^^ That is SO WEIRD and yet ULTRA COOL at the same time!!! Awesome thread! I hope more ppl post examples! :yes:
Skyscraper height extensions?
What happens when you can't build an extension to your building beside it? You build on top! 
Any examples you can think of?
This is Euro-Asia Centre, Singapore. Originally built in the 1970s as a 16 floor block.
A 14 floor extension tower was built above it in 2004. Two giant columns and the lift core constructed around the old block and giant transfer beams are used to support the new tower. More like a skyscraper built above another rather than a height extension.
Now in 2007, it is to be recladded and extended again.

Actually looks really good...let's hope there are other examples
The Gothia Towers in Göteborg have already been extended i believe (im sceptical on that one), and one of them will be further extended with five floors (and one additonal tower will be added).
Here is how it will end up like

I'm surprised no one has mentioned the Blue Cross Blue Shield Tower's extension in Chicago. It was originally designed so that an additional 24 floors could be added when they were needed.
Here it is now, and when it's completed:

Hong Kong has been going after illegal structural additions on rooftops for a while now as many of these pose safety, fire, and structural threats.
Peninsula Hotel built an addition (skyscraper portion) over a decade ago :

wow...great thread!
May I ask something? What if some building's construction is too old or too weak to stand new floors? Of course, it wouldn't be extended, but what if some calculations are wrong, and the whole construction falls in? For exp. this one in Singapore? :dunno:

In the case of Singapore's Euro Asia Centre, the top tower is not pressing on the old tower.wow...great thread!

Two giant columns and a new lift core are built around the outside of the old tower. When it cleared the tower, huge transfer beams span the 3 main supports and the new tower builds from there on.
I know in the Blue Cross/Blue Shield example in Chicago, the building was originally "over-designed" in the first place because they knew that sometime in the future it was to be expanded and had already designed the addition before the building was even built. They just never expected needing to expand it so soon after it was built.wow...great thread!
