  Since the present Oval Office's construction in 1934 during the administration of President Franklin D. Roosevelt the room has remained mostly unchanged architecturally. More than any president, Roosevelt left an impression on the room and its use. Doors and window frames have been modified slightly. A screen door on the east wall was removed after the installation of air conditioning. President Lyndon B. Johnson's row of wire service Teletype machines on the southeast wall required cutting plaster and flooring to accommodate wiring. The Georgian style plaster ornament has been cleaned to remove accumulated paint, and a series of electrified wall sconces have come and gone.
  
  Though some presidents have chosen to do day-to-day work in a smaller study just west of the Oval Office, most use the actual Oval Office for work and meetings. Traffic from the large numbers of staff, visitors, and pets over time takes its toll. There have been four sets of flooring in the Oval Office. The original floor was made of cork installed over softwood; however, President Eisenhower was an avid golfer and damaged the floor with his golf spikes. President Lyndon B. Johnson had the floor replaced in the mid-1960s with wood-grain linoleum. In 1982, President Ronald Reagan had the floor replaced with quarter sawn oak and walnut, in a cross parquet pattern similar in design to a 1933 Eric Gugler sketch, which had never been executed. In August 2005, the floor was replaced again under President George W. Bush, in exactly the same pattern as the Reagan floor.
