Set behind a private gate on 1.20 Acres+/- in East Hampton Northwest, 90 Oyster Shores Road is a 5,500 SF+/- modern waterfront residence completed in 2016 by architect Kevin O'Sullivan and builder Jason Klinge. Positioned directly on the bay, the home pairs open, light-filled interiors with a layered outdoor setting encompassing an infinity edge gunite pool, patios, open and covered porches, a sun deck, and direct waterfront access. The 5-bedroom program includes 4 Full and 1 Half Bathrooms, with multiple gathering spaces designed to frame the water and support both everyday living and entertaining. An entry foyer introduces the main living spaces, where hardwood flooring and water views establish a bright, composed atmosphere. The open kitchen is equipped with custom cabinetry, stone countertops, and Gaggenau appliances, opening naturally toward the living, dining, and family rooms. Three gas fireplaces add warmth throughout the residence, while the layout balances larger social spaces with more private retreats. On the upper level, the primary suite includes a Walk-in Closet, en-suite bathroom, and private rooftop balcony overlooking the waterfront setting. Additional guest accommodations are arranged throughout the home with supporting full and half bathrooms. The exterior is centered on the bayfront setting. An infinity edge gunite pool anchors the grounds, complemented by patio space, open and covered porches, a sun deck, roof terrace, and outdoor barbecue. Mooring rights, waterfront access, and beach access extend the use of the property directly to the water, while the sauna and steam room introduce a dedicated wellness component. Garage space includes an attached garage and a detached garage currently used as an office, adding flexibility to the property without interrupting the main residence. The residence is supported by forced-air and radiant heating supplied by propane, central air conditioning, Lutron lighting, Sonos sound, central vacuum, a generator, and an alarm system. Its location in East Hampton Northwest provides a more private waterfront setting within the broader East Hampton community, with the bay defining the experience from the grounds through the upper-level outdoor spaces. 90 Oyster Shores Road brings together privacy, modern design, and direct waterfront access in a setting shaped by open sky and expansive water views.
