The Infinitus Plaza serves as the new headquarters for purveyor of traditional Chinese herbal health products Infinitus. Though you might not be able to tell at first glance, its design has a lot in common with ZHA's Leeza Soho. Just as that project was bisected by a subway tunnel – it's actually made up of two towers, linked by bridges and enclosed in glass – this new building straddles an underground metro tunnel too. Building directly on top of the tunnel would have been problematic, so the firm repeated the same basic idea and linked two buildings with multiple bridges again.
