David Hotson Architect

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 ascends through the full height of the penthouse, linking the entry hall with the structural glass floor of the attic level four stories above. The original riveted steel structure threads through the faceted stairwell and past a structural glass bridge which spans the stairwell at the third level.
