designed by Perkins and Will & Hirsch Bedner Associates
Altamount Road, Cumballa Hill
This building is the most controversial on this list. From an architectural point of view, it’s interesting. The building’s main theme is a folded line and in between the curves the residential parts have been placed. Giving the building big terraces. The design is airy, view orientated and at one side has a green wall.
Its controversy lies in the fact that this whole building of 27 floors is home to a single family. And that not alone, it is estimated to be the world’s most expensive private house It’s valued to cost 2 billion dollars. It’s not even clear if the house is inhabited. This is deliberately kept a secret to avoid attacks by Al Queda.
The building is surrounded by slums. The view from here must be shocking.
