Questione giuridica chiave
Whether the grant of the areal development bonus satisfied the special quality requirements for such developments.
Decisione estratta
No. The Federal Supreme Court held that the lower court's approval was arbitrary because the project, as such, did not deserve the characterization of especially good design required by law.
Motivazione estratta
The cantonal court relied on a comparison with an imaginary alternative of separate buildings, which is conceptually and legally unsound. Section 71 PBG requires the planned development itself to merit the label of especially good design in relation to the setting, not merely to outperform a hypothetical inferior alternative.
