On March 14, 2026, the Trump administration filed plans with the National Capital Planning Commission to build a 33,000-square-foot visitor screening facility for the White House, sited at Sherman Park adjacent to the grounds. The proposal, which calls for much of the structure to be placed below grade, is pitched as a permanent replacement for the trailers and tents the Secret Service uses for large events. Officials say the project will include landscaping and other measures to limit visual impact. The filing comes alongside other recent and proposed alterations to the White House campus, including a separate 90,000-square-foot ballroom proposal.
Key Takeaways
- The administration is proposing a 33,000-square-foot screening center for White House visitors; the entrance would face Sherman Park next to the White House.
- Documents submitted to the National Capital Planning Commission describe the facility as partially underground to reduce visibility and to avoid an existing sewer tunnel in the park.
- The filing states the new center would replace temporary trailers and tents now used by the Secret Service for event screening.
- Landscape restoration, including new tree plantings, is promised in all impacted zones to “reinstate and enhance the park’s character.”
- The screening-center proposal arrives as the administration pursues other major campus changes, notably a proposed 90,000-square-foot ballroom replacing the East Wing.
- The National Capital Planning Commission is scheduled to consider the ballroom next month and will review the screening center plan at the same meeting.
- Public-access and preservation advocates may weigh the trade-offs between long-term security infrastructure and park restoration on federal land.
Background
The Secret Service has long relied on temporary infrastructure—trailers, tents and mobile checkpoints—to screen visitors during high-attendance White House events. Those interim measures are viewed by the administration as operationally adequate but visually and functionally imperfect, prompting a push for a fixed facility that consolidates screening operations. Sherman Park, a public green space immediately adjacent to the White House complex, has been identified in the filing as the planned entrance location for the new center.
President Trump has overseen several notable alterations to the White House grounds and interiors since taking office, including changes to the Rose Garden, decorative updates in the Oval Office and the Palm Room, and the removal of the East Wing to make way for a proposed ballroom. Those changes have repeatedly drawn public attention because they involve historic spaces and established public access. Federal oversight for major changes to the park and grounds falls to agencies including the National Capital Planning Commission, which evaluates land-use and design for the National Capital Region.
Main Event
On March 14, 2026, administration officials filed a design and siting plan for a 33,000-square-foot visitor screening facility with the National Capital Planning Commission. The submission describes a structure sited largely below grade in the park’s west quadrant, a placement intended to limit sightlines from surrounding public areas while avoiding an existing sewer tunnel in the park’s southeast corner. The filing also outlines commitments to landscape restoration, including new tree plantings, to “reinstate and enhance the park’s character.”
The documents state the permanent center would replace the trailers and tents currently employed by the Secret Service for large events, consolidating screening operations into a single, purpose-built space. The administration framed the plan as both a security upgrade and an improvement over the intermittent, temporary infrastructure that has occupied portions of parkland during events. Officials assert that siting much of the structure below grade will reduce its visual footprint and that the project will include restorative landscaping in all impacted zones.
The proposal is being reviewed at the same NCPC meeting where a separate, larger project—a 90,000-square-foot ballroom to replace the East Wing—will be considered. The timing has made the two projects interlinked in public discussion: the ballroom represents an even more extensive alteration of White House property, while the screening center is presented as a functional improvement to event logistics and security. The NCPC meeting, expected next month, will be the first opportunity for federal planners to vote on the ballroom and to formally consider the screening center plans.
Analysis & Implications
Security infrastructure on federal property near the White House necessarily balances operational needs and public stewardship of parkland. A permanent screening center could streamline visitor processing, improve shelter and staffing conditions for the Secret Service, and reduce setup time for large events. But transferring temporary screening operations into a fixed facility raises questions about long-term public access and the precedent it sets for converting park space to security use—an issue that often draws scrutiny from preservationists and open-space advocates.
Placing most of the structure below grade is a common design response to visibility concerns, yet it does not fully eliminate impacts such as access pathways, mechanical systems, ventilation, lighting and entries that alter a park’s layout. The filing’s promise of landscape restoration and new tree plantings addresses some aesthetic concerns, but the effectiveness of such mitigation depends on detailed design, construction staging and post-construction maintenance. Federal reviewers typically require additional design detail and public engagement before granting final approval for such projects.
Politically, the center comes amid a pattern of high-profile alterations to the White House grounds under the current administration. The combination of cosmetic interior changes and larger campus projects means federal planners will weigh not only technical merit and security need but also cumulative effects on historic character and public use. Funding, operational control, and long-term maintenance responsibilities will matter for interagency oversight and for municipal stakeholders in Washington, D.C.
Comparison & Data
| Project | Size | Location | Status |
|---|---|---|---|
| Proposed Screening Center | 33,000 sq ft | Sherman Park (west quadrant), below grade | Filed with NCPC (March 14, 2026) |
| Proposed Ballroom | 90,000 sq ft | Former East Wing site | Under NCPC review (vote expected next month) |
| Temporary Screening Infrastructure | Variable (trailers/tents) | Adjacent to White House grounds | Current operational baseline |
The table above places the new screening center in scale relative to the ballroom proposal and the current temporary facilities. The screening center’s 33,000 square feet represents a substantial, permanent footprint compared with tents and trailers, though it is significantly smaller than the 90,000-square-foot ballroom plan. The relative sizes and siting choices will inform impact assessments covering circulation, landscaping, and subterranean utilities such as the sewer tunnel referenced in the filing.
Reactions & Quotes
Administration filings emphasize mitigation of visual effects and restoration of parkland; federal planners and preservation groups will evaluate those claims during review. Below are excerpts from the administration’s submission and context provided by the filing.
“Most of the proposed structure is intentionally positioned below grade within the park’s west quadrant to reduce visual impact and to avoid a large existing sewer tunnel that sweeps through the southeast corner of the park.”
Administration filing to National Capital Planning Commission (March 14, 2026)
The filing cites below-grade siting as the primary strategy to limit the center’s visual profile and to work around subsurface constraints. Planners will review soil reports, utility maps and engineering detail to confirm that the proposed placement is feasible and that it minimizes unintended damage to park infrastructure.
“Landscape restoration, including new tree plantings, will be provided within all impacted zones to reinstate and enhance the park’s character.”
Administration filing to National Capital Planning Commission (March 14, 2026)
The promise of landscape restoration seeks to address concerns about park character, but it leaves open questions about species selection, long-term maintenance and temporary disruptions during construction. Preservation advocates typically request detailed planting plans and maintenance commitments before supporting such trade-offs.
Unconfirmed
- The total construction cost for the screening center has not been disclosed in the filing and remains unreported.
- The precise construction timeline and when the facility would become operational have not been confirmed by the administration or NCPC.
- Funding sources and whether appropriations have been secured for either the screening center or the ballroom are not specified in the public filing.
- Detailed engineering plans and environmental reviews required to confirm the feasibility of building near the sewer tunnel have not been made public.
Bottom Line
The March 14, 2026 filing signals the administration’s intent to convert temporary security operations into a permanent, 33,000-square-foot screening center at Sherman Park, framed as both an operational upgrade and a park restoration project. The plan’s below-grade siting and promised landscaping are designed to limit visual impact, but the real measure of mitigation will come from detailed engineering, planting plans and NCPC’s review conditions.
As the proposal advances to the National Capital Planning Commission alongside the larger ballroom proposal, key questions remain about cost, funding, construction timelines and long-term impacts on public parkland. Observers should watch NCPC staff reports and any required environmental or historic-preservation reviews for the definitive details that will shape approval and future oversight.
