The opening date for the Broad, the contemporary art museum that will showcase Eli and Edythe Broad’s comprehensive collection, has been pushed back to 2015. The $140 million museum, which is being designed by the New York City-based studio, Diller Scofidio + Renfro, was initially slated to open at the end of this year but construction delays slowed progress.

The delay has given the museum, which will be located in downtown Los Angeles, time to develop plans for a restaurant and landscaped plaza. Diller Scofidio + Renfro have already finalized plans for the outdoor space while architects for the restaurant, which will be located next to the museum, have not yet been selected.

In 1984, lifelong philanthropists, Eli and Edythe Broad, founded the Broad Art Foundation, a lending library of contemporary artworks that have been loaned over 8,000 times to nearly 500 museums and galleries across the globe. The Broad, which will offer free admission, will serve as the headquarters for the Broad Art Foundation.

Museum officials plan to announce the Broad’s new opening date later this year.
