Truman wanted the White House to remain the presidents' home. It has to be fireproof and bombproof for this. Underpinning for the house's exterior walls stretched twenty-four feet into a new foundation, and a steel framework was built to support the repaired internal walls. The roof is made of asbestos shingles covered by a tin plate, but it is the water system that makes this building special. The plumbing inside the house is separated from the heating and air-conditioning systems, so if something breaks down in one area, it doesn't affect the other parts of the house.
The White House was originally built with a central heating and cooling system, but these were replaced after the Truman administration with a hot-water heater and an air-conditioner. The heating system uses gas pipes and radiators, while the cooling system consists of two large air conditioners that drive a single compressor through a control panel located in the basement garage. Both the heat and air conditioning are connected to a single pole, which can be turned on or off by someone at the top floor. If the president is out of town or in transit when a crisis strikes, then the first assistant secretary for public affairs can activate the emergency plan by pushing a button on the wall next to where they work.
In conclusion, the White House is a fireproof and bombproof office building that serves as the official residence of the president of the United States.
"Even we don't know what it is," he continued. The White House, which was built between 1792 and 1800, has seen a number of changes and additions to its main building and grounds throughout the years. During WWII, a bomb shelter was built beneath the East Wing, which was subsequently transformed into an operations room. President Truman used this room to speak with generals and other high-ranking officers through a system known as "the open microphone."
The White House bomb shelter was revealed by President Obama in a speech on May 20, 2011. In the speech, he said that when he first took office, there had been concerns about security after the 2001 terrorist attacks. Thus, in 2006, the federal government began work on a plan to protect the White House from future threats. The project included construction of a deep bunker located under the East Wing of the White House.
Obama said that when he heard about the shelter, his initial reaction was, "They must not have told me about it." He added that he was surprised to learn that no one living in the White House at the time knew about the facility. However, later that day, Press Secretary Jay Carney announced that a presidential decision had been made to include the shelter in any future plans for the White House.
According to the Associated Press, Obama's decision was based on recommendations made by Frank J. Giampoli, who was hired by the Department of Homeland Security in 2007 to review the nation's protective measures.
On October 13, 1792, the cornerstone of the White House was laid. The President's House, also known as the Executive Mansion, was known as the White House as early as 1812. It was built of white-gray sandstone that contrasted strongly with the red brick used in adjacent structures. The house was two stories high, with an attic room where George Washington kept his books.
The site on which the White House stands had been set aside by William Penn for his own use as a burial ground, but he allowed the American government to build there if they could find a use for it. When the city of Washington was founded in 1790, the area was already established as a public park called "L'Enfant Plaza". This is why there are no streets named after people who contributed to its development - because they were all drawn from L'Enfant's original plan for the city!
After the War of 1812, Congress wanted a new capital city to replace Philadelphia, which it felt was too far away from the other cities of the country. Washington was chosen over Baltimore or another location farther up the Potomac River. When the city was planned, lots were sold to finance construction of new houses for officials and their families. These were arranged around a large open space now called "Capitol Square", and at one end of it stood the White House.
