Experience the pinnacle of modern luxury in this architectural masterpiece known as the 'Art House,' a rare blend of art, design, and nature. Perfectly positioned atop coveted Mount Tiburon,' this private estate offers breathtaking, panoramic views of the Tiburon Peninsula, Golden Gate Bridge, San Francisco Bay, and Sausalito. Set on expansive, beautifully landscaped front and back yards, the home seamlessly integrates indoor and outdoor living with meandering garden paths, lush greenery, and vibrant outdoor entertaining areas. Multiple terraces, a sunny pool site, and a commercial-grade built-in BBQ make this the ultimate retreat for hosting or relaxing in style. In addition, the back yard is securely enclosed for privacy and also contains a separate, self-contained structure which can be designated for use as a studio, gallery, office or flexible space. Inside, dramatic soaring ceilings and a striking spiral staircase welcome you into a light-filled, gallery-inspired interior curated by renowned designer Gary Hutton. The residence includes a stunning library, office, media/recreation room, gym and a one-person elevator servicing all three levels. The upper-level contains a primary suite that is a true sanctuary, complete with a marble fireplace and a large private terrace above the trees, and awe-inspiring views across San Francisco Bay. It also contains four additional bedrooms, one of which is outfitted as a complete office, that are well separated from but easily accessible to the primary suite. Numerous custom design touches like a one-of-a-kind mid-century modern steel and glass shower enclosure with a uniquely pivoting door in the spa-like bathroom highlight the home's unique artistic pedigree. Additional features include a 3-car garage with ample off-street parking for an additional 8 - 12 cars, three zone whole-home air-conditioning and heating and a location just steps from open space and minutes from downtown Tiburon's charming shops, restaurants, and ferry service.
