Dare to dream with your eyes open. That's just what renowned artist Betty Altman did when she designed and built a masterpiece she called "Castle by the Sea". Through years of inspiration, countless architectural renderings and a clear, powerful vision, this dream emerged from the white sands of Casey Key. Extensive use of floor to ceiling windows and glass doors create a larger than life frame that can only begin to capture endless views of the Gulf of Mexico. These "snapshots" of time through the lens of this home have an ethereal quality blurring the lines that separate the indoors from outdoors-and with it a certain feeling of freedom to experience the wonder of the moment. Other unique features include a porte-cochere with a circular drive leading to a grand double door courtyard entry; marble flooring; grand 2 story living room on the ground floor with a wet bar and sliding glass doors to the spacious deck and back yard; butler's pantry; private elevator; 4 bedrooms, each with a bathroom, walk-in closet and balcony overlooking the Gulf; office/library; 1200SF 3rd floor sun deck; 4th floor observation deck with 360° views; Swedish sauna & full pool bath adjoining a 75' INDOOR lap pool & hot tub for year round fitness. Also notable: Scenes from the movie "Free Ride" starring Anna Paquin were filmed here. Come experience the sand between your toes, the joy of splashing around in the warm Gulf waters, the small town feel of Casey Key & all Sarasota has to offer. Come see why this house feels like home.
