Blending classic elegance with state-of-the-art smart home features, this 4,841 square-foot, 4-bedroom, 4.5-bath home epitomizes modern elegance. Designed by acclaimed Architect David Mann of MR Architecture + Decor, its thoughtful layout can easily accommodate both leisurely living and grand entertaining. With over 100 feet of floor-to-ceiling, south-facing windows, each of the home's main living spaces is imbued with natural light. Accessed directly by an electronic-keyed elevator, guests are greeted by a spacious and inviting foyer that opens to a grand living and dining space, complete with a bio-fuel fireplace, white oak hardwood floors, and views of the terrace and beyond. Indoor-outdoor living is accomplished masterfully, with folding glass doors that, when opened, seamlessly disappear to bring the outside in. The terrace boasts its own BBQ unit and offers plenty of space for outdoor furnishings. The chef's kitchen is outfitted with top-of-the-line appliances and fixtures from Miele, Julien, and Grohe. It also features an elegant, olive maroon marble kitchen island and custom white oak cabinetry. A discreetly concealed, walk-in pantry with additional storage, appliances, and a separate sink allows for large-scale entertaining. Private and expansive, the home's 1,100-square-foot primary suite is situated in the west wing. It features its own south-facing terrace, wet bar and kitchenette, along with two oversized walk-in closets with custom built-ins. The spa-like, 5-fixture master bath is replete with a walk-in shower and a freestanding LaCava bathtub, all framed by driftwood marble and novelda cream limestone finishes. Radiant heated floors are found throughout. The luxurious penthouse also includes three spacious secondary bedroom suites, each with its own ensuite bath and custom walk-in closet. Additional highlights include a Savant Home Automation platform, which allows residents to conveniently adjust everything from lighting and A/C to music remotely from their phones. Numerous tech upgrades are found throughout, including electronic sheers and blackout shades on all windows, a top-of-the-line lighting system, and a SONOS home sound system. The residence also comes with exclusive access to two separate storage units.
