From that, it's not so much a bridge more a set of offices built over a roadway.
The choice presumably was to have just the roadway, or entrance, granting
access to whatever was behind left as it was. Or sling a platform across the
roadway and build something on top of the platform. More than one story would
probably have been impossible for technical/cost or planning reasons. As to
where you'd get cheaper floorspace in Knightsbridge - maybe suspended from a
balloon 100ft up but that would be about it.

This ignore that the building is part of a huge high-ish rise
development that covers the whole block. My guess is it was done for
aesthetic reasons to make it fit into the streetscape a bit better -
it's the kind of thing that planning committees routinely request.
