The Life -- and Death -- of London and New York

Towers of Secrecy, a New York Times series, examined the shady characters behind the shell companies that own condos in the ritzy Time Warner Center. This DnA broadcast looks at another aspect of global investment in residential property: the urban impact. How does it affect local business? Why is the trend being called “zombie urbanism?”

DnA talks to Peter Zellner, Principal at AECOM's Los Angeles design studio, Deyan Sudjic, Director of the Design Museum in London, Matthew Lasner, author of High Life: Condo Living in the Suburban Century, and Michael Kwartler, founding President of the Environmental Simulation Center about how this is playing out in New York and London.
