Palm Beach mansion, Villa Flora, was built in 1923 for Edward Shearson. It stands at 110 Dunbar Road. La Querida ("the dear one"), apocryphally conflated with La Guerida ("bounty of war"), was built in Palm Beach in 1923 for Rodman Wanamaker of Philadelphia, heir to the Wanamaker's department store fortune. It was later purchased by Joseph Kennedy in 1933 during the depths of the Great Depression for $120,000, and eventually would become President John F. Kennedy's "Winter White House". It sold for $70,000,000 in June 2020. It stands at 1095 N. Ocean Boulevard. As early as 1925, Mizner was commissioned by Dr and Mrs (Lillian) Thomas Dempsey to build a beautiful, diminutive Mediterranean Revival summer home (possibly the smallest structure Mizner ever built). The house has 22' ceilings, enabling the architect to install a "mezzanine-loggia," encircled by the hand-wrought iron railings for which a classic Mizner building is known. The house, at 100 S. Osborne Avenue, Margate, New Jersey (formerly 8704 Atlantic Ave) is on a beach block corner where Atlantic Ave intersects Osborne. (A stone's throw away, another architectural landmark, known as Lucy the Elephant, holds court at the corner of Atlantic and Washington Avenues.) Jeff Rosen of Spielberg Productions, who purchased the home from the Dempsey estate, later sold it to Marsha & Michael Birnbaum of Bryn Mawr, Pennsylvania. It has since been purchased and is occupied by auteur-singer-poet Silkë Berlinn. Mizner's own Palm Beach home was built in 1925. It was called El Solano after the hot, oppressive wind which blows off the Mediterranean Sea in eastern Spain, but also for Solano County, California, his birthplace. Sold to Harold Vanderbilt, the estate was later purchased by John Lennon. It stands at 720 S. Ocean Boulevard. He designed and built the Riverside Baptist Church in Jacksonville, completed in 1926. Because he promised to build it in honor of his mother, Ella Watson Mizner, the architect refused payment for his services. The church stands at 2650 Park Street, and is Mizner's only work of religious architecture. The clubhouse for the Wee Burn Country Club in Darien, Connecticut was designed by Mizner in his Mediterranean style in 1926. A mansion of , with a guest house, was built at 1820 S. Ocean Blvd. for Paul Moore Sr. (completed 1926). After a two-year renovation-and-restoration project, the property was listed for sale in 2018 for $58,000,000. In 1928, he designed the original
