The White House is planning a 33,000-square-foot underground security screening facility beneath Sherman Park, a move that permanently alters the visitor experience and landscape around the presidential residence, with construction tied to the controversial demolition of the East Wing for a new ballroom and a fast-tracked deadline of July 2028.
The Trump administration’s plan to build a vast underground screening center for White House visitors is a pivotal piece of a larger, controversial transformation of the White House grounds, moving from temporary security measures to a permanent, integrated fortress-like complex.
The Core Plan: A Permanent, Underground Solution
Documents prepared for the National Capital Planning Commission (NCPC) reveal a 33,000-square-foot (3,066-square-meter) facility to be constructed beneath Sherman Park, located southeast of the White House and directly south of the Treasury building[1]. For decades, Sherman Park was the outdoor queueing area for visitors before they passed through temporary trailer-like structures and entered via the East Wing. That East Wing was demolished last fall to make way for a new 90,000-square-foot ballroom[2], forcing visitor screening to relocate near Lafayette Park.
The new underground center would feature seven security lanes, explicitly designed to ease processing and reduce wait times. The project timeline is aggressive: construction could begin as early as August 2026, with a target operational date of July 2028—precisely six months before the end of President Trump’s current term, as noted in the plans[1]. This deadline frames the project as a legacy-defining physical change.
Historical Context: The Security Evolution of the White House Grounds
The push for an underground facility is the latest step in a post-9/11 security evolution that has seen the White House grounds become increasingly fortified. What was once a relatively open symbol of democracy has been layered with barriers, checkpoints, and setbacks. The temporary trailer system, a stark visual of that security creep, was always intended as an interim solution. This plan formalizes and deepens that transformation, burying the screening process itself underground and removing surface-level queues from two historic parks.
Simultaneously, the demolition of the East Wing for a grand ballroom represents a competing symbolic priority: reclaiming and repurposing historical White House space for events and spectacle, even as security infrastructure expands beneath it. The National Park Service, which manages the grounds, is a key collaborator on this project, highlighting the interagency complexity of altering federal land[1].
Connecting the Dots: Two Projects, One Overhaul
The screening facility and the new ballroom are not isolated projects; they are twin pillars of a coordinated redesign. Both are slated for discussion and potential approval at the NCPC’s April 2 meeting[1]. This linkage is critical: the removal of the East Wing (the primary public entrance) necessitates a new, permanent screening solution, and the underground location beneath Sherman Park provides that without further fragmenting the surface-level ceremonial spaces like Lafayette Square.
- Project A: 33,000 sq ft underground screening center in Sherman Park. Seven lanes. Target: July 2028.
- Project B: 90,000 sq ft ballroom on the site of the former East Wing.
- Shared Timeline: Both to be approved by the NCPC in April 2026.
- Key Preservation: The statue of Union Gen. William Tecumseh Sherman in the park will remain in place[1].
Public Interest and Unanswered Questions
The plan raises immediate questions about cost, architectural impact, and long-term access. The government document cited is a project synopsis, but detailed budget figures and architectural renderings beyond the basic scope have not been publicly released[3]. Ethically, transforming a public park into a subterranean security zone sparks debate about the balance between symbolic openness and practical security.
For Washington, D.C., this is another chapter in the federal footprint altering the city’s historic fabric. For tourists, it means a completely different, less visible arrival experience. For Secret Service operations, it centralizes and modernizes screening. The accelerated timeline until mid-2028 signals a desire to lock in this physical legacy before a possible electoral shift.
Why This Matters Now
This isn’t just about a new building. It’s the physical manifestation of a security-first philosophy being etched into the White House’s very geology. By burying screening, the administration attempts to solve two problems at once: enhancing security throughput and preserving the above-ground park aesthetics. However, it creates a massive, permanent underground structure in a historic park—a significant intervention with unknown long-term maintenance and preservation implications.
The parallel ballroom project adds another layer: the grounds are being redesigned for both maximum security and maximum spectacle. The public’s traditional vantage points and access routes are being quietly reconfigured. The approval by the NCPC in April will be the first formal test of this dual vision’s viability.
The ultimate analysis is clear: the White House is permanently fortifying its perimeter in a way that was once unthinkable, all while pursuing a grandiose entertainment venue. The underground screening center is the less glamorous, but arguably more consequential, half of that equation.
