During the design phase sketches of the building were published in Danish newspapers. Critics feared a destruction of the traditional skyline of Copenhagen. The building was compared to a punch card. Jacobsen's response was: ""it’s funny, for that is actually what it looks like when the windows are open on a hot summer’s day."" Another term used was introduced by Jacobsen's former associate Erik Møller, who called it the 'glass cigarbox'. The promoter of the international style, Philip C. Johnson, said it was the worst copy of Lever House. Jacobsen responded: ""At least, it came in first when they held a competition for the ugliest building in Copenhagen.""
