Marie Penny Special to the Daily News Editor's note: Each month this season, we will publish a column from the Preservation Foundation of Palm Beach featuring a landmarked property. Last month’s column focused on the founding of the ordinance, this month we will take a closer look at the classic example of adaptive rehabilitation: The Warden House, 200 N. Ocean Blvd., previously 112 Seminole Ave. The Warden House was designed by Addison Mizner in 1922 for William Gray Warden, a Standard Oil partner. This Mediterranean Revival estate took up an entire oceanfront block and had a U-shaped plan centered around a patio. But by the 1970s it seemed that the house was destined for the same fate as Mizner's demolished estates El Mirasol, Playa Riente, and Casa Bendita.
