An Upper East Side mansion whose stark limestone facade is a foil for six levels of elaborate interiors that take their cues from disparate locales like the Palace of Versailles, the historic castles and churches of Italy, and a red velvet movie theater that once thrived in Queens, is poised to enter the market at a genre-popping asking price of $114.077 million.

The annual $178,246 property tax covers 20,000 square feet of living space and 2,500 square feet of outdoor options crowned by a three-tier roof deck with glimpses of Central Park and the cityscape. This sprawling urban fortress, built in 1883, has a service entrance tucked beneath the elegant stone steps of the formal entry, an indoor heated saltwater pool with spa, and a “panic room”/dressing room off the fifth-floor master suite hard-wired for total security.

The house, at 12 East 69th Street, between Fifth and Madison Avenues, has seven bedrooms, six baths and three powder rooms. Its rare width, 40 feet, guarantees mansion status, even though its limestone facade was stripped of ornamentation in the 20th century, when its usage changed to accommodate a suite of medical offices.

After Teresa Viola, the president of Maida Vale Designs, found out the building she frequently visited with her three sons — to consult their pediatrician — was for sale, she didn’t resist the temptation to transform it into a private palace whose ceiling heights range from 12 to 34 feet.
