The highest building in the world is the Burj Khalifa in Dubai. Located in the United Arab Emirates, it stands over 2,700 feet above the ground.
The question could be about the highest mountain? Which is Mount Everest. The current highest building is Burj Khalifa.
In 2002, the world's highest building was Petronas Towers due to its spires on the top. But if you consider an antenna as a part of the building then it was Willis Tower (formerly Sears Tower). But the antenna is not a part of the building, that's why Petronas Towers was the highest building back then. FYI, Willis Tower has 110 living floors and Petronas Towers has 88 living floors.
