An internal memorandum circulating within federal preservation and facilities offices states that the White House was “excellently preserved” during preparatory demolition work in the East Wing linked to plans for a new ballroom backed by President Donald Trump.

The memo, written after a structural review of the site, concludes that no damage was sustained to the historic core of the executive residence during the initial phase of the project.

The East Wing demolition has been part of a broader renovation initiative intended to create expanded event space on the White House grounds.

The proposed ballroom, championed by President Trump as a way to host state functions and large gatherings without relying on temporary tents, has drawn significant attention in Washington.

According to officials familiar with the review, the demolition was confined to non-historic interior elements and temporary office areas, with strict safeguards in place to protect load-bearing structures and architectural features.

Engineers and preservation specialists reportedly conducted continuous monitoring throughout the process, including vibration assessments and structural integrity inspections.

The memo emphasises that protective barriers, phased removal procedures and oversight by federal architects ensured that the Executive Residence itself remained unaffected.

The ballroom proposal has been framed by the administration as an enhancement to the White House’s capacity to host diplomatic and ceremonial events in a manner befitting the presidency.

Supporters argue that the addition would modernise infrastructure while maintaining respect for the building’s historic character.

Any permanent construction on the grounds of the White House requires coordination with preservation authorities and adherence to federal guidelines governing historic properties.

The review memo appears aimed at addressing questions raised about potential impacts of construction activity on one of the nation’s most iconic landmarks.

Officials say further updates will be provided as planning and design processes advance.
