Post here images of skyscrapers that were built on top of existing building, or look like they have been built on top of building.

Naturally all know this one:

The World Trade Center in Rotterdam was built in the 1980's on top of a 1930's building:

I'm guessing the low section is an old building, no? Avenu Irigoyen in Cordoba, Argentina.

I know of a few more, but I forgot their names.

Buildings of this kind that spontaneously come to my mind are these two:

what do you think this?
Originally the tallest building in Augusta, GA, this is now the second tallest after Riverplace Condominiums. Construction was started on the building in 1913, though a fire in 1916 delayed its completion for several years. In 1973, State Senator Eugene Holly commissioned the blue plate glass penthouse addition at the top. It was built by I.M. Pei and cost $500,000. In 1979, the Lamar Building was placed on the National Register of Historic Places. Today, nearly 90 years later, it is still the most beautiful and recognizable building in the Augusta skyline.

Not really a skyscraper, but the Club Quarters hotel across from the WTC site, had a complete renovation and a modern extension after it was damaged in the attacks.

The white building near the center:
