  • Parking areas and a shopping mall extend beneath the podium as well as a connecting tunnel to the city's existing network of downtown, subsurface shopping arcades.
  • The increased depth of columns at eight points, while acting as supplementary wind-bracing, gives the impression of a softy undulating exterior wall.
  • Clad with 27 tons of Italian travertine marble, quarried at Montecanti near Rome.
  • The walls at the base splay outward slightly (at the lobby and mezzanine levels).
  • The structure is a double-tube system, in which the perimeter walls and a shear wall core combine to bear the load and form stiff resistance to winds.
  • Windows are glazed with bronze colored glass.
  • Located on the 49th floor is The Downtown Club, which has been a Houston tradition since 1972 and is an exclusive private club.
  • This is the world headquarters of the Shell Oil Company.

  • In Spring of 2004, some of the communications equipment on the large antenna was removed for maintenance work, which was finished by August of the same year.
  • The antenna atop the building was once the primary transmitter for KRIV-TV, which began broadcasting the year this building was completed.
  • The building rests on a raised podium and faces City Hall Park.
