I went to Berlin for 4 days during Christmas and it was amazing.
The Coldweather matched the mood and atmosphere of Berlin.
The sky was always grey so the buildings were highlighted even
more then usual. Out of all Renzo Piano, Daniel Libeskind,
Foster, Grimshaw, Mies van de Rohe, Zaha Hadid, Santiago
Calatrava, Grunten/Erst Architects, Murphy/Jahn, Peter
Eisenmann, and others my favourite design of space was Frank
Gehry's DG Bank building on Pariser Platz. It was full of energy
and Movement. It was an awesome trip.
