Tuesday 15 April 2008, 19.00–20.30

Renzo Piano introduces The New York Times Building, the 52-storey glass skyscraper housing the new headquarters of the newspaper. In contrast to the usual Manhattan office building, clad in mirrored or tinted glass, Piano's elegant structure is clear glass. Sited in Times Square, the building invites interaction with the street: its lobby forms a public walkway between streets, and internal staircases flow along the side facades, allowing passers-by a view inside.

When the Starr Auditorium is sold out, tickets at £4 each will be available for a Live Video Relay of the event in the Seminar Room. Ticket holders for the Seminar Room will watch the event on a screen, and will not be able to participate in the Q&A at the end of the talk. A complimentary glass of wine will be served to viewers in the Seminar Room.
