A tapering tower whose entire load is carried by an expressed diagonal steel grid with no vertical columns, triangular glazing panels following the structural rhythm exactly, node connections detailed as the main visual event, clear sky, low viewpoint emphasising the taper, 24mm lens, ultra photorealistic, 8K
