The hall’s renovation was originally going to be part of Lincoln Center’s campuswide redevelopment. There was an architectural competition, won by the British architect Norman Foster, whose redesign was approved in 2005. But the project never went anywhere, owing in part to the daunting prospect of raising $300 million in construction costs and the orchestra’s fear that it might lose audiences and revenue while it was displaced.

Now Lincoln Center, which owns and operates the hall, and the Philharmonic say they are pressing forward with renewed confidence, buoyed in part by the warm reception that has been given to the $1.2 billion rejuvenation of the rest of the campus, which was designed by Diller, Scofidio & Renfro and completed this fall.

The Philharmonic also now feels a sense of urgency. Many orchestras have folded in the past 10 years while patrons have moved away from season-long subscriptions in favor of single ticket sales.

“If you’re not thinking about the way in which our art form and music and audiences are evolving, you’re not serving the art form long term,” said Matthew VanBesien, who this year became the orchestra’s executive director. “You really want to build this next great hall in a new way, to do the kinds of things you maybe are doing but want to do in a more compelling way or maybe can’t even imagine yet.”

The parties acknowledge they have yet to resolve several important questions, including the budget for a new design, how fund-raising will be divided between the orchestra and Lincoln Center and where the Philharmonic will play during construction.
