Peter Eisenman's Berlin/Holocaust memorial Light and Shadow. I like the way the structure of the building creates strong impressions of light and dark. Also the juxtaposition between the natural and man-made forces interests me.
KAIROS / João Quintela + Tim Simon Attention to detail I guess the idea was that the stair can be a part of building skin. For that, the architect made new type of stair. Actually the stair does not exist itself.
