Set within Rio Vista, arguably Mahwah’s most coveted neighborhood, this distinguished residence is privately positioned at the end of a cul-de-sac on 3.62 acres. A long approach reveals a stately brick-and-stucco facade framed by mature landscaping, elegant up-lighting, and a gentle brook enhancing the serene setting. Inside, a grand two-story foyer with sweeping staircase introduces a thoughtfully designed layout. The main level offers seamless flow for everyday living and entertaining, featuring a sunlit dining room, oversized living room with panoramic views, and a front-to-back great room with tray ceilings, hardwood floors, custom inlays, and a gas fireplace with marble surround. The kitchen is well-appointed with a 36″ Viking range, center island, and maple cabinetry, opening to an expansive composite deck with modern cable railing, built-in gas fire table, and gas line for grilling. A first-floor bedroom with ensuite bath, plus laundry, powder room, and pantry, add flexibility. Upstairs, four bedrooms each offer ensuite baths; the primary suite includes tray ceiling, sitting area, dual walk-in closets, office/meditation room, and a spacious bath with soaking tub and walk-in shower. A full unfinished basement (~2,200 SF) with egress windows and two staircases offers endless potential. 3 Car Garage, four-zone HVAC system, 300-amp electrical service, most-of-house generator with automatic transfer switch, advanced water filtration systems and a view from every room!
