Tate Modern wing redesigned

Tate Modern, London’s riverside art museum, has revised plans for the new wing that architects Herzog & de Meuron are building, and says the 2012 opening may be delayed because of tough fundraising conditions.

At a news briefing Friday, Tate director Nicholas Serota and architect Jacques Herzog said the new building, designed in 2006 as a jagged cast-glass pile, will now be a brick polygon growing out of, and resembling, the existing Tate. They denied that budget reasons were behind the change.

“It’s not cheaper,” Herzog said. “It’s really to make everything better: more efficient, more compact, more flexible and more green.”
