One of the true pleasures of city life is to get above it all, to view the skyline and the streetscape from a high vantage—not off the grid, but above it. Luxury Defined rises to those heights with its collection of blue-sky penthouse dwellings in cities across the globe. Start in New York, in a dazzling duplex atop the iconic Bloomberg Tower; then to Bangkok, and a top-floor residence above the River of Kings; to St. Petersburg, Florida, where a designer duplex faces Tampa Bay; to Prague, and a sleek ultramodern triplex in the V Tower skyscraper; to Aspen, and a penthouse with vistas of the Rockies; and then to Sydney, where penthouse views of the Harbour Bridge and Opera House grace its terraces. This truly is life at the top, waiting to be lived.
