One of the losing entries in the U2 tower design competition may actually be built – but on the north side of the Liffey. Treasury Holdings, the property development company owned by Johnny Ronan and Richard Barrett, has resuscitated its Zaha Hadid-designed scheme and is planning to develop it on a site on North Wall Quay next to the O2 concert venue. “Further development of world-class iconic buildings in Dublin’s docklands is essential for the regeneration of the city, especially along the capital’s waterfront. We need exciting buildings that reflect the future of Dublin and the vibrancy of the docklands if we are to compete with other great cities around the world,” a spokeswoman for Treasury said. “We are presently working with the internationally renowned Pritzker-prizewinning architect Zaha Hadid on an iconic tower for the north docklands which would provide an exciting riverside entry into Dublin city.
