109 Gulfstream ST, Marco Island, FL, 34145 | $3,970,000

This brand new coastal contemporary Marco Island custom home is move-in ready and designed to maximize water views, natural light, and luxury living. Offering over 4, 000 square feet under air, it features five bedrooms, four and a half bathrooms, a family loft, and multiple indoor and outdoor living spaces perfect for entertaining and relaxing. Step through the grand two-story foyer into the open-concept great room, both soaring 23 feet high and drawing your eye through 41 feet of sliding glass doors to breathtaking water views. The gourmet kitchen is a chef’s dream with premium Thermador appliances, a gas range, and a hidden walk-in pantry. High-end quartz countertops and plank-style flooring run throughout the home. The first floor includes a large family room, an additional living area, a master suite with a spa-inspired bath, and a second bedroom that could serve as a private office. Upstairs, the loft overlooks the great room and opens to a large covered balcony facing the water. The second floor also includes two bedrooms, two bathrooms, and a bunkroom (5th bedroom). Outdoors, the home showcases 80 feet of waterfront on a long, uninterrupted 1, 400-foot stretch of canal, providing expansive water views. The backyard includes a swimming pool with sundeck and spa, and a fully equipped outdoor kitchen. Additional highlights include a 500-gallon underground propane tank pre-wired for a generator, southeastern exposure for abundant sunlight, and a central Marco Island location within walking distance to the YMCA and near the island’s elementary and middle schools. Priced under $1, 000 per square foot as a 2025 construction, this home offers exceptional waterfront luxury and unmatched value among new homes.
