The private elevator landing opens into a tall vestibule, tapering upward to a seamless rectangular oculus which provides a view of the sculpted summit of the adjacent skyscraper.
From the elevator vestibule, the floor slopes gently upward, passing under the twisting shaft of the stairwell to arrive at the main level of the penthouse.
The stairwell shaft ascends through the full height of the penthouse, visually linking the entry hall with the structural glass floor of the attic four stories above.
The stair itself wraps around the stairwell. The facetted surfaces of the stairwell converge on apertures, trimmed in mirror polished stainless steel, which provide views into and through the stairwell from the surrounding spaces.
At the third level a structural glass bridge traverses the stairwell shaft passing through stainless-trimmed openings at either end.
The original riveted steel structure –clad in intumescent paint- threads through the faceted stairwell slipping through apertures into adjacent rooms.
