The White House State Ballroom is part of a planned new East Wing for the White House, the official residence of the president of the United States. The new East Wing will replace the original, which was torn down in October 2025 in preparation for the new wing's construction. The site, in Washington, D.C., has been under construction since September 2025. Announced in July 2025, the purpose of the 89,000-square-foot (8,270 m2) expansion is to add a venue with a higher seating capacity than the East Room for formal events such as state dinners. The project has been criticized for its funding, design, permitting process and destruction of historic architectural and landscape features. The National Capital Planning Commission approved the final project design in an 8–1 vote on April 2, 2026. The project's above-ground construction has faced legal challenges, with construction as of April 18 being allowed to continue until June 2026.
