The project includes proposals for a 25-storey residential tower which, if given the go-ahead, would become one of the tallest buildings in Ireland.
The Dublin-based practice has also drawn up plans for a state-of-the art conference centre, spa, eight-screen cinema and a new vehicular bridge to ease local traffic congestion.
Phase two of the town's riverside regeneration programme, the Southbank scheme follows in the wake of the neighbouring Scotch Hall development which was completed in December 2003.
'Between them, Scotch Hall and Southbank will deliver quayside pedestrian walkways of around 400 metres, lined with cafes, bars and other facilities, ' said Gerry Barrett of developer Edward Holdings.
'The riverside, so long the industrial heart of Drogheda where generations worked and toiled, will now become a place to linger and enjoy.'
