To emphasize, I don't have a problem with Prussian-era architectural style per se, even if I am aware of the politico-cultural trench warfare behind the reconstruction. But this one building... just strikes me as ugly. Bad ratios, little detail, and it's one big block.

anachronism.

Well, it wasn't a serious proposal :-) But, if the architect is gifted enough, an anachronism can fit in -- see the Reichstag dome.

BTW, I remember, but couldn't find an on-line trace of, a study a few years ago saying that the palace would block air movements and car-polluted air would get stuck -- do you recall anything?
