In 1948, Truman ordered an addition to the exterior of the White House: a second-floor balcony in the south portico, which came to be known as the Truman Balcony.
The addition was unpopular.
Some said it spoiled the appearance of the south facade, but it gave the First Family more living space.
 The Truman family moved into nearby Blair House during the renovations.
As the newer West Wing, including the Oval Office, remained open, Truman walked to and from his work across the street each morning and afternoon.

On November 1, 1950, Puerto Rican nationalists Griselio Torresola and Oscar Collazo attempted to assassinate Truman at Blair House.
On the street outside the residence, Torresola mortally wounded a White House policeman, Leslie Coffelt.
Before he died, the officer shot and killed Torresola.
Collazo was wounded and stopped before he entered the house.
He was found guilty of murder and sentenced to death in 1952.
Truman commuted his sentence to life in prison.
To try to settle the question of Puerto Rican independence, Truman allowed a plebiscite in Puerto Rico in 1952 to determine the status of its relationship to the United States.
Nearly 82 percent of the people voted in favor of a new constitution for the Estado Libre Asociado, a continued 'associated free state.'
