There's nothing new under the sun: every once in a while, an old building needs to be demolished to make space for a new one. In this case, an old 1960s tower in London needs to be cleared to make way for Richard Rogers' new tower.
So why did I post this, you might wonder? Well, look closely at the way this building is being destructed: it's being done from the bottom up. This has to do with the method of construction: the floors hang from a beam at the top level, which is supported by the concrete core.
