Welcome to 821 Peconic Street — an oversized, custom ranch in the highly desirable Connetquot School District offering the perfect blend of craftsmanship, luxury, space, and modern convenience. From the moment you enter, you’re greeted by a stunning open floor plan with vaulted ceilings, custom millwork, oak beams, rich wood flooring, and a gorgeous stone wood-burning fireplace that anchors the main living space. The custom-designed kitchen features cherry wood cabinetry, granite countertops, stainless steel appliances, vaulted ceilings, tile flooring, and sliding glass doors leading out to a private paver patio, perfect for relaxing outdoors. The formal dining room is equally impressive, complete with tray ceilings, inset lighting, and an elegant flow into the main living area. The home ’s grand primary suite is truly one of the largest on the market, featuring vaulted ceilings, two massive walk-in closets, and a spa-inspired marble bathroom with radiant heat, sunken jetted tub, separate shower, and double vanity. Three additional queen-size bedrooms, a beautifully appointed family bath, a full stand-up attic, central air, owned solar panels, and a brand-new driveway add even more value and convenience. The fully renovated basement takes this home to another level, offering radiant floors, a gas fireplace, a gorgeously updated full bathroom, a full-service wet bar with quartz countertops, and an additional guest room, office, or flex space — ideal for extended living, entertaining, or working from home. With radiant flooring throughout the entire home, including the basement, owned solar panels, custom details throughout, and a mint-condition interior, this is not your average ranch. Spacious, elegant, and loaded with upgrades. This is the one you have been waiting for!
