The New York Times (Charles V. Bagli) reports: It’s official. Frank Gehry is out as the architect for the Barclays Center, an exotic, $1 billion glass-walled arena that is the centerpiece of the long-delayed and financially challenged Atlantic Yards development in Brooklyn, according to government officials and real estate executives who have been briefed on the plans. The design by Mr. Gehry, the award-winning architect behind the Walt Disney Concert Hall in Los Angeles and the Guggenheim Museum in Bilbao, Spain, has been replaced with a less-expensive, $800 million arena. The new design comes from Ellerbe Becket, an architectural firm based in Kansas City, Mo., that specializes in convention centers, stadiums and arenas, and designed Conseco Fieldhouse in Indianapolis, where the Indiana Pacers play.
