Cabinet Room in 1984 Before the construction of the West Wing, offices for the president and his staff were on the eastern end of the second floor of the
Executive Residence. However, when
Theodore Roosevelt became president, he found that the existing offices in the mansion were insufficient to accommodate his family of six children as well as his staff. A year later, in 1902, First Lady
Edith Roosevelt hired
McKim, Mead & White to separate the living quarters from the offices, to enlarge and modernize the public rooms, to re-do the landscaping, and to redecorate the interior. Congress approved over half a million dollars for the renovation. The West Wing was originally intended as a temporary office structure; In 1909,
William Howard Taft expanded the building southward, covering the tennis court. He placed the first
Oval Office at the center of the addition's south facade, reminiscent of the oval rooms in the
Executive Residence. Fortunately, many important documents had recently been moved to the
Library of Congress due to the remodeling of the West Wing. During 1930, Hoover had the West Wing rebuilt and added air-conditioning. and built an unobtrusive "penthouse" storey. The directive to wring the most office space out of the existing building resulted in narrow corridors and generally small staff offices. Gugler's most notable change was the addition to the east side containing a new Cabinet Room, Secretary's Office, and Oval Office. The location of the new Oval Office gave presidents greater privacy, allowing them to slip back and forth between the Executive Residence and the West Wing outdoors on the covered portico, without being in the view of the staff or press indoors. As the size of the president's staff grew over the latter half of the 20th century, the West Wing could no longer house the entire staff. Today, most of the staff members of the
Executive Office of the President are located in the adjacent
