Switch House | Herzog & De Meuron

The new extension of the Tate Modern gallery in London, designed by Herzog & De Meuron. 

The Switch House features an exterior of latticed brickwork and folded surfaces.

While it's interiors are a hard and abstract concrete running from the angular top floors down to the vaults in the basement of the building. 

A spiral staircase is the centre piece in the core of the building, almost feeling like an entrance of a cave.
