Holles St maternity hospital The firm has also been involved in numerous nationally important building projects, ranging from the former University College Dublin on Earlsfort Terrace which is now the National Concert Hall to the redevelopment of Smithfield Square. G&T Crampton was also behind the National Maternity Hospital at Holles Street, the American Embassy in Ballsbridge and commercial schemes like Wynn’s Hotel in Dublin city centre – which was rebuilt after being set on fire by incendiary bullets during the 1916 rising. A photographic archive of hundreds of projects on which G&T Crampton worked was donated to University College Dublin in 2017.
