Reduction in building footprint was a refining of the design to include the desired functions and capacity within a slightly smaller building. The building has some later vertical extensions which may a relocating of H&V plant.
Airbridges serving the right side of aircraft are not a feature. I think what appears to be this in the fly through is actually the 'spare' airbridge (when a stand block is in use for 2 x wide body rather than 3 x narrow body). One airbridge will be parked and retracted away from the aircraft in this mode. In the simulation it is shown close to the right side of one of the wide bodies, which is just an anomaly of the presentation.
