President Trump’s plan to add a grand ballroom to the White House, which involves beginning demolition of part of the East Wing this week, marks a significant moment in the ongoing evolution of the historic building. This ambitious project is not the first time a president has personalized the White House to suit their vision and needs.

Over the years, presidents such as Teddy Roosevelt and Barack Obama have implemented their own modifications to the iconic structure. One of the most notable transformations was undertaken by Harry Truman, who spearheaded a comprehensive modernization effort of the White House, originally constructed in 1792.

According to the White House Historical Association, the South Portico, North Portico, East Wing, West Wing, and the Truman Balcony were all initially met with skepticism but have since become integral features of the presidential residence. “Today, we can’t imagine the White House without these iconic elements,” the association noted this week.

Yet, the scale of Trump’s endeavor is unprecedented, said Ed Lengel, former chief historian for the White House Historical Association. In his conversation with The Hill, Lengel emphasized, “There’s never been anything like that before. I think I can say that with total confidence. There’s been nothing on that scale, even close to that scale, has ever been done before.”

“There’s never been anything like that before. And I think I can say that with total confidence. There’s been nothing on that scale, even close to that scale, has ever been done before,” he said.

Trump envisions a massive ballroom, paid for by private donors, attached to the East Wing for entertaining world dignitaries and other guests. 

The White House has hit back at criticism of the project, calling it “a bold, necessary addition that echoes the storied history of improvements and renovations from commanders-in-chief to keep the executive residence as a beacon of American excellence.”

Here’s a timeline of other major White House renovations:

1902

The creation of the West Wing, which houses the offices of the president and his closest staff, started under former President Theodore Roosevelt and was completed under former President Taft.

Prior to 1902, presidents would work from different spaces in the executive mansion, but there was no designated spot for official business. Roosevelt wanted a central office for the commander in chief and hired workers to build a rectangular space on the west side of the White House for the first presidential office, which was later called the “Roosevelt Room.”

The Roosevelt renovation was planned and carried out by the “famous” New York architectural firm McKim, Mead and White, according to the White House. 

Roosevelt worked in his new office for the first time on Nov. 5, 1902, and held his first Cabinet meeting there the next day, according to the White House Historical Association (WHHA).

Taft expanded what was called a temporary executive office building into the West Wing seven years later, placing an oval-shaped office at its center.

1933

Former President Franklin D. Roosevelt added 25,000 feet of permanent office space to the West Wing when he took office three decades later, according to the White House.

“A ‘penthouse’ story and an enlarged subterranean office area with a light well were built,” the WHHA said. “The Oval Office was relocated to the West Wing’s southeast corner-its present location-to overlook the Wilson Rose Garden.”

Roosevelt also added an indoor pool in the West Terrace for the president to exercise amid his battle with polio, according to the WHHA. The $12,000 to build the pool was raised by The Daily News, which established the Roosevelt Swimming Pool Fund.

That pool has since been covered by the White House briefing room. But an outdoor pool, built under President Ford, still exists on the South Lawn. It was funded through private donations.

1948

Truman oversaw the White House’s most significant construction project, moving to the adjacent Blair House after parts of the normal residence were deemed unsafe.

Truman in March 1949 asked Congress to create the Commission on Renovation of the Executive Mansion to address severe architectural inadequacies in the White House. It comprised six members: two each appointed by the president, House and Senate.

Truman and his family moved out soon after his re-election in 1948, spending much of his second term in the nearby building that now hosts foreign dignitaries during their visits.

The renovations cost approximately $5.7 million, which amounts to more than $50 million in today’s dollars, according to the Truman Library Institute.

The White House was gutted, but the Trumans sought to preserve the building as much as possible, working together with architect Lorenzo Winslow.

Truman was happy with the result, if not the price tag.

“Bess & I looked over the East Room, Green Room, Blue Room, Red Room and State Dining Room. They are lovely. So is the hall and state stairway,” he said of his return to the residence. “With all the trouble and worry it is worth it—but not 5 ½ million dollars.”

“If I could have had charge of the construction it would have been done for half the money and in half the time!”

1973

Former President Nixon added one-lane bowling alley to the White House.

White House staffers and visitors still occasionally using the bowling alley, located under the driveway leading to the North Portico.

The underground space was paid for by private donors, according to the White House museum. However, it wasn’t the White House’s first bowling area.

Under Truman, a bowling lane was added to the space that is now used as the Situation Room in 1947. At the time, staff started a bowling league. Former President Eisenhower moved the alley to the basement beneath the Old Executive Office Building. 

2009

Former President Obama converted the White House tennis court into a full scale basketball court in 2009. It was adapted for both tennis and basketball use, according to the White House. 

College basketball championship teams and Wounded Warriors have played on the court, according to Obama’s White House.

During his first term, President Trump added a new White House tennis pavilion. The project, overseen by first lady Melania Trump, included a refurbishment of the existing tennis court and the adjacent “Grandchildren’s Garden,” according to a press release at the time.
