White House Ballroom Construction

WASHINGTON, DC - APRIL 11: Cranes overlook the White House, as construction of the new ballroom extension continues, following demolition of the East Wing, on April 11, 2026 in Washington, DC. Construction on President Trump's $400 million White House ballroom project can proceed because of national security concerns, an appeals court ruled. The National Trust for Historic Preservation, a nonprofit group chartered by Congress to help with preservation efforts for historic buildings in the US, began suing Trump over his plans for a 90,000-square-foot White House ballroom last year.
