Rare opportunity awaits at 25582 Rangewood Road, ideally positioned on a peaceful cul-de-sac in prestigious Nellie Gail Ranch. Set on an exceptionally flat and private lot of nearly half an acre, this sought-after single-story residence offers an open floor plan and is just steps from Gallup Park, making neighborhood concerts and community events effortlessly accessible. The vision and groundwork for a truly one-of-a-kind estate are already complete. Architectural plans, engineering, HOA approval, and city permits have all been secured, accompanied by comprehensive landscape plans and detailed design renderings that bring the finished vision to life. The approved plans add approximately 500 square feet, creating more expansive bedrooms, additional dedicated en-suite bathrooms, a separate laundry and mudroom, and a striking modern exterior with a redesigned entry and updated siding. The already finished garage also offers ample overhead attic storage. A fully owned solar system is already in place and designed to support the planned expansion. The expansive grounds also feature what may be Nellie Gail’s finest custom chicken coop, bringing a distinctive touch of charm and elevated ranch living to this exceptional property. Beyond the home, the Nellie Gail community is a draw in its own right. Low monthly HOA fees cover security, trail maintenance, and baseline membership to the swim, tennis, and pickleball club, with access to a clubhouse, restaurant, swimming facilities, parks, tot lots, and approximately 25 miles of scenic trails. Freeways, premier shopping, and world-class beaches are all within easy reach. With its rare combination of privacy, usable land, single-level living, coveted cul-de-sac location, fully owned solar, and construction-ready plans, this is far more than a remodeling opportunity. It is the chance to complete a custom dream estate in one of Laguna Hills’ most desirable communities, without spending years navigating the planning, design, and approval process.
