NeXT Computer Offices(archive.org)

  Jobs found office space in Palo Alto, California, at 3475 Deer Creek Road, 
  occupying a glass-and-concrete building that featured a staircase designed by 
  the architect I. M. Pei. [0]

  NeXT's expansion prompted renting an office at 800 and 900 Chesapeake Drive, 
  in Redwood City, also designed by Pei. The architectural centerpiece was a 
  "floating" staircase with no visible supports. [0]

  One of their main features was the wood-and-steel staircase, which seemed to 
  float in mid-air, and came at a high cost of having elevators removed, upon 
  Steve's demand. The stairs would later inspire similar designs in the Apple 
  Retail Stores. Other striking features included a marble dining area and 
  $10,000 sofas. This lavish corporate environment was later understandably held 
  as evidence of what went wrong with NeXT. [1]

  I had planned to shoot Steve with the incredible floating cement staircase 
  I.M. Pei designed for him in the lobby, a precursor to the clear glass version 
  that later became famous in the Apple stores. We begin setting up lights and 
  talking things over with Steve’s team. Finally Steve came storming in, hours 
  late due to traffic on his way down from Pixar, and in a terrible mood. He 
  took one look at my set up and announced, “This is just stupid. We are not 
  doing this.” [2]
