Nestled high in Kalithea, one of El Dorado Hills' most exclusive gated communities, this extraordinary custom 5,132 sq. ft. estate, not including a detached guest cottage with private bath and HVAC, offers luxury, privacy and exceptional craftsmanship on a beautifully landscaped and secluded .76-acre lot. Soaring 12-foot ceilings define the main level, where nearly every room features a custom ceiling treatment, including coffered beams, illuminated trays and arched soffits. The grand entry makes an immediate statement with a dramatic floor- to-ceiling stone waterfall surrounded by stately stone columns, rich travertine and illuminated display niches. Extensive custom cabinetry, premium Andersen windows and doors, and exceptional craftsmanship reflect the quality throughout. The expansive ground-floor primary suite offers true single-level living with a private sitting area, fireplace, two walk-in closets, heated tile floors and direct French-door access to the resort backyard. The chef's kitchen showcases Viking appliances, expansive stone surfaces, custom cabinetry and an oversized stone-clad breakfast bar, opening seamlessly to the family room and fireplace. Additional highlights include five full bathrooms in the main residence, an oversized executive office with adjoining fitness center, and an upstairs Tuscan-inspired billiard room with glass French doors and theater-ready media space. A climate-controlled 500-bottle wine cellar with tasting bar adds another distinctive touch. The private resort backyard features a heated pool and spa with waterfall, outdoor shower, outdoor kitchen, mature palms and expansive artificial turf. An oversized multi-car garage includes a rare extra-tall RV/boat bay. A premium 29-panel owned solar system and backup generator complete this exceptional offering.
