Daniel Libeskind’s new book about his experience designing the tower that is to rise on the Ground Zero site in lower Manhattan is at turns catty and sincere, and takes direct aim at architect David Childs, with whom Libeskind was compelled to pair on the project. “He portrays Mr Childs as patronising and overbearing, and intent on eliminating as much of Mr Libeskind’s vision as possible from the eventual design… for the majority of the time during their weekly meetings, Mr Childs would ‘chatter on about where he’d just been or would lecture me on architecture’.”
