Tour Odeon, Monaco
Price: US$400 million (S$520 million)
Floor area: 35,000 sq ft

Besides the requisite gym, sauna, private cinema, library with ebony shelves and billiard room, there will also be tables upholstered in exotic stingray leather when this five-storey penthouse is completed in spring next year. Fancy a party but relish privacy? Head upstairs via a marble staircase to the apartment’s very own nightclub with marble flooring. Don’t like the stairs but want to use the open-air infinity pool two storeys below? Use the pool slide on the premises. Finally, retreat to a master bedroom the size of two and a half tennis courts.


432 Park Avenue, New York
Price: US$95 million (S$125 million)
Floor area: 8,255 sq ft

Views that stretch from Central Park to the Atlantic Ocean and from Lower Manhattan to Connecticut – that’s what dropping this much money gets you. The penthouse, which is 390m above ground level, was snapped up early last year even before the 104-unit, 96-storey condominium tower was half completed. Reportedly the tallest residential structure in the Western Hemisphere, the 432m-tall building, which towers over the Empire State Building, will welcome its first residents early next year. Facilities include climate-controlled wine cellars, a spa and on-site restaurants.


Opus Hong Kong
Price: HK$470 million (S$78 million)
Floor area: 5,400 sq ft

Two years after completion, the penthouse has not been sold. Developer Swire Properties withdrew a sale when a recent bid fell below the asking price. CEO Martin Cubbon told the South China Morning Post: “It’s a prime asset; we’re not so concerned about when we sell it.” The 12-storey structure has 11 other units and is Asia’s first residential building by Pritzker Prize-winning architect Frank Gehry. It rests on the slopes leading to Victoria Peak and has 360-degree views of Victoria Harbour and Hong Kong’s skyline. Every apartment has a unique layout, due to the structure’s odd horizontal twist.


One Hyde Park, London
Price: £140 million (S$290 million)
Floor area: 16,000 sq ft

Its penthouse was reportedly sold to an Eastern European in May. Oligarchs like Rinat Akhmetov and Vladislav Doronin – both of whom own homes there – can feel safe here. Completed in 2011, the 13-storey, 86-unit building has bulletproof windows, panic rooms, and security personnel trained by the British Special Forces. There’s also a stainless-steel ozone pool and 24-hour room service provided by Mandarin Oriental hotel. Rolex, McLaren Automotive and the Abu Dhabi Islamic Bank have on-site retail units, too.


One57, New York
Price: US$90 million (S$118 million)
Floor area: 13,554 sq ft

Both penthouses, completed earlier this year and designed by Pritzker Prize-winning French architect Christian de Portzamparc, sit above the Park Hyatt hotel and have been sold for over US$90 million each. The highest unit occupies the 89th and 90th floors, and is 11,000 sq ft. Its owner is said to be a well-known American family. While it’s not at the top of the 95-storey building, the other penthouse is larger. It’s owned by billionaire hedge-fund manager William Ackman, whose six-bedroom unit is known as the winter-garden duplex as it has a 51-foot-wide, glass-enclosed winter garden. Amenities include yoga studios, a pet washroom and a screening and performance room.
