The entrance and exit to the expanded Swarovski Crystal Worlds was designed by general planners s_o_s architekten. The plan takes its inspiration from the concept presented by artist duo CAO PERROT, who planted a white forest as the threshold to the garden and the Grand Plaza in front of it. Thus, the broad overhanging concrete roof of the new foyer is set amidst a proverbial birch forest, veritably supported by the trunks of the white trees; the walls and ceilings are likewise clad in birch wood. Beneath the roof is the open space for arriving and waiting guests.
