Richard Serra is working on a new sculpture for David Zwirner.

The major work will be featured at Zwirner’s five-story West 20th Street space, which opened in February of last year, to commemorate the gallery’s 20th anniversary. Though Serra has long been represented by Zwirner’s chief competitor Gagosian Gallery, this will be the sculptor’s third recent solo show with Zwirner. In addition to Serra’s forthcoming large-scale sculpture, set to be unveiled in May 2015, he will have a show of drawings with Zwirner next month—”Richard Serra: Vertical and Horizontal Reversals,” running November 7–December 20—and last spring his early sculptures were highlighted in a mini-retrospective of sorts.

“We’re really working with Richard and his team. They make the calls. We don’t need to worry about what it means—we need to worry about putting on great shows and making this interesting for Richard,” Bellatrix Hubert, a senior partner at Zwirner, told the Art Newspaper.

According to the Art Newspaper, Serra’s installations, which often consists of large sheets of weatherproofed steel, have been considered too heavy for most Chelsea spaces not owned by Gagosian. Indeed, the upcoming Zwirner show was only put together after a team of engineers gave its approval.

It’s possible that Serra will produce more large-scale work for Zwirner in the future, but for now the artist maintains non-exclusive representation with Gagosian, in whose London locations he currently has two solo shows on view (one through November 22, the other through February 28, 2015).
