Set just moments from Rye Town Park and Beach, 100 Dearborn Avenue is a beautifully appointed modern Colonial offering nearly 5,000 square feet of refined living across three thoughtfully designed levels. Built in 2020 and enhanced with numerous custom upgrades, the home seamlessly blends sophisticated design with effortless everyday living. Inside, nine-foot ceilings on every level, expansive windows that flood the home with natural light, custom millwork, and a high-end Lutron lighting system create a polished and inviting atmosphere throughout. The main level offers elegant yet comfortable living spaces, including a formal living room with gas fireplace, a dining room with custom glass-front cabinetry, and a beautifully designed chef's kitchen that opens seamlessly to a living room, creating an ideal setting for both entertaining and everyday life. A private home office and a well-appointed mudroom with built-in storage, located just off the two-car garage, add thoughtful functionality. The second level features five en-suite bedrooms, each with custom closet systems. The primary suite serves as a serene retreat, highlighted by seasonal water views, a fully customized walk-in closet, and a spa-inspired bath with radiant heated floors, soaking tub, and double vanity. The finished lower level offers exceptional versatility, featuring a spacious living area perfect for movie night, a large recreation area with built in desk, a dedicated gym with floor to ceiling mirrors, a kitchenette with refrigerator for effortless entertaining, two large walk-in closets for extra storage, and a climate-controlled walk-in wine cellar. An additional bedroom suite with attached bath on this level provides ideal accommodations for guests or extended living. Outdoor living is equally impressive. Enjoy summer fireworks from the bluestone front porch, or entertain year-round in the private backyard, complete with an expansive bluestone patio, a fully equipped outdoor kitchen, and a built-in gas fire pit. Professionally designed landscaping and custom exterior lighting create a setting that is both private and inviting.
