The London-based practice, which saw off some big name architects to land the job back in April (AJ 28.04.05), has dreamt up a stadium capable of holding 50,000 spectators.
The £200 million project will have four tiers of seating on three sides of the stadium and has been designed to give every single spectator an unobstructed view.
According to an HOK Sport spokesperson, the ground will boast a 'transparent shimmering form' and will become an 'ephemeral addition to the skyline of Dublin'.
Describing the scheme, HOK Sport chief Rod Sheard said: 'The stadium has been designed to be distinctive and to complement its setting in the heart of the city, creating a national arena that will be globally recognised as the home of Irish rugby and football.'
Full planning permission for the scheme, which has been developed with local architect Scott Tallon Walker and engineer Buro Happold, is due to be submitted in December.
