The Unicorn on the Cul-de-Sac! Engineered-not just owned-for 43 years by a Southwest Research Institute engineer. Over $100,000 in intentional upgrades, not for resale... but for a lifetime of living well. This one-of-a-kind home was meticulously improved with durability, efficiency, and comfort in mind. Cement fiber siding offers the benefits of masonry with insurance advantages. Premium Pella windows and a high-end sliding door open to a private backyard retreat anchored by a stunning mature oak. Inside, you'll find rich wood flooring, a fully remodeled kitchen with custom cabinetry and clever engineered storage, and beautifully updated bathrooms. A custom-built Murphy bed and built-in study maximize space with purpose and precision. Major system upgrades most homes never receive: metal roof, solar panels, 75-gallon water heater, and a fully replaced metal ductwork system with room-by-room airflow control-designed for superior efficiency and comfort. Situated at the end of a quiet cul-de-sac with no neighbor to the right and a peaceful greenbelt behind. Xeriscaped front and back yards, rainwater collection system, and premium leaf-repelling gutters keep maintenance low and efficiency high. Homes like this are rare-thoughtfully designed, meticulously maintained, and built for someone who values quality over shortcuts.
