Real Estate: The $80 Million Dome Penthouse

The "Dome Penthouse", the fabulous topfloor abode at the famed Plaza Hotel, is currently on the market for a record $80 million.

The lavish duplex, ideally situated on The Plaza's 18th and 19th floors, is owned by fashion mogul Tommy Hilfiger, who bought it back in 2008. He and his wife, Dee, spent more than $20 million on a renovation that took more than three years.

"I wanted to bring back the original vision of The Plaza to what it was during Truman Capote's Black and White Ball ... that old-world charm, with the original detail and glamour," Mr. Hilfiger said in an interview with CNBC.

Some highlights of the residence: four bedrooms and five baths, a grand staircase bathed in red carpet, a private terrace with Central Park and Fifth Avenue views and 6,000 square feet of living space.

The Plaza is a fully staged, 24-hour, luxury white glove condominium with a separate private entrance. Residents are offered the full complement of hotel services, including maid, valet and Todd English room service.
