This is why you don’t design a skyscraper to look the World Trade Center—when it was under attack. A Dutch architectural firm has apologized after complaints that its blueprint for twin skyscrapers in Seoul resembled the Twin Towers on 9/11. The building’s blueprint reveals a cloud-like structure that sticks out of the building, which will hold the buildings’ amenities. The firm says that it had no intention of recreating the image of the attacks. It did not, however, say whether the plan was scrapped.
