Named the House of Columns by world-renowned, award-winning architect Carl Abbott, this palatial Bayfront estate stands as a singular expression of architectural distinction and craftsmanship. Encompassing close to five acres on the north end of Longboat Key spanning Sarasota Bay, the combined offering of 6610 and 6630 Gulf of Mexico Drive represents one of the most significant residential holdings available in the area, a legacy estate where endless views of sea and sky create an unforgettable backdrop for living. The property unfolds like a private peninsula, offering exceptional width, depth and privacy. On the eastern shoreline, calm bay waters reflect the morning light with open water, protected shoreline and bridgeless access to the Gulf of Mexico. The primary residence is gracefully positioned on the bayfront, designed to capture eastern exposure and long, tranquil water views across Sarasota Bay. Clean architectural lines, soaring interior volumes, and walls of glass create a continuous dialogue between interior and exterior. Ceilings soar up to 21 feet, allowing light to move freely throughout the home while maintaining warmth and livability. The elevator provides access across levels, while Lutron lighting and automated shades on every window and door allow the home to respond intuitively to the changing light of day. The residence has been impeccably maintained by its original owner, reflecting a level of care and stewardship rarely found. Infrastructure has been thoughtfully addressed, including a whole-home generator that ensures continuity and peace of mind. The owner’s garage sits under a cantilever with access to the interior elevator and an additional air-conditioned four-car garage with large workspace offers a total space for 6 cars and exceptional flexibility for collectors, hobbies or future customization. A lagoon-style pool sits within the landscape, offering a resort-like atmosphere while preserving privacy and water views. A private dock with two boat lifts provides immediate access to Sarasota Bay and the Intracoastal Waterway, creating a seamless boating lifestyle that complements the estate’s waterfrontage. The inclusion of 6630 Gulf of Mexico Drive allows owners to construct a guest house or secondary structure, offering flexibility for multigenerational living, guests, or staff accommodations, offering extraordinary future optionality and ensures the next owner retains control over one of Longboat Key’s irreplaceable resources, land. What ultimately distinguishes this offering is its irreplaceability. Estates of this size, with this combination of architectural pedigree, boating infrastructure, development flexibility and maintained condition are no longer being created. Despite its scale and seclusion, you are moments from the refined lifestyle Longboat Key is known for, private clubs, championship golf, fine dining, IMG Academy and the cultural offerings of Anna Maria Island, St. Armands Circle and downtown Sarasota just beyond the bridge. This is not merely a waterfront home, it is a generational legacy, unmatched in design, scale, privacy and location.
