Library Delft University of Technology - Mecanoo architecten

The construction of the main library of the Delft University of Technology was finished in 1997. The design is performed by Mecanoo an architecture office based in Delft. The building has won the Dutch "National Steel Price" in 1998 in the category buildings of steel and hybrid constructions because of the extraordinary use of steel in different parts of the building. But for many TU Delft students, as me, the building is mainly the place were you spent most of your days during the exam periods. In the summer you have your study breaks in the sun on the grass rooftop of the building and in the winter it is Delfts only natural ski track (Delft has a very flat country side), which students take with the weirdest real technical Delft designed sledges. Being on the grass roof top of the building was always more interesting than being inside.
