The library has a long history. The specific typology oft the building serves the storage of knowledge. The carrier material was originally clay tablets, however in the following millenniums, the paper established itself as the main material, for space saving reasons. Yet the library has not reached it-s fully matured state. Digital media have established themselves in our society, which has become unthinkable without them. The personal storage of knowledge is mainly stored on smartphones, computer and tablets, which can be carried around on a daily basis. Therefor it is a justified question, whether libraries as a bare -book museum- are up to date with nowadays society. Hence, one can argue, that the classical library should be complemented through spaces for encounter, where knowledge can be communicated and exchanged. This new building should be available to a broad audience as an additional living room, which invites to spend time and foster communication among visitors. The project site is situated in the harbour of Copenhagen, not far from the royal Danish Palaces, and accommodates a sparsely used bus parking. This project looks in to the library in the change of time. A description of the environment of the building site and the urban analysis is provided in the first chapter , followed by a detailed demonstration of the project through a concept description, plans and a photo-realistic reproduction.
