About This Property

A true private resort unlike anything available in Lake Mathews! Situated on 2.29 acres on one of the area's premier view lots with breathtaking panoramic views of Lake Mathews, this extraordinary estate features an approx. 2,560 sq. ft. 3-bedroom plus office/den main residence and an approx. 550 sq. ft. detached ADU/guest house, offering over 3,100 sq. ft. of combined living space.

The remodeled interior showcases vaulted ceilings with exposed wood beams, a chef's kitchen with custom shaker cabinetry, quartz countertops, oversized island, premium stainless steel appliances, professional-grade gas range, designer hood, remodeled laundry room, and a spa-inspired primary bath with a custom walk-in tile shower and frameless glass enclosure. The detached ADU/guest house includes a bedroom, full bath, and kitchenette, making it ideal for multigenerational living, guest accommodations, rental income, or potential Airbnb use.

The backyard is an entertainer's dream, highlighted by an approx. 80,000-gallon resort-style pool with an oversized elevated spa, waterfalls, Baja shelves, tanning ledges, illuminated water features, and dramatic fire bowls. The covered pavilion features a grand fireplace, built-in TV, refrigerator, serving bar, and lounge area overlooking the pool and lake. A custom BBQ station, multiple pergolas, covered outdoor dining, lake-view fire pit lounge, private courtyard with water feature, lush lawns, mature landscaping, walking paths, and a custom playground complete this incredible outdoor retreat.

An approx. 20' x 70' detached workshop with gated access provides covered space for RVs, boats, collector cars, equipment, hobbies, or a home business. A second workshop, paid solar, Tesla EV charger, expansive concrete parking, and approx. one acre of flat usable land offer endless possibilities for toys, additional structures, equestrian amenities, or another ADU.

Located in unincorporated Riverside County, this unique property offers potential for a short-term vacation rental (Airbnb), private retreats, reunions, and special events. Rarely does a property combine panoramic lake views, a detached ADU, resort-style amenities, massive workshop space, usable acreage, and unmatched entertaining into one unforgettable estate.
