A Longboat Key estate that hit the market this week is Sarasota County’s most expensive listing ever, the listing agent says.
Located behind the gates of the Longboat Key Club, the property — known as Serenissima, which means “the most serene” in Italian — features 19,300 square feet of living space overlooking the Gulf of Mexico. The house has six bedrooms, six full bathrooms and two half-baths as well as a 12-car garage.
Among the highlights are a marble hall with a glass dome, grand salon that can accommodate 100 guests, Venetian murals, a 10-seat home theater, chef's kitchen and sun room overlooking the infinity-edge pool. The property also contains 145 feet of beach frontage.
Built in 2005, the home at 845 Longboat Club Road last sold in 2020 for $16.5 million. At the time, it was the highest registered residential purchase ever in the tri-county region of Sarasota, Manatee and Charlotte counties, the Business Observer previously reported.
The owner of the estate is 845 LBCR Land Trust, according to Sarasota County property records. A.K.R. Sunderlin, the trustee of 845 LBCR Land Trust Agreement, took out a $10 million mortgage on the property in 2021 along with James and Laura Rogers, county records show.
The $35 million listing price marks a new milestone for Sarasota and Manatee counties, according to Realtor Rich Polese, founder of Compass Sarasota, who is the agent for the property.
“I am honored to represent the area's most expensive listing ever,” Polese says in an email to the Business Observer.
In the past few years, the Sarasota market has seen a handful of properties approach this price point:
In the first week that 845 Longboat Club Road has been on the market, “There has been significant interest in the property,” Polese says, “with several showings having already occurred. It's going to be great for the entire Sarasota real estate market to get this amazing property sold.”
Compass, which reported more than $231 billion in sales in 2024, is the largest independent brokerage in the country by sales volume. It has more than 37,000 agents nationwide and provides access to international partners, according to Polese.
“This has afforded us tremendous reach to agents coming from all of our feeder markets both domestically and internationally,” Polese says, in marketing the Longboat Key estate. “A house of this magnitude requires and deserves a tailored marketing approach using all channels locally, nationwide and internationally.”
