Property Description

Harcourts Certified & Transparent Non-Distressed Luxury Auction Platform! Bidding to Start from $8,000,000. Live Auction Thursday, June 18th @ 12pm. Buyers do not need to wait for the auction date to submit an offer and stop the auction - loan or cash. Introducing the World-Class Chateau Dumont, an unequaled compound in Rancho Mirage. Experience the apex of desert luxury at this resort-style private estate, a true family sanctuary set on nearly five acres in the heart of Rancho Mirage. Privately gated with a grand double-drive entry and porte-cochere, this palatial Mediterranean-style compound spans more than 18,000 square feet of refined elegance and sophistication. From nearly every vantage point, the estate captures breathtaking mountain, lake, and garden views. The premises feature 15 bedrooms (inclusive of a private office), 13 bathrooms, including a two-bedroom, two-bath detached guest house with full amenities. Inside, a striking Great Room welcomes guests with expansive living and entertaining spaces, complete with a custom bar, wine tasting room, formal dining lounge with fireplace, home theatre, and a billiard parlor/game room. The chef's gourmet kitchen, equipped with professional-grade appliances and a separate butler's prep kitchen, makes hosting both effortless and elegant. Additional amenities include a private gym, elevator, and garage space for up to five vehicles. The primary retreat offers an exceptional sanctuary featuring a sitting area with fireplace, built-in office, wet bar, and a spacious walk-in closet with custom organization and abundant storage. French doors open to a covered lanai with misting system, creating seamless indoor-outdoor living. The spa-inspired primary bath is equally impressive, highlighted by a domed skylight that fills the space with natural light, an indoor garden, double enclosed shower, and two water closets. The retreat is further enhanced with a private sauna and a sensational Roman rotunda spa. Designed for large-scale entertainment, the Great Room can easily be transformed into a Grand Ballroom for significant events and celebrations. Multiple French doors open onto a Grand Terrace with a central fountain, overlooking the resort-style pool, spa, and cascading waterfalls. Outdoor living is equally extraordinary, featuring a full outdoor kitchen and BBQ area, as well as a covered dining terrace with fireplace. The estate's private lake, view pavilion, championship tennis court, pickleball and basketball courts, and sweeping panoramic views complete this remarkable offering. Equipped with a natural-gas microturbine that generates on-site electricity, a private water well for landscape irrigation and refilling the three on-site lakes, state-of-the-art security, and full smart-home automation, this property combines luxury with sustainability. With its expansive grounds and premier desert location, this truly singular estate unmatched anywhere in the world also provides an extraordinary setting for charitable events, fundraisers, galas, and other special gatherings. Proof of income is required for all private showings.
