The idea behind Paternoster Vents
The aesthetic design is derived from experiments with folded paper, scaled up to 11m in height; the vents retain the proportions of the A4-size paper used in these experiments. The Vents are fabricated from 63 identical, 8mm thick, stainless steel isosceles triangles welded together and finished by glass bead blasting.
