Throughout his career, Seibert racked up accolades such as being named a fellow of the American Institute of Architects and winning the AIA Test of Time award multiple times, including his work on the MacDonald House on Siesta Key, the Cooney House on St. Armands Key and Bayport Beach and Tennis Club on Longboat Key.

The Ness House, on Sanderling Road on Siesta Key, is a landmark example of the design style referred to as the Sarasota School. Built in 1958 and renovated in 1971, the Ness House at 7647 Sanderling Road sits on nearly an acre with 135 feet of waterfront overlooking Heron Lagoon.

“The Ness House stands as a remarkable convergence of architectural heritage, contemporary elegance, and natural beauty,” says Joel Schemmel, Premier Sotheby’s International Realty, the property’s listing agent, in a statement. “This is a rare opportunity to own a piece of architectural history reimagined for modern coastal living.”

While built in the 1950s and renovated in the 1970s, the home is modern throughout and engineered with a poured concrete method developed by builder John Lambie. There are four bedrooms, three full baths and two partial baths.

The property last sold in 2014 for $1.75 million, according to county tax records. The median home sales price then was about $200,000 with the current median for the region about $470,000 for a single-family home.
