In contrast to the Apple Stores in New York, the framework conditions for the glass construction in Glasgow were considerably more favourable: no earthquake zone, no lift in the staircase core and a basic building structure that enabled the stairs to be suspended below the ceiling. Below, two clamps bracing the sideways abutting, all-glass guardrails are fixed onto the 12mm stainless-steel rods. The suspended ceiling and the rails merge into one and lend the whole construction an uncanny lightness, which is further emphasized by the discontinuation of the glass cylinder which otherwise stands in the well hole. Old and new are combined with timeless, elegant transparency, without marring the view of the structure and the beauty of the old architecture. Furthermore, chemically hardened glass creates distortion-free optical characteristics.
