Richard Rogers's 1986 City of London insurance HQ — services on the outside, atrium core. The Pompidou principle scaled up.
From Wikipedia
The Lloyd's building is the home of the insurance institution Lloyd's of London. It is located on the former site of East India House in Lime Street, in London's main financial district, the City of London. The building is a leading example of radical Bowellism architecture in which the services for the building, such as ducts and lifts, are located on the exterior to maximise space in the interior.
