and a spa-inspired en suite bathroom featuring a dual shower head and a double vanity. An adjacent fifth bedroom/office opens to the atrium, providing a flexible space. On the opposite side of the home, three generously sized bedrooms offer privacy and comfortable separation of space. The thoughtfully landscaped yard features redwood trees, well-landscaped grounds, and turf that create a peaceful setting. The expansive rear patio provides abundant space for outdoor dining, entertaining, and relaxation, equally suited for everyday living and special occasions. Located in Castro Valley's sought-after Greenridge neighborhood, the home offers a tranquil residential setting with convenient access to parks and trails at Greenridge Park, Cull Canyon Park, and Lake Chabot. Castro Valley BART and major commute corridors are within easy reach, providing excellent connectivity throughout the Bay Area.
