Dublin-based Newenham Mulligan and London-based Grimshaw have been selected by the Royal Dublin Society and Leinster Rugby to redevelop the rugby team’s home arena in Ballsbridge, Ireland. The €20 million redevelopment, announced just before Ireland’s bid to host the 2023 Rugby World Cup, plans to replace the RDS Arena’s old Anglesea stand with one that increases the venue’s capacity to 25,000.
