A $100M Expansion Taking Shape at 221 S. Grand Avenue

Steel is now rising at The Broad’s $100 million expansion in Downtown Los Angeles, marking a major milestone for one of the city’s most visited cultural institutions. The project will add approximately 50,000 square feet to the museum, increasing its overall footprint by roughly 70 percent. Completion is expected in 2028.

What the 50,000 Square Foot Addition Means for DTLA’s Cultural Core

Designed by Diller Scofidio + Renfro, the same firm behind the original museum, the addition will rise along Hope Street. The expansion requires partial removal of the building’s iconic honeycomb façade made of 2,500 fiberglass-reinforced concrete panels. In contrast to the original exterior, the new volume will feature a more concrete forward design language. New elements include two open-air courtyards, space for live programming, and an art storage gallery allowing visitors to view works previously kept behind the scenes. For Downtown Los Angeles, the expansion reinforces Bunker Hill’s role as the city’s cultural epicenter.

What This Means for Grand Avenue’s Long-Term Investment Story

The Broad joins other large-scale institutional projects reshaping Bunker Hill, including the Colburn School’s $335 million expansion. Institutional investment in cultural infrastructure often precedes and supports private development by driving consistent foot traffic and enhancing neighborhood identity. With more than 2,000 works in its collection and free general admission, The Broad remains a high-volume destination. Expanding capacity strengthens its role as a stabilizing anchor along Grand Avenue. For landlords and developers in DTLA, sustained cultural investment signals long-term confidence in the district’s recovery and mixed-use future.
