When Diller Scofidio + Renfro (DS+R) unveiled its expansion for The Broad last year, it continued the “veil and vault” concept the New York office introduced to the site in 2015. This week, shovels broke ground on the major addition to the Los Angeles art museum that brings the building’s interior surfaces to its facade. This week’s groundbreaking ceremony was attended by Los Angeles Mayor Karen Bass, Elizabeth Diller, The Broad founder and executive director Edythe Broad, and local politicians and business leaders. It comes not long after the passing of Ricardo Scofidio. DS+R first shared its vision for an addition to The Broad last March. The 55,000-square-foot expansion will contain newly acquired works by Lauren Halsey, David Hammons, Martin Puryear, Amy Sherald, and Hank Willis Thomas, among others. It will grow The Broad’s footprint by 70 percent from Grand Avenue to Hope Street. Elizabeth Diller attended the groundbreaking with Los Angeles Mayor Karen Bass.

The expansion is set to open in 2028, ahead of the 2028 Olympic and Paralympic Games. “As Los Angeles prepares to welcome the world for the 2028 Olympic and Paralympic Games, there is no better time to celebrate the launch of The Broad expansion,” Mayor Bass noted at the groundbreaking.
