"Dublin – it's time to look up." That was the message of ads that appeared in newspapers this weekend.

The full page ads – placed by Johnny Ronan's property development company – say that Dublin will miss the opportunity to be an international player in the future if it didn't start to look up to solve the city's space problem. 

To explain the potential benefits of embracing high-rise buildings in the capital, Kieran and Shane were joined by Richard Coleman, Townscape and Heritage consultant with the Ronan Group.
