The firm will deliver the fit-out for building 8 at the Belgravia scheme, which forms part of phase four of the long-running project.
Multiplex is the principal contractor for phase four, which consists of three blocks, arranged around a private courtyard.
The designer for this phase is Eric Parry Architects. Previously Ardmore delivered fit-out on the other two buildings of phase four.
A spokesman for Ant Yapi UK said: “We are delighted to announce that Ant Yapi UK is embarking on its latest project, Building 8 at Chelsea Barracks in Belgravia.”
