Blé Bakery on Agias Sofias in Thessaloniki, Greece, most certainly fits the bill. It was designed by the minimalist architects at Claudio Silvestrin Giuliana Salmaso (London & Milan). It has the world’s largest wood oven – gigantic, at 12 meters (almost 40 feet) tall! And the bakery is built from cob made of white clay from Crete and Milos, plus sand and straw. Blé’s four floors house a patisserie, bakery, delicatessen and a wine and mozzarella bar.
