Following last month’s unveiling of a $500-million plan to upgrade Willis tower, which includes major improvements to its base, it is no surprise that the top of the tower would get some love too. One of the new attractions would allow for guests to descend from the 103rd floor to the 102nd floor by rope in a glass enclosure on the side of the building. Another, called the “Ledgewalk,” would allow guests to walk along a glass ledge cantilevered off the side of the building. The rendering also includes a new glassed-in staircase attached to the corner of the building.

The Burj Khalifa
~ Make a wish and blow it away ~
With a total height of 829.8 m and a roof height (excluding antenna) of 828 m, the Burj Khalifa is the tallest structure in the world since topping out in late 2008.
Designed by Adrian Smith, then of Skidmore Owings Merrill. The design is derived from the Islamic architecture of the region, such as in the Great Mosque of Samarra.. The decision to build Burj Khalifa is reportedly based on the government's decision to diversify from an oil-based economy to one that is service and tourism based.
One Maritime Plaza aka The Alcoa Building, completed in #1967 by @skidmoreowingsmerrill. This is one of the earliest buildings to use seismic bracing in the form of external trusses and X-braces. #sanfrancisco#skidmoreowingsmerrill
