Today, The Wall Street Journal features a triplex penthouse in Hong Kong's "Lower Peak" as their House of the Day. With 4,146-square-feet of living, two-bedrooms, 2.5-bathrooms, and a sauna, the unit has casual yet sophisticated interiors and, while not too spectacular, it definitely has a sense of high-style. But the views are the true selling point: the new owner will enjoy breathtaking city and mountain panoramas from the large, picture windows and the two-private rooftop decks. So, how much does it cost to live in such an apartment? A price-per-square-foot that may make even New Yorkers do a double take (well, unless you reside at 15 Central Park West or The Plaza): $15,200,000, or $3,600-per-square-foot.
