The TU Delft central library, The Netherlands, designed by the Mecanoo architects designed in
1993 -1995 and built in 1996 -1997.
I walked on the green roof around the cone. The green roof was very pleasant to lay down and I could almost see myself happily rolling down the slope… However it started raining and I had rush down inside. The general feeling while walking on the roof made me remember Oslo Opera House, I think the latter building was influenced by the former (also the shape of the entrance). The difference is that TU Delft library possesses feeling of human scale and the Oslo Opera house has much more sense of grandeur.
The entrance of the library is not accessible for handicapped people(that is surely due to building being relatively old, public awareness has changed, plus the laws have changed), and my attempts to photograph the front nicely were hindered by un-photogenic trash bins (what surely were not a part of original design).
Some more remarks about exterior – the random openings on the concrete wall by the entrance really amused me. Whether consciously architects realised it or not, the origins can be found on defensive walls and their shooting holes around the world, especially similar ones can be seen in Japanese castles.

Interior was pure visual and photographic pleasure. Easy to orient oneself, bright colours, calm and inspiring environment for study. Atrium in the cone structure, brings natural light down to the very center of the building.

The building won several awards: in 1998 National Steel Construction Prize by Dutch Steel Building Institute and in 2000 Award for the Millennium by Corus Construction.
