The Trump administration has formally disclosed comprehensive blueprints for a significant underground security complex designed to transform visitor access procedures at the White House. The detailed plans, released on Friday, outline the creation of a substantial subterranean screening center located beneath Sherman Park, situated southeast of the presidential residence and south of the Treasury building.
Major Infrastructure Project
This ambitious initiative represents the latest phase in the administration's extensive overhaul of White House grounds and operations. The proposed facility spans an impressive 33,000 square feet and will serve as a permanent replacement for the temporary trailer structures that have historically handled visitor screening before East Wing entry.
Construction Timeline and Purpose
Construction activities could commence as early as August, with the White House administration determined to have the facility fully operational by July 2028. This completion date would fall approximately six months before President Trump's scheduled departure from office. According to official documentation, "The permanent facility will strengthen campus security and enhance the overall visitor experience."
The need for this new infrastructure became particularly pressing following October's controversial demolition of the East Wing, which was cleared to make way for a $250 million private ballroom project. Currently, visitors must queue along Lafayette Park, just steps from Pennsylvania Avenue, awaiting entry procedures.
Visitor Flow and Security Procedures
Under the newly proposed system, visitors will initially enter the facility via an exterior ramp that leads to a sunken plaza measuring 5,000 square feet. This recessed entry area will function as a gathering space where tickets and identification documents undergo verification. The design intentionally allows queues to form along the ramp rather than congesting the adjacent 15th Street sidewalk.
Once inside the facility, visitors will proceed through two distinct security stages: pre-screening followed by primary screening. The seven-lane primary screening area has been specifically engineered to reduce wait times while accommodating current security protocols and allowing for future technological upgrades.
Post-Security Experience
After successfully passing through security checkpoints, guests will travel through a tunnel featuring educational displays from both the White House tour office and the Executive Office of the President. Visitors will then take an elevator upward, emerging inside the secure perimeter of the White House complex where their official visit begins. A single escalator will eventually return visitors to ground level north of the secure fence along East Executive Avenue.
Environmental and Historical Considerations
The planning documents emphasize careful consideration of environmental and historical preservation aspects. The underground placement of the screening center aims to "reduce visual impact" and avoid conflicts with existing infrastructure in Sherman Park's southeast corner. Notably, the monument honoring Union General William Tecumseh Sherman will remain undisturbed at the park's center.
"Landscape restoration, including new tree plantings, will be provided within all impacted zones to reinstate and enhance the park's character," the agenda states. While approximately six trees would require removal, these would be replaced with suitable native species. The site selection was "carefully considered to ensure new elements blend with the park's historic fabric and the city's architectural character."
Collaborative Oversight and Related Projects
Multiple federal agencies are collaborating on this substantial undertaking, including the Executive Office of the President, the United States Secret Service, and the National Park Service, which manages White House grounds. The National Capital Planning Commission, responsible for federal construction oversight, is scheduled to review the proposal on April 2.
The same agenda includes discussion and a final vote regarding President Trump's separate proposal to construct a 90,000-square-foot building featuring his expansive private ballroom where the East Wing previously stood. This ballroom project remains embroiled in controversy and legal challenges.
Personnel Appointments and Legal Challenges
Last month, President Trump appointed his 26-year-old executive assistant, Chamberlain Harris, to the Commission of Fine Arts, one of two bodies required to approve the ballroom project. Harris serves as deputy director of Oval Office operations and holds a political science degree from the University of Albany, SUNY, with minors in communications and economics.
Her appointment followed Trump's dismissal of all remaining commission members in October and his hurried appointment of seven new members in January. The National Trust for Historic Preservation has filed a lawsuit against the president, arguing that he should have obtained approval from both the Commission of Fine Arts and the National Capital Planning Commission before demolishing the East Wing.
A ruling is anticipated shortly, with reports indicating that the federal judge has focused particularly on the use of private donations to fund the estimated $400 million ballroom project, potentially bypassing Congressional authorization requirements. In January, the architect leading the ballroom design also revealed new expansion plans for the West Wing.
