For all of John McAslan’s enthusiasm for Sydney’s new metro, he’s particularly proud of the archway at the base of the heritage building that forms part of the new concourse at Central Station.

The London-headquartered McAslan + Partners came into the orbit of the $21.6 billion Sydney Metro because Laing O’Rourke was bidding to build parts of it; the construction firm had worked with McAslan on his acclaimed 2012 redesign of London’s King’s Cross station. McAslan + Partners designed the Sydney’s new Waterloo metro station and collaborated with Woods Bagot who were lead architects on the Central Station.
