Warm Mineral Springs Motel is a historic 1958 motel designed by Victor Lundy, a member of the Sarasota School of Architecture. It is listed on the National Register of Historic Places. The motel is known for its mushroom Champagne glass style roof and glass walls, allowing guests to see the stars. It was originally built as an "L" shape. With just 20 units at that time, it was ultra modern in design. There was an open house on March 19th, 1958 and the Inn had an estimated 10,000 visitors at the grand ceremony. The owners at that time were a couple from Venice, FL. Many of Lundy's works incorporated graceful curves and soaring roof lines. A signature style of Lundy's was "more roof than wall". The motel was selected by the American Institute of Architects for the 1958 Special Awards.
Lundy wrote in a 1958 issue of The Florida Association of Architects: "I was searching for a form that would somehow symbolize the thought of the Fountain of Youth by a plastic flowing shape, that would also echo the organic growing shape of a tree. The answer came in the adoption of a structural system based on using precast concrete hyperbolic paraboloids, 14-15 foot square (from basic motel unit width-requirement, plus necessary overlap) in two heights arranged in a U-shaped plan (the remaining wing will be added shortly). Three of the so called shells were lifted up on higher columns of varying height to form the sign of the motel, as a free-standing piece of sculpture."
The reception desk is original (from 1958). The pool area was added in 1990.
