"Can you really build in any height, width and depth with GRID? And take it apart again, GRID by GRID?"
Yes, you can.
This 15 meter high art installation designed by Cobe Architects for Udviklingsselskabet By & Havn (Copenhagen) is a good example of the repeated GRID structure's strong visual effect.
7 Super Cubes, made of 3,136 GRID cubes, became a landmark for the opening of Nordhavn, Copenhagen, in 2014. Placed next to and above each other the ‘basic cubes’ were transformed into a complex and sculptural installation.
