Seoul's Lotte World Tower (rank 6, 10.1% Vanity Ratio) is South Korea's tallest building and the world's sixth-tallest by honest height at 499 metres occupied. Completed in 2017, the tower integrates a shopping mall, office space, hotel, and residential floors within a single structure. The 499m occupied height represents the highest floor you can stand on in the building - the tower's architectural top is 555m, with 56m of spire above the occupied zone. Seoul Observation Deck on floor 123 at 499m is one of Asia's highest publicly accessible viewpoints.
Buildings ranked by Honest Height - the elevation of the highest occupied floor. Not architectural top. Not spires. Not decorative steel nobody rides an elevator to. The gap between the two is the Vanity Ratio. See the full methodology.

Lotte World Tower is 499 metres occupied and 555 metres to the tip. A 10.1% Vanity Ratio is not a low score but it is not exceptional. The building is genuinely enormous. The observation deck is at 499 metres and it is outdoors. Seoul built something genuinely tall and then added a modest crown on top. This is the architectural baseline that many newer buildings fail to meet.
