Larsen's Copenhagen-based practice, Henning Larsen Architects, is working for Irish developer Mountbrook Group on the mixed-use scheme that covers a 3ha site on and around the city's Pembroke Road.
Mountbrook paid Eu378 million (£256 million) for the site in 2005 - an Irish record at the time - and a spokesman for the developer admitted the high-profile scheme was likely to cause controversy.
He said: 'The height of the scheme is likely to cause objections. It is a very ambitious piece of architecture compared to the surrounding environment, which includes Georgian houses and some poor standard 1960s buildings.'
The spokesman denied that Mountbrook was expecting the scheme to be cut back and added: 'This is an ambitious proposal and we are hoping that Ballsbridge will get an ambitious and audacious reality'.
Mountbrook expects the planning process to take around 15 months.
