 A 48,200 sq m (519,000 sq ft) mixed used project for the north eastern quadrant (immediately north of Euston Tower) was completed in July 2013.The "Giants Causeway" of Regent's Place - the project called for an innovative and stylish seating arrangement to be designed in a style similar to that of the Giants Causeway in Northern Ireland.This has been achieved by manufacturing differing sized blocks using Spanish Blue granite; they have been hollowed out to varying degrees and set onto galvanised steel frames, creating a variance in height.
