This shows how the external skin attach's to the framing. The skin attach's to horizontal steel bars and these are attached to the main framing, the I-Beams. There is fly bracing attached to the universal beams to give the wall extra support and strength. Also in this image it shows that the drain pipes are hidden away. As opposed to having them on the exterior, they run on the inside and run directly parallel with the I-Beam so they are not overly noticed.
