154 Oakview B Highway Commanding 4.1 pristine acres in East Hampton, The Oakview Reserve is a rare contemporary estate defined by architectural precision, natural beauty, and exacting attention to detail. Substantial yet effortless, the residence balances enduring Hamptons character with the clarity of modern design. Its future owner may refine select finishes while preserving the integrity of its architectural vision. Positioned with sensitivity to its natural surroundings, the home is oriented to embrace the exposure throughout the day, allowing natural light to become a defining architectural feature. Expansive Marvin windows and doors frame the landscape, creating a luminous connection between indoors and out. Arrival is quietly dramatic. A custom pivot door opens to a soaring 23.5-foot double-height foyer, where volume, light, and sculptural form establish an immediate sense of space. A custom floating staircase ascends with visual lightness, while a private elevator provides effortless access across all three levels. Bespoke millwork distinguishes the great room, joined by an integrated beverage center, custom fireplace detailing, and a covered terrace for fluid indoor-outdoor living. Smart home integration adds intuitive ease throughout. At the heart of the residence, the kitchen pairs Sub-Zero and Wolf appliances with a dramatic waterfall island featuring hidden outlets and a fully outfitted butler's pantry designed for both everyday living and large-scale entertaining. Two primary suites offer exceptional flexibility and privacy. The main-level primary opens directly to the grounds and features a fireplace, custom built-in closets, and a spa-inspired bath with steam shower and dual vanities. Above, a junior primary retreat offers its own fireplace, refined ensuite bath, and private wraparound terrace overlooking the landscaped property. Wellness is woven naturally into daily life. Radiant heated floors extend through every bath, while a dedicated fitness studio is complemented by a steam shower, dual vanities, full bath, and space for a future integrated spa or cold plunge. The lower level is remarkable in both volume and possibility. Soaring 10-foot ceilings and polished concrete floors create the atmosphere of a private destination, with the option to incorporate radiant heat. A recreation lounge, climate-controlled wine storage, intimate tasting area, and optional eSommelier technology extend the entertaining experience, while provisions for a future theater, golf simulator, or private bowling alley allow the space to evolve around the owner's lifestyle. Outside, a 20-by-50-foot heated Gunite pool with integrated spa anchors the grounds, surrounded by Luxe Blue pavers. A custom outdoor shower, separate pool house, and fully appointed outdoor kitchen with Sub-Zero and Wolf appliances and a beverage center extend the living experience into the landscape. With approximately 35 percent clearing, the property offers opportunity for a future tennis, pickleball, or basketball court, while an optional recessed fireside lounge creates an intimate setting to gather, unwind, and welcome the settling of the evening. Less than two miles from East Hampton Village, The Oakview Reserve offers rare seclusion within easy reach of Main Beach, Newtown Lane, Guild Hall, LongHouse Reserve, celebrated dining, galleries, and the cultural life that defines the area. The true distinction of The Oakview Reserve finds its grace in the gatherings, in long summer brunches buoyed by bubbles of conversation, lingering evenings filled with occasion, and the quiet rise of light-filled mornings ahead. The residence settles naturally into the familiar fabric of the Hamptons, gathering meaning with each passing season and gradually becoming part of the legacy it was destined to define. An immersive 3D tour is available to experience the residence's scale, flow, and architectural vision.
