The Stockholm Public Library comprises of three parts, the original Eric Gunnar Asplund building on the east of the site, the new library to the west and the link in between forming a new ensemble.
The existing annexes have to be demolished. They do not provide enough space and it would be impossible to maintain proper circulation and orientation.
he new library is as well as the original Asplund building square in plan but smaller and is offset to the west. The new library is a tower block seven stories high and designed as a reinforced concrete structure. This reflects monolithically appearance which refers to Asplunds masonry structure. The link building is a lighter structure where steel and glass has been used for the walls and concrete for central columns and floors.
The elevation of the new library appears to be with randomly placed windows from the outside and a fair-face concrete finish. This stands in contrast to the Asplund building which has been designed in a neo-classicistic order. Internally the large 3 x 3 metres openings create different light situations for the user as well as positions of working desks and reading cells.
The connection between the Eric Gunnar Asplund Building and the new library tower is formed by the link building which also creates the connection between the hill and Odengatan. This link was broken or only difficult to access because of the former annexes.
The new library and the link building are orientated east-west and running parallel to Odengatan. The link building also creates the connection between Odengatan and the hill. The smaller size of the new library in foot print creates more space at the corner Odengatan – Gyldengatan. This space draws a connection to the new sub-way station development further west.
The new main entrance on the tower block provides easy access from the west and the visitor enters the building on the ground floor level which is maintained throughout the building.
