Skyscrapers today are controversial – especially in New York – but globally they are getting taller and more numerous. This evening features two authors, an economist, Jason M. Barr, and a real estate reporter, Katherine Clarke, discussing their recent books on supertall skyscrapers. The program, which is organized by the Council on Tall Buildings and Urban Habitat (CTBUH), New York Chapter, will be moderated by Peyman Askari, founding principal of PAN Partners and the CTBUH New York Chapter Executive/Co-Chair.
