ESB should go back to drawing board with office plan
If the ESB is looking for competently designed buildings to replace their building stock in Fitzwilliam Street in Dublin, there are well-established processes in place, eg, advertising seeking competent firms to undertake such work, selecting a firm following interviews, short-listing, etc.
Under any of these processes, the ESB would get from the architectural profession a reasonable and efficient building, and there are buildings all over Ireland that are testimony to this.
