Welcome to Calypso Court, a name synonymous with rhythm, mystery, and escape, this private estate is a world apart. Designed for those who value discretion as much as distinction, this exceptional residence offers a lifestyle that feels both indulgent and effortlessly serene. Located high in the prestigious Alta Loma area within the gated community of Haven View Estates, this resort-style property sits on a rare 1.25-acre double lot (two APNs) and captures sweeping city-light views. The elevated setting provides a sense of privacy and exclusivity rarely found in the area. Spanning approximately 5,500 square feet, the residence features seven bedrooms (or 5 Brs + Office+ game room) and six bathrooms, thoughtfully designed to accommodate both grand entertaining and comfortable everyday living. Expansive living spaces are filled with natural light and enhanced by seamless indoor-outdoor flow. The grounds are truly impressive, offering a private multi-use sports court suitable for tennis, pickleball, and basketball, along with a resort-style pool and spa and expansive outdoor areas ideal for relaxation and hosting. A three-car garage is complemented by a highly desirable fully finished double RV garage, which has previously hosted large gatherings and provides exceptional flexibility for recreational vehicles, collectors, or additional storage. Calypso Court is not simply a home—it is a destination. A private world tucked away from the everyday, yet conveniently located near shopping, dining, and major transportation routes, this estate combines privacy, scale, and panoramic views, making it a rare offering in one of Rancho Cucamonga’s most sought-after hillside communities.
