Welcome to a home where intention and elegance meet - a custom-built 4-bedroom, 3-bathroom sanctuary set on nearly half an acre in the quiet, sought-after community of Winthrop Harbor. Built just 15 years ago by its original owner-a respected builder who designed it for his own family-this residence is a rare fusion of structural integrity, thoughtful detail, and understated luxury. From the moment you arrive, the curb appeal speaks volumes: stately brick and stone exterior, mature landscaping, and a generous driveway leading to an oversized 2.5-car garage. Step inside and you're greeted by newly refinished hardwood floors that extend throughout the main level, where natural light pours through expansive windows and vaulted ceilings create a sense of airiness and ease. The open-concept floorplan flows effortlessly-from the welcoming foyer to the gracious living room and into the heart of the home: a chef-inspired kitchen adorned with rich granite countertops, stainless steel appliances, custom cabinetry, and an oversized island perfect for casual dining or morning coffee. Whether you're hosting a holiday dinner or a quiet evening in, this home adapts with style and grace. The primary suite is a private retreat, complete with tray ceilings, a large walk-in closet, and a spa-style en-suite bath featuring a whirlpool tub, double vanities, and a frameless glass shower. Two additional main-floor bedrooms offer versatility for guests, kids, or a dedicated home office. Downstairs, a beautifully finished lower level expands your living space dramatically, offering a sprawling family room ideal for movie nights, a spacious fourth bedroom with full egress, and nearly 1,000 sq ft of open space awaiting your vision. Already stubbed for an additional full bathroom, this area is a blank canvas-perfect for a gym, studio, guest suite, or even a home theater. Step outside and find yourself surrounded by quiet tranquility. The backyard is partially fenced, with open green space that invites outdoor entertaining, gardening, or simply stargazing on summer nights. There's ample room for a pool, a playset, or even an outdoor kitchen if desired. But what truly sets this home apart is the rare combination of craftsmanship and setting. Union Grove charm meets Lake Michigan living in a community known for its peace and pride of ownership. You're minutes from the harbor, walking trails, marinas, and local dining-but also enjoy easy access to IL Route 173, Metra, and nearby highways for seamless commuting to Chicago or Milwaukee. Homes of this caliber, size, and construction rarely become available-especially ones that feel as move-in ready and emotionally resonant as this. Every inch tells a story of quality, care, and comfort. Whether you're looking to upsize, relocate, or invest in a lifestyle of thoughtful living, 1340 Park Avenue offers an opportunity few homes can match.
