About This Property

Experience unparalleled coastal luxury in this stunning Island Estates residence perfectly positioned on a ¼-acre lot with 180° unobstructed open-water views. This exquisite home offers 4 bedrooms plus an office, 3.5 baths, and a 3-car garage, seamlessly blending elegant design with state-of-the-art functionality. Boaters will delight in the deep-water dock featuring two lifts (including a 16,000 lb lift), shore power for larger vessels, and easy Gulf access for endless days on the water. The outdoor oasis is a true showpiece-complete with a heated saltwater pool and spa, waterfalls, fire bowls, and custom lighting, all framed by tranquil water views. Enjoy sunset cocktails or waterside dining beneath the charming gazebo, surrounded by lush tropical landscaping and added protection from the riprap seawall. Step inside through custom double doors to discover sophisticated living spaces, including a formal sitting room with a grand gas fireplace and sweeping views through custom French doors. The chef's kitchen is equipped with high-end stainless steel appliances, a gas range, and overlooks the spacious living area with dual 4-panel sliders that open wide for seamless indoor/outdoor living. The owner's retreat is a private sanctuary on the main level, featuring double-door entry, a Venetian-inspired en-suite bath with soaking tub, walk-in shower, and his-and-hers closets. Step directly outside to enjoy morning coffee by the pool as the sun rises over the water. Additional highlights include a temperature-controlled 800-bottle wine cellar, impact glass throughout, natural gas service for energy efficiency, and ample storage-including a walk-in attic and home automation system to control lighting, blinds, A/C, garage doors, surround sound, security cameras, and more. Upstairs are three guest suites, each with dedicated bath access, and an office (or fifth bedroom) with private balcony, dedicated ventilation, and air purification system-ideal as a cigar room or quiet retreat. Located on Island Estates' most desirable street, this property benefits from sidewalks, underground utilities, and a higher elevation. Enjoy the convenience of this golf cart-friendly community featuring its own grocery, shops, and dining-all just moments from Clearwater Beach and Clearwater Sound's live entertainment. This exceptional home captures the very best of luxury waterfront living-sophisticated, smart, and perfectly situated for the ultimate Florida lifestyle.
