As the city that inspired Zaha Hadid mentor Rem Koolhaas to write ‘Delirious New York’, a manifesto for deconstructivism in all but name, it’s strange to think that the late Hadid never put up a building in the Big Apple – until now. At 520 West 28th in West Chelsea – 39 condos over 11 storeys – New Yorkers, especially those on the adjacent High Line, can finally sample the parametric work of the Pritzker, Stirling and Royal Gold Medal winning architect. Top of the shop is Penthouse 37, a 647m2, five-bedroom, triple level affair with 3.7m ceiling heights, sculpted staircase, 200m2 terrace and two private balconies. Yours at a snip for $50million.
