The World's Most Expensive Apartments in 2026

The global market for ultra-prime residential real estate has never been more concentrated at the very top. The ten most expensive apartment buildings in the world account for a disproportionate share of all transactions above $50 million — and the addresses that make that list are consistent year after year.

220 Central Park South, New York

Ken Griffin's $238 million purchase here set a US record that has not been broken. The building, designed by Robert A.M. Stern, sits at the southern edge of Central Park with views that are genuinely irreplaceable. The architecture is deliberately classical — limestone facade, traditional proportions — in deliberate contrast to the glass towers that surround it. Full-floor residences start at around 6,000 square feet. The building has its own wine cellar, private dining room, and a level of service that rivals the finest hotels. The waiting list for the handful of units that come to market is long and discreet.

The Odeon Tower, Monaco

The Odeon Tower's Sky Penthouse is five floors of the most extraordinary residential space in Europe. A private pool, panoramic views across the Mediterranean, and an address in a principality with zero income tax. The penthouse was listed at €300 million and represents the most ambitious residential offering in Monaco's history. The building's lower floors — still priced above €40,000 per square metre — offer a more accessible entry point to the tower's extraordinary address.

One Hyde Park, London

Candy & Candy's masterwork in Knightsbridge remains the benchmark for ultra-luxury London living. CCTV throughout, panic rooms standard, private underground car park, Mandarin Oriental hotel services on call. The most expensive sale exceeded £170 million. The Knightsbridge address — within walking distance of Harrods, Hyde Park, and the finest shops on Sloane Street — remains one of the most sought-after in the world.

432 Park Avenue, New York

The slimmest skyscraper in the world when completed. Full-floor residences with unobstructed views in every direction from a perch above Midtown Manhattan. The building has faced documented issues with mechanical systems — a reminder that buying at the very top of a new building carries risks that established addresses do not. At full resolution, however, the view from the upper floors on a clear day is one of the great urban spectacles on earth.

What separates these from merely expensive apartments

The common thread is irreplaceability. Each of these addresses offers something that cannot be replicated — a view, a location, a level of security and service — that makes the price somewhat abstract. For buyers at this level, the question is not whether to buy but which trophy best fits their collection. The secondary market for these addresses is thin precisely because owners rarely sell. When they do, the transactions happen quietly, off-market, through relationships rather than listings.
