Located in the heart of Alpharetta's prestigious Rivermont corridor, and being offered for the first time to market in 2 decades is 570 Matterhorn Way. A masterfully reimagined architectural retreat that blends modern elegance with timeless design. Originally built in 1978 and exquisitely renovated with much acclaim by architect Peter Bourget, this 4-bedroom, 3 full and 2 half bathroom residence is privately situated on a tranquil cul-de-sac backing to the Rivermont Golf Course. The multiple level layout offers dynamic living spaces filled with natural light, soaring ceilings, and clean lines. The main floor features a designer kitchen equipped with high-end appliances including a built in Gaggenau coffee station, Viking cooktop, Wolf oven, Miele dishwasher, and Gaggenau refrigerator/freezer-anchored by a striking marble island and custom Italian cabinetry. Formal and informal dining areas glow under imported Italian lighting and open to a tree-lined floor to ceiling view. One level down, the expansive primary suite serves as a private sanctuary with multiple custom closets, a serene soaking tub room, a walk-in steam shower, and floor-to-ceiling windows that frame the lush landscape. The lower level transforms into an entertainer's dream, with a full home theater wired for surround sound, a lounge with fireplace, pool table, a full size Sub-Zero wine storage, an equipped kitchenette with Gaggenau cooktop and Bosch dishwasher, and seamless access to a Mediterranean-inspired courtyard complete with fireplace and exquisite al fresco dining. Outside, enjoy multiple sun and covered decks overlooking the woods. The rear exterior stairway winds from the tiled patio past the fountain to the tiered front garden. A wooded and spacious backyard that opens directly onto the golf course. Modernized with ethernet throughout for sound, security, and smart integration, plus a new tankless water heater, EV vehicle charger and updated HVAC, the home is both beautifully appointed and turnkey ready. Located within top-rated school zones-Barnwell Elementary, Haynes Bridge Middle and Centennial High-and just minutes from Avalon, North Point Mall, Big Creek Greenway, and the Chattahoochee River trails, this home offers an incredibly rare opportunity to live luxuriously in one of metro Atlanta's most sought-after communities.
