Freitag is a Swiss company run by namesake brothers, using recycled truck tarpaulins and other automotive materials to make bags. The bags are subsequently durable, individual and ‘green’, although veer dangerously close to high school tech class. Reflecting their re-use mantra, their flagship store in Zurich West is made from used shipping containers. Designed by Annette Spillmann and Harald Echsle, the boxes were Gutted, reinforced, piled-up 26 meters high and braced, ranking as Zurich’s tallest structure.
"Optimum use had to be made of the small plot of land right next to Gerold-strasse. The standard 20-foot shipping container was chosen as the basic building block for the construction of an asymmetric tower of 9 containers rising from a 4 x 2 base. Set back from the road, the structural shell of the building emphasizes the size of the adjacent brownfield site. The base is used as a sales outlet, while the tower has become a striking landmark. The circle, from product to building to product, is complete."
Container architecture has a fairly polar spectrum of really bad to pretty good, and I’d ike to vote for this in the latter. Also interesting are LOT-EK and NL Architects efforts.
