What kind of year would this have been without starchitecture? Well, for starters, there'd be no record-breaking $90M penthouses, no plans for Ice Cream City and no residential forests in Singapore. There'd be none of Bjarke Ingels' cool-kid flourishes, none of Zaha Hadid's signature curvature, and certainly none of Frank Gehry's mindbending deconstructivism. But, as luck would have it, 2012 was a bountiful year for pie-in-the-sky design from architecture's biggest names, a year when some of the most ambitious arrested developments were renewed and some incredibly over-the-top renderings were unveiled. Above: 25 of the most fantastic projects completed, proposed, or restarted in 2012 by folks like Norman Foster, Christian de Portzamparc, Jean Nouvel, and more. Do have a look.
