Perched on an expansive corner lot in coveted North Berkeley, 2301 Oak Street is an exceptional mid-century modern residence that has been thoughtfully revitalized while honoring its original architectural integrity. Designed by Jaroslav J. Polivka who worked closely with Frank Lloyd Wright on some of his most famous projects-this home offers a rare blend of design pedigree, flexibility, and everyday livability. Spanning approximately 2,635 square feet, the home features 4 bedrooms and 3.5 bathrooms, with a highly versatile layout that accommodates both single-family living and income potential. The upper level lives as a spacious 3-bedroom, 2.5-bath residence, while also offering the option to create a separate studio with its own entrance and garden. True to its mid-century roots, the living room is anchored by a striking fireplace and framed by floor-to-ceiling windows that capture sweeping bay views and lush garden outlooks. A distinctive custom gong doorbell adds a rare and memorable detail. The dining area features a stylish mid-century wet bar and opens seamlessly to an outdoor deck-perfect for entertaining and al fresco dining. The remodeled kitchen stays faithful to the home's aesthetic with terrazzo-style flooring, refinished original cabinetry, and thoughtfully integrated modern upgrades. Throughout the home, refinished hardwood floors, updated lighting, and carefully curated finishes reflect a cohesive mid-century design language. Upstairs bedrooms are filled with natural light, offering floor-to-ceiling windows and breathtaking bay views. One bedroom includes original built-ins. All bathrooms have been fully updated with mid-century-inspired tile, vanities, and fixtures. The lower level includes a remodeled studio unit with a new kitchenette, updated bath, and private feel-ideal for guests, rental income, or extended family. A detached office provides a perfect work-from-home retreat. Outside, the property offers privacy and a connection to nature. The landscaped gardens, largely supported by irrigation, create a peaceful setting where deer are often seen passing through. Generous parking includes a two-car garage, five-car driveway, and additional street options.
