Final answer:
President Theodore Roosevelt renovated the White House in 1902, adding a west wing office for quieter work due to his large family. This reflected his modern vision for the presidency.
Step-by-step explanation:
In 1902, President Theodore Roosevelt decided to renovate the White House to accommodate his large family of six children, and he also built an office onto the west wing to have a quieter workplace. This renovation was part of Roosevelt's overall vision of modernizing the presidency and the White House's operations, including introducing an executive office as a dedicated workspace.
As Roosevelt was a proponent of the 'strenuous life' and actively pursued multiple reforms and modernizations during his tenure, redesigning the White House to suit his family and work better needs fits into the extensive palette of initiatives he undertook.
