The Bluffs at Premium Point represents a once-in-a-generation opportunity to acquire one of the most significant waterfront estates on Long Island Sound in the award-winning Mamaroneck school district. Set on 1.3 acres at the crest of Premium Point’s coveted 24-hour guard-gated peninsula, this newly completed residence commands extraordinary 360-degree views across the Sound and Premium Mill Pond. One of the enclave’s landmark “Big Four” properties, it offers an irreplaceable combination of scale, privacy, elevation, water frontage and proximity to Manhattan. Built by Cum Laude Group, one of Westchester’s premier luxury builders, the residence reflects an uncompromising commitment to craftsmanship, materials and execution. Portions of the original stone estate remain within its footprint, while a new slate roof, copper gutters, and entirely new systems, finishes and surfaces bring modern refinement and full builder warranty. More than 13,000 square feet of beautifully finished living space unfolds across multiple elevator-served levels, with eight bedrooms, 10 full and three half baths, a heated and cooled three-car garage, pool house/guest suite and dedicated fitness level. Walls of glass, expansive Marvin windows, high ceilings, white oak floors, sculptural stairways and custom millwork frame sweeping water views from nearly every principal room. The main level is anchored by a dual-island chef’s kitchen with custom white oak cabinetry, dramatic marble surfaces, Wolf and Sub-Zero appliances, two Bosch dishwashers, extensive pantry storage and a sunlit breakfast bay overlooking the Sound. A separate butler’s pantry with wine refrigeration connects to the formal dining room, while the living and family rooms open through multiple sets of glass doors to expansive bluestone terraces and uninterrupted water views. The primary suite is a private retreat with panoramic Sound views, gas fireplace, two boutique-scale walk-in closets and a spa bath with steam shower, freestanding tub, and marble finishes. Additional ensuite bedrooms, a flexible office/guest suite, second-floor laundry, third-floor recreation room and private guest accommodations provide exceptional versatility for entertaining and extended stays. Outdoors, professionally landscaped architecture, a Belgian-block motor court, broad waterfront terraces, pool and spa, private neighborhood beach access, boat slips and a covered outdoor kitchen with Lynx appliances create a complete setting for waterfront living. The separate two-story pool house adds a guest suite, pool bath, dedicated laundry and dramatic custom gym. Infrastructure is equally impressive, including seven-zone high-efficiency HVAC, radiant heat in select areas, Lutron RadioRA 3 lighting, Sonos audio, commercial-grade network/WiFi, 400-amp electrical service, upgraded water and gas service, fire sprinklers, and whole-house generator. Rarely does an offering combine this caliber of construction, architectural finish, waterfront presence and privacy within a short commute to New York City. The collaboration of an irreplaceable Premium Point setting with the craftsmanship of Cum Laude Group elevates The Bluffs beyond even the exceptional. It is a legacy property in one of Westchester’s most tightly held enclaves, created for a buyer who recognizes that true luxury is ultimately defined by what cannot be duplicated. For those with the ability to choose among the finest homes in the world, this is the kind of property that stands apart not simply for its quality, but because opportunities of this caliber on this setting are seldom available at any price.
