Welcome to Island House, one of the most compelling luxury offerings in Bayway Isles II. Set within the exclusive guard-gated enclave of Bayway Isles, this extraordinary Mediterranean residence occupies an expansive homesite and offers a rare combination of scale, privacy, luxury, and lifestyle. Spanning approximately one acre-including a portion of the lake-Island House enjoys tranquil lake views, spectacular sunsets, and a remarkable sense of privacy rarely found within St. Petersburg's island communities. Bayway Isles II remains one of Tampa Bay's most coveted addresses, known for distinguished residences, larger homesites, and an atmosphere of exclusivity. Encompassing nearly 6,400 square feet of curated living space and approximately 8,500 total square feet, the home blends timeless architecture with modern refinement. Soaring 12-foot ceilings, marble flooring, solid wood doors with transoms, graceful archways, designer lighting, 2023 clay tile roof, and elegant finishes create a sense of understated grandeur throughout. The chef's kitchen showcases premium appliances, leathered imported granite, custom cabinetry, an oversized island, veggie sink, and breakfast area flowing seamlessly into the great room. Luxury amenities include a climate-controlled 160-bottle wine room, butler's pantry, whole-home Sonos audio, upgraded theater technology, and extensive recent improvements. The primary suite is a private sanctuary featuring a fireplace, morning bar, custom closets, and a spa-inspired bath with soaking tub, dual vanities, and steam shower. Two guest suites with en-suite baths are privately positioned opposite the primary wing, while a grand executive office and dedicated pool bath enhance functionality. Designed for entertaining, Island House features a true stadium-seat theater with reclining chairs and popcorn station, along with a spacious media room. Upstairs, a private one-bedroom suite includes a large bath, walk-in closet, full kitchen, and separate living area-ideal for guests, multigenerational living, or extended stays. The upper level also offers the opportunity to create an extraordinary second primary suite or private wing. Outside, the reimagined heated pool and spa feature newly installed tile, upgraded automation, lighting, equipment, and a saltwater system. A restaurant-caliber outdoor kitchen and separate outdoor bar with sink, refrigeration, and 85-inch television create an exceptional setting for sunset entertaining overlooking the lake. With 24-hour guard-gated security and convenient access to Gulf beaches, downtown St. Petersburg, marinas, and Tampa International Airport, Island House represents a rare offering where architectural presence, exceptional amenities, and resort-style living converge. Despite its stunning water views and expansive grounds, the residence has never flooded. Recently repositioned to $3,750,000, Island House now represents the least expensive estate-sized residence currently available in Bayway Isles II. Whether envisioned as a private family compound, entertainer's retreat, or multigenerational residence, Island House offers a level of privacy, scale, and resort-style living rarely found along Florida's Gulf Coast. The home may be sold fully furnished. Seller intends to review offers through the end of June while reserving the right to accept an exceptional contract prior to that time.
