This project is an entry for the 2006 international open design competition for an expansion to Asplund's early modern masterpiece, the Stockholm Public Library. Parallel bar buildings sited perpendicular to the street which Asplund envisioned in his masterplan (most of which was not built to his design) are here inverted from mass to void, reinterpreted as giant hollow structural elements. These act as courtyards which orchestrate natural light and vertical movement at the heart of the new library expansion. Using these structural 'feet' to float the new building mass above the street level offers both an increased flow and public connectivity to the lower level park as well as the ability for the library to finally connect with the upper plateau that was always such a strong feature of the landscape of this extended site. New book stacks are organized as a set of ramping terraces that weave back and forth between small reading nooks embedded within the porous street facade and the large new public reading room situated along the cliff face of the plateau at the 'back' of the site. Each of the conical structural voids adapts to localized programmatic and movement conditions that serve the larger whole.
