The Aplund building is one of Stockholm’s important architectural
landmarks and connecting to such a building requires attention at all
scales. The new building leans forward to touch the Asplund library
making a significant and noticeable yet respectful connection between
old and new.
Hanging Structural System When
looking for intelligent structural solutions we sought to use the
inherent structural logic of the library – the bookshelf. Instead of
creating a building and filling it with book structures (shelves) why
not use the book structures as a building structure? This programmatic
structure combined with the site constraint led to the development of
the overall structure: eight large cores support a three-meter high
space frame. Off of this preliminary structure a dense grid of 1x2
meter steel cables is suspended. This grid extends throughout the
building to support everything from the façade to the book shelves. The
cores shift from their original grids to keep a six meter distance from
the subway tunnel below grade.
Programmatic Distribution & Structural Typology
The library serves three types of occupants - media & books, the
public and the library staff. Each of these occupant groups has a
unique spatial typology and functional needs. The heart of the library
is the mass of book storage areas located from the third to sixth
floors of the new building as well as in the main rotunda of the
Asplund building. The density of the grid allows us to minimize the
diameter of rods creating a delicate lattice of supporting structure
throughout the building. The public reading halls are large-span
inserted spaces within the mass of book stack areas creating dramatic
2-3 floor high cathedrals for reading. Offices are cantilevers off the
west facade. The ground floor and the first and second floors of the
new building house the public spaces.
