On the north end of Longboat Key, where mangroves ring Sarasota Bay and the Gulf shows just beyond the tree line, a pale geometric structure sits on just under six acres of bayside land. It doesn’t introduce itself simply by address. At this tier of the market, houses acquire titles.

This one is called the House of Columns. Designed by Carl Abbott, the residence at 6610 and 6630 Gulf of Mexico Drive contains 6,891 square feet of living area under 9,740 square feet of roof. Its nearly six-acre lot may be the most important detail, though. Contiguous parcels of this scale are rare on Longboat Key, where waterfront land is typically divided, maximized and redeveloped in smaller increments.

Instead of a fanciful name like La Serenissima—the name of the $30.3 million banger that was the priciest sale in both Sarasota and Manatee counties last year—the name House of Columns is literal. A procession of thick rectangular piers lines the principal façade, lifting a long horizontal volume above the lawn. At one end, a cantilevered cube projects outward over the terrace, a controlled act of structural bravado. This is not delicate, mid-century glass-box modernism. The columns are substantial. The shadows are deep. It all reads as composed and deliberate, even a little austere.

Abbott, long associated with the Sarasota School of Architecture, has consistently worked with climate and light as organizing principles. Here, double-height window bays frame eastern exposure across the bay. Deep reveals temper glare. Interior volumes align with horizon and water. At dusk, the façade becomes a vertical lantern, its rhythm doubled in the curved pool below.

The Sarasota School of Architecture is a mid-century regional modernist movement that helped define the Gulf Coast’s architectural identity. Emerging in the 1940s and 1950s through figures such as Paul Rudolph, Ralph Twitchell and Victor Lundy, the Sarasota School adapted International Style modernism to Florida’s climate. The goal was environmental intelligence.

Abbott, who began practicing in Sarasota in the 1960s, entered the movement’s second generation. His work retained the Sarasota School's emphasis on light and structure, but often expanded in scale and sculpture. Where early Sarasota School houses could feel almost delicate, Abbott’s later residential projects often carry more weight—thicker piers, deeper shadow lines, more massing—while still prioritizing orientation to water and sky.

The House of Columns reflects that lineage. The pool traces an arc along the base of the columns, softening the geometry without undermining it. Beyond, a stepped lawn terraces toward a private dock with two lifts and access to Sarasota Bay. Mangroves buffer the shoreline, reinforcing privacy and protection. 

Inside, the architecture is disciplined: pale wood floors, 21-foot ceilings and lots of glass. The double-height living space is impressive but not theatrical. The structural grid outside continues inward, giving the house coherence.

According to property records, the home was built in 2007. The kitchen, with flat-panel maple cabinetry and frosted glass uppers, feels early-2000s contemporary. The long horizontal window is strong; the proportions are clean. Yet the material palette situates the room in a specific design moment.

The primary bath follows suit: floating wood vanities, glass vessel sinks, a wall of warm-veined stone beneath exposed lights. It is cohesive and high-end and, again, of its era. In a market where many homes are aggressively updated to match current luxury trends, there is something almost defiant about interiors that have not been cosmetically reworked every five years.

But architecture is more timeless than the cabinetry. Structure outlasts fashion.

Ownership records indicate the property has been held in a revocable trust since 1999, pointing to long-term stewardship rather than turnover.

For millionaires seeking alternatives on Longboat Key, options exist. Current listings include a 9,243-square-foot bayfront home on Juan Anasco Drive at $22.75 million, Gulf-front and bayside estates along Gulf of Mexico Drive in the $13.9 million to $15.55 million range, and new construction on Gulfside Road priced around $15 million. Those properties offer more interior square footage in some cases, newer finishes in others, and direct Gulf frontage in a few.

What they don't offer is 5.74 acres under a single residential designation with an intact, late-career Carl Abbott design.

The House of Columns delivers on the columns. It delivers on the land. It delivers on scale. Whether it needs a title is debatable. But in a market where houses compete not just on views and finishes but on identity, it has one. That, too, is part of the offering.
