President Donald Trump's White House announced big plans this week for a major construction project on the White House complex, which will include a separate new grand ballroom addition and a renovation of the East Wing.

The renovation of the East Wing, which houses First Lady Melania Trump's office, among other things, will necessarily involve the temporary "eviction" and relocation of her and her staff for the duration of the project, according to the Economic Times.

It is unclear how long the project will take, but construction is slated to begin in September and, per the White House, should be completed well in advance of the end of President Trump's term.

New grand ballroom addition

"For 150 years, Presidents, Administrations, and White House Staff have longed for a large event space on the White House complex that can hold substantially more guests than currently allowed," the White House said in a Thursday statement. "President Donald J. Trump has expressed his commitment to solving this problem on behalf of future Administrations and the American people."

"The White House is one of the most beautiful and historic buildings in the world, yet the White House is currently unable to host major functions honoring world leaders and other countries without having to install a large and unsightly tent approximately 100 yards away from the main building entrance," the statement continued. "The White House State Ballroom will be a much-needed and exquisite addition of approximately 90,000 total square feet of ornately designed and carefully crafted space, with a seated capacity of 650 people -- a significant increase from the 200-person seated capacity in the East Room of the White House."

The White House revealed that President Trump has held "several meetings" about the project with White House staff, the National Park Service, the White House Military Office, and the U.S. Secret Service. It further shared that McCrery Architects had been selected as the lead architect, who would be joined by Clark Construction and the AECOM engineering team.

The project will begin in September and is estimated to cost around $200 million -- and will be funded by Trump himself, plus private donors instead of taxpayers -- "and it is expected to be completed long before the end of President Trump’s term."

The statement added that the new grand ballroom addition "will be substantially separated from the main building of the White House, but at the same time, its theme and architectural heritage will be almost identical."

East Wing will be "modernized"

White House press secretary Karoline Leavitt shared the news during Thursday's press briefing, along with some photos and renderings of what the new ballroom addition will look like once it is completed, and said, "As you can see, it will come off of the Executive Mansion as it sits today, and the East Wing will be modernized and renovated."

She also shared a statement from White House Chief of Staff Susie Wiles, who said, "President Trump is a builder at heart and has an extraordinary eye for detail. The President and the Trump White House are fully committed to working with the appropriate organizations to preserving the special history of the White House while building a beautiful ballroom that can be enjoyed by future Administrations and generations of Americans to come."

Asked a few moments later if the East Wing would be "torn down" during the renovation, Leavitt replied, "So, the East Wing is going to be modernized. The necessary construction will take place. And for those who are housed in the East Wing, including the Office of the First Lady, the White House Military Office, the White House Visitors Offices, those offices will be temporarily relocated while the East Wing is being modernized."

"A great legacy project"

ABC News reported that the grand ballroom addition is just the latest, and probably not the last, project President Trump has undertaken to update and put his personal touch on the White House during his second term in office.

Earlier this year, Trump oversaw the installation of two large flagpoles on the North and South Lawns, and a project to install a paving stone patio over the central grass of the Rose Garden is currently underway. He has also redecorated the interior of the Oval Office with additional gold trim, picture frames, and furnishings.

During an executive order signing ceremony later on Thursday, Trump told reporters that he'd hired "the best architects and engineers" to construct the "top of the line" ballroom addition, which is modeled after the grand ballroom at his Mar-a-Lago resort in South Florida.

"I'm good at building things. And we'll get it built quickly and on time. It'll be beautiful," he said. "I always said I was going to do something about the ballroom because they should have one. So we'll be leaving it. It'll be a great legacy project, and I think it'll be special."
