About this home

Tremendous Price Improvement! Perched above the coastline with sweeping views of the Long Island Sound and Mount Sinai Harbor, 5 Dock Court is a warm and inviting Contemporary designed to embrace its remarkable setting. Water views unfold from nearly every room, creating an ever-changing backdrop of passing boats, coastal skies, sunrises, and sunsets. Inside, hardwood floors extend throughout the main and second levels, while a double-sided fireplace connects the formal living and dining spaces with warmth and architectural interest. Generous windows invite natural light and coastal breezes throughout the home, and the balconies offer a peaceful vantage point for taking in the view, watching boats enter and leave the harbor, or listening to seasonal music drifting across from Cedar Beach. With four bedrooms and three and a half baths, the home offers both privacy and flexibility. The lower level expands the living space with a full bath, fireplace, separate outdoor entrance, and room for guests, recreation, work, or extended stays. Set on 1.39 private acres, the home is tucked away on a quiet court while remaining ideally situated between Port Jefferson Village and Mount Sinai. Dining, shopping, Port Jefferson Country Club, Stony Brook University, and three area hospitals are all within easy reach, as are some of the North Shore’s most beautiful waterfront destinations, including Cedar Beach and McAllister County Park. The nearby Port Jefferson ferry makes a weekend escape to New England effortless. A distinctive coastal home where the views become part of daily life.
