Welcome to this rarely available, fully remodeled Castillo Penthouse, ideally positioned at the end of a picturesque cul-de-sac and offering exceptional privacy. This residence has just undergone a comprehensive custom renovation featuring new wood-plank tile flooring and fresh paint throughout, along with a brand-new gourmet kitchen showcasing white soft-close cabinetry, elegant quartz countertops, new appliances, a gas cooktop, and premium Kohler plumbing fixtures. The spa-inspired bathrooms are appointed with quartz countertops, a soaking tub, frameless glass showers, new vanities, Kohler fixtures, and dimmable, anti-fog mirrors. The penthouse offers two expansive living and entertaining areas, providing an ideal layout for both everyday living and hosting guests. Enjoy nearly 700 square feet of covered lanai space overlooking a serene preserve—one of the most tranquil settings in all of Tiburón. Southwestern exposure delivers breathtaking sunset views, while a second balcony facing the fountain cul-de-sac offers the perfect spot for morning coffee. Additional recent upgrades include custom-built closet systems, designer light fixtures, a new washer and dryer, and a brand-new tankless water heater. Electric shutters on all lanais provide added peace of mind while away. Every detail has been thoughtfully curated. Building renovations have also been completed and include a new roof, new screens, fresh exterior paint, and a beautifully remodeled lobby. The attached two-car garage provides direct access to your private elevator, which opens into the penthouse featuring soaring 10’6” ceilings. A SIGNATURE MEMBERSHIP ($50K value) IS INCLUDED - offering immediate access to exclusive Golf and Social Memberships, and all of the amazing Ritz-Carlton amenities.
