The National Trust for Historic Preservation, a privately-funded nonprofit organization chartered by Congress in 1949 to facilitate public participation in the preservation of historic sites of national significance, has filed suit in the US District Court for the District of Columbia against various individuals and agencies of the government asserting that ongoing construction of the White House ballroom is unlawful and asking the court to halt further construction activities until the government complies with the law by going through the legally mandated review processes, including a public comment period.
Donald Trump had crews demolish the White House’s East Wing in October 2025 to make room for a White House State Ballroom, which is planned to be nearly twice the size of the White House.
“The White House is arguably the most evocative building in our country and a globally recognized symbol of our powerful American ideals. As the organization charged with protecting places where our history happened, the National Trust was compelled to file this case,” said Carol Quillen, President and CEO of the National Trust for Historic Preservation, in a statement to the press.
“Submitting the project to the National Capital Planning Commission for review protects the iconic historic features of the White House campus as it evolves. Inviting comments from the American people signals respect and helps ensure a lasting legacy that befits a government of the people, by the people, for the people.”
The filing makes several claims: construction has commenced even though plans have not yet been filed with the National Capital Planning Commission as required by the National Capital Planning Act; no adequate public environmental assessment or Environmental Impact Statement has been prepared as required by the National Environmental Policy Act (NEPA); and Congress has not yet authorized construction of the building as it is required to do when construction is proposed in any federal park in the District of Columbia (the White House sits in The White House and President’s Park).
In addition, the filing argues that the President, in disregarding these laws, is violating the Property Clause of the Constitution, which reserves to Congress the right to dispose of and make all rules regarding property belonging to the United States.
In mid-October, the National Trust submitted a letter to the National Capital Planning Commission, the National Park Service, and the Commission of Fine Arts calling for a pause in construction until the legally mandated review processes were completed.
The National Trust raised concerns that the massing and height of the proposed new construction would overwhelm the White House itself and permanently disrupt its carefully balanced classic design, citing the Secretary of the Interior’s Standards for Rehabilitation, which “offer clear guidance for construction projects affecting historic properties,” the organization’s statement said. “Our concerns went unaddressed.”
The National Trust is currently the sole plaintiff in this case and has retained Foley Hoag as outside counsel. “We stand ready to assist the National Park Service, the White House, and relevant review agencies in exploring design alternatives and modifications that would accomplish the objectives of the Administration while preserving the historic integrity and symbolism of the People’s House,” the organization’s press release said.
The Society of Architectural Historians also expressed “great concern” over the project, stating that a major change to such a historic building should be subject to a thorough review process.
The American Institute of Architects (AIA) has expressed concern and offered recommendations in five areas: establishing a qualifications-based architect selection process, enacting a rigorous historic preservation review, prioritizing transparency and public accountability, considering “proportionality” and “design harmony,” and leveraging collaboration and expertise across the architecture profession.
The White House is not only part of President’s Park, it is a National Historic Landmark owned by the American people and stewarded by the National Park Service. In 2007, it was ranked second on the American Institute of Architects list of America’s Favorite Architecture.
The lawsuit names the following defendants: The National Park Service and its Acting Director Jessica Bowron; John Stanwich, Superintendent of The White House and President’s Park;
The Department of the Interior, and Secretary of the Interior Douglas Burgum; The General Services Administration and its Acting Administrator Michael J. Rigas; and Donald Trump, in his official capacity as President.
