Interesting theory. My own theory is that, good as it was, Parry's office for blue chip companies was never going to win during the worst recession in 60 yrs. Protos was really not that fantastic. The way the building worked and the architecture had almost nothing to do with each other. Frettons Fulsang had some nice ideas but suffered from being poorly detailed in places (as opposed to the immaculate detailing of Parry's office). Liverpool One would also have been a politically contentious choice during a recession. This leaves the 2 health care facilities by AHMM and RSHP. RSHP won because it is more avowedly 'architectural' than AHMM's building which thought impressive, seemed overly research and science driven rather than 'authored'. Next year? Fretton, Caruso St John, Chippo? They're all mates aren't they? Chipperifled could have two buildings on the list (Barcelona).
Fuglsang doesn't seem that amazing (D&B procurement, painted brickwork? Then again you've seen it in the flesh). I think Parry's was better This building is all about the elevated glass envelope, which is beautifully detailed. Where the building is clad extensively in that formed solid panel (photos of which are mysteriously absent from your collection), it is much less successful. The interiors are also much more prosaic than you expect looking at the luxurious bomb proof glazed facades (just standard office space)
