Stockholm City Library Extension endeavours to create a place for all the people of Stockholm and its surroundings within a reworked and extended main branch of the Stockholm Public Library. The existing Gunnar Asplund designed building is restored to its original design and its annexes are replaced with a new building reflective of the present aspirations of the institution. The shifted volumes of the new building take their orientation from Karlbergsvagen and Odengatan streets, the Asplund building and the Stockholm Observatory to create an oddly contextual formal ensemble. A new single story entrance connector extends directly into the new building to the east and the Asplund rotunda to the west through a movable walkway. A continuous field at the base of the new building accommodates the café, the news zone, the restaurant and vertical circulation. This continuous field connects directly to the Galleria and the Odenplan transportation hub further to the east. Four voids for light and circulation cut through the volumes of the new building as a negative representation of the four buildings proposed in the original Asplund masterplan for the site. The voids, from east to west are programmed as an entry void, a maze of stairs, a spiral ramp and elevators for people and books. The Asplund building and the new building are programmed as a single entity with areas for young people and children integrated with similar adult areas throughout. The top floor of the new building is shifted back to connect to the Observatory Hill through a planted roof terrace accessed by the ramp spiral. More than simply a library, it is a living room and a community center for all the people of Stockholm.
