Palm Beach’s Landmark ‘Ham and Cheese House’ Is Listed for an Eye-Watering $105 Million
Sep
A historic waterfront estate, known as the “Ham and Cheese House” for its alternating brick and coquina stone designed by Maurice Fatio, has just hit the market in Palm Beach, FL, for an astonishing $105 million.
Built in 1927 for businessman Mortimer L. Schiff and his wife, Adele, the seven-bedroom megamansion is known as Casa Eleda, “a nod to Adele’s name spelled in reverse.”
Unbelievable amenities found throughout the Italian Romanesque mansion include a private tunnel leading to the beach, complete with an elevator, and a beachfront cabana with a living room, wet bar, and full bath.
Offering more than 150 feet of direct ocean frontage, the 13,171-square-foot seaside residence—which is said to be owned by Penny Antonini, wife of the late Marion H. Antonini, a former Xerox executive—has surfed to the top of the week’s most expensive homes list.
Historic highlights include arched windows, beamed cypress ceilings, multiple loggias, a formal living room with a coffered ceiling and marble fireplace, and a dining room with a beamed cathedral ceiling and marble fireplace.
Other amenities include a chef’s kitchen, a “striking” bar room, an oceanfront library, a water-facing primary sanctuary with dual baths and closets, a sitting room with a fireplace, and a balcony with expansive water views.
There’s also an exercise room, a home office, an elevator, a recreation room, and a wine cellar.
More spectacular estates to make the week’s most expensive homes list include a New York mansion overlooking Mecox Bay, the Grand Penthouse at the St. Regis Residences overlooking Boston‘s Seaport District, and a brand-new mountain retreat in Aspen, CO.
