Signing the new executive order on Thursday, the president said: "We like the Oval Office, and it's a symbol, like the White House itself. It's a symbol of our country and the greatness of our country."
He added that world leaders who have visited in recent months have complimented his decorative changes to the room.
Trump said the White House and the Oval Office had been in need of repairs before his changes, calling it "badly damaged". He described broken windows, cracked walls and broken stone.
Many of the noticeable changes, though, were cosmetic, including a large gold plaque reading "Oval Office" outside the space, paving over the Rose Garden and adding a new helicopter pad.
