About this home

Welcome to 550 Madison Avenue in Greenport, a thoughtfully designed New Construction farmhouse that feels comfortable from the moment you arrive. The covered front porch is more than an architectural detail. There is actually room for a chair and side table, creating the perfect spot for a quiet morning coffee. Inside, wide 6-inch oak floors connect the bright, open living spaces. The powder room is conveniently located near the front entrance, but it is tucked far enough away from the open living room, dining area, and kitchen to give everyone a little privacy when the house is full. The custom kitchen design brings together the features buyers keep asking for, including a paneled refrigerator, a full pantry closet, open shelving, generous cabinetry, and a kitchen sink positioned beneath a window overlooking the backyard. Even doing the dishes comes with a view of the established maple trees. A full glass slider in the dining area fills the back of the home with natural light and creates an easy connection to the outdoor entertaining spaces and grill. The backyard views can also be enjoyed from the living room, making the surrounding landscape feel like part of the interior design. Upstairs, the primary bedroom features a peaceful en-suite bathroom with distinctive tile flooring and calm, carefully selected finishes. Even the first-floor powder room has beautiful wallpaper, adding personality and making this New Construction home feel intentional rather than predictable. The fully fenced backyard is surrounded by established maple trees, creating a quiet and private setting that feels like a hidden corner of Greenport. The newly installed stone patio includes an outdoor cushioned conversation area, a separate outdoor dining patio, and a dedicated fire pit for evenings under the trees. There is also room to explore the possibility of adding a pool without making the yard feel crowded. The location brings the North Fork lifestyle within easy reach. The Greenport LIRR station and Hampton Jitney stop are approximately half a mile away for convenient transportation to New York City. Aldo’s Coffee is about a three-minute bike ride or a ten-minute walk, with Greenport Village shops, restaurants, waterfront destinations, and local beaches all close enough to enjoy without always getting back into the car. New Construction, a custom kitchen, paneled appliances, wide oak floors, en-suite bathrooms, a fenced backyard, mature trees, outdoor entertaining spaces, and easy access to Greenport Village. This might be the one you have been waiting for. You really need to come see it. In the evening it sparks with fireflies to capture summer vibes in Greenport Village.
