Affectionately known as “The Castle,” this extraordinary Snell Isle estate is a masterpiece of timeless architecture, exceptional craftsmanship, and effortless indoor-outdoor living. Designed by renowned architect Daniel Dawson, this remarkable 4-bedroom, 4-full-bath, and 1-half-bath residence encompasses 5,640 square feet of meticulously crafted living space. Constructed of cinder block on both the first and second floors, the home reflects enduring strength and superior craftsmanship. Situated on an oversized lot in one of St. Petersburg’s most renowned neighborhoods, this exceptional property is just moments from the historic Vinoy Golf Club and minutes from vibrant downtown St. Petersburg, waterfront parks, award-winning restaurants, museums, shopping, and entertainment. Rich custom walnut flooring extends throughout both levels, while the formal living and dining rooms showcase an exquisite chevron pattern. Historic Augusta Block flooring enhances the mudroom and powder baths, and custom Allikriste cabinetry is featured throughout the residence. Designed for entertaining and everyday living, expansive gathering spaces flow seamlessly to the outdoor living areas through multiple walkouts to the patio. A magnificent main staircase, gracefully rising within the home’s iconic front turret, serves as an architectural centerpiece, while a spiral staircase tucked within the mudroom provides convenient secondary access to the second floor. The chef’s kitchen features an oversized center island, custom Allikriste cabinetry, a professional-grade Wolf range, built-in beverage drawers, and abundant prep space. Outside, the resort-inspired entertaining areas include a fully equipped outdoor grilling area, multiple covered seating spaces, and an inviting outdoor living room with a gas fireplace. Distinctive indoor and outdoor wood-burning fireplaces can be enjoyed independently or simultaneously, creating a seamless connection between the home’s interior and exterior living spaces. The beach-entry pool enhances the resort-style setting, while lush landscaping and a charming butterfly garden create exceptional curb appeal. The primary suite offers a spa-inspired bath with a steam shower, and a whole-home Generac generator provides added peace of mind. Recognized for its exceptional design and craftsmanship, the home received the DaVinci Masterpiece Contractor Project of the Year Award in 2023 for its remarkable roof installation and has also earned the City of St. Petersburg Landscaping Award. From its iconic castle-inspired architecture to its exceptional finishes and award-winning design, “The Castle” offers a rare opportunity to own one of Snell Isle’s most distinctive luxury residences.
