Martin Jochman, the chief in design team, says “We drew our inspiration from the quarry setting itself, adopting the image of a green hill cascading down the natural rock face as a series of terraced landscaped hanging gardens. In the centre, we have created a transparentglass ‘waterfall’ from a central vertical circulation atrium connectingthe quarry base with the ground level. This replicates the natural waterfalls on the existing quarry face.”
