About This Home
Never before seen, On The Break is a rare compilation of new construction luxury homes set amidst the natural landscape and vibrant cultural scene of Montauk. Encompassing two separate oceanfront lots, the enclave presents an unmatched opportunity to own in the highly sought after Ditch Plains area. One of the most iconic surf destinations on the East Coast, the break within Ditch Plains boasts powerful waves that attract surfers all year round. A captivating locale due to this foremost surf break, Montauk provides a truly unparalleled setting for creativity, community, and oceanfront living within this exclusive enclave. Set on a sprawling 1 +/- acre parcel with an impressive 95 feet of direct ocean frontage, Casa Las Olas stands as the quintessence of opulent coastal living. Recently unveiled, this newly constructed residence encompasses 4,800 +/- sq. ft. of refined living space. Crafted with visionary brilliance by renowned architect Boris Baranovich, every facet of the design harmoniously accentuates unparalleled ocean views that grace nearly every vantage point within the six-bedroom home. A grand double-height entry foyer sets the tone for the interior, which has been partially staged with luxury furnishings curated by Meredith Baer. An ode to open concept living, the main level seamlessly blends two sitting areas, formal dining, and a fully-equipped kitchen which incorporates top-tier appliances, an inviting island with ample seating, and a separate pantry. The three-car attached garage is ideally situated towards the front of the property, with direct access to the laundry and mudroom. Positioned on the second level, the spacious primary suite features a fireplace with sitting area, steam shower, multiple closets, and a private waterside terrace. Four additional bedrooms complete this floor. Accessed via glass doors along the main living area, an expansive deck spans almost the entire width of the home. With ample room for entertaining, the exterior affords outdoor dining, a covered sitting area, and an oceanside heated 20' x 30' gunite pool with sun shelf and spa. Meticulous landscaping by Terra Designs exudes an aura of natural elegance while ensuring total privacy within the property.
