RARE 4000 SFT SINGLE STORY POOL HOME. Designed in 1947 by the esteemed architect Sylvanus Marston, this Historic Hacienda Pool Home is not only a testament to timeless elegance and unparalleled craftsmanship but also holds the distinction of being the last house Marston designed. Nestled in Riverside's sought-after Queens Terrace tract in the Victoria Neighborhood, this property is truly one-of-a-kind. Marston, a dominant figure in Pasadena's architectural history, crafted designs that became the iconic backdrop to Pasadena's picturesque neighborhoods. His influence is evident in this 4,000 sq-ft adobe residence commissioned for Willard G. Babcock, a pioneering soil scientist. This spacious home boasts five bedrooms, including a maid's quarters and a gardner's room, perfect for multi-generational living. Enjoy a flowing open floor plan—ideal for entertaining or savoring tranquil evenings by the wood burning/gas fireplace. The property's landscape is a vision with native drought-resistant plants and mature fruit trees, creating a shaded retreat. The backyard swimming pool invites relaxation, further enhancing the sense of a private oasis. A grand circular driveway, adorned with new pavers and complemented by a water fountain, leads to a shaded Hacienda-Style front porch. Modern upgrades seamlessly blend with the home's historic charm, featuring a newer roof, updated copper plumbing and electrical systems, soft water system, central heating and air, new dual-pane windows, plantation shutters, and French doors. Located a stone's throw from the Historic Victoria Country Club and showcasing Marston's distinctive blend of simplicity and grandeur, this property offers a unique blend of history, luxury, and architectural brilliance.
