Germany Shell Building

The shell house is unique because of its shape, construction and materials. Fahrenkamp creates the dynamics of a wave: the building always jumps forward by a window front along its length and at the same time increases by one storey. The rounded corners of the building and the windows reinforce the wave movement. So it's a nice building to ply withe the camera there ;)....
BTW,
The Kulturforum at Potsdamer Platz with further sights of Berlin Modernism is located very close to the Shell House.

You will find many point of views there, so perfect, when you like minimalism or architecture views.
