U2 members Bono and the Edge have embarked on a €150 million project to transform Dublins historic Clarence Hotel into a nine storey 140-bedroom five star hotel, complete with a giant glass atrium and glazed rooftop sky bar with views over the city.
The plans will quadruple the size of the building and the main feature will be the oval glass roof, nicknamed sky catcher.
Irelands planning body An Bord Pleanala granted permission for the development with the proviso that the public will be granted access.
The owners seemed happy at the news and will be looking forward to seeing the final result.
"We are delighted that An Bord Pleanala has given us the green light for Norman Fosters design for The Clarence," a statement read.
"Its great news for the team that has worked so hard on this project."
The building was designed by architect Norman Foster, who was also responsible for the worlds largest single span glasshouse, The Great Glasshouse in Carmarthenshire.
