After years in the pipeline, designs have finally been released for the National Library of Israel, Jerusalem, by architecture firm Herzog & de Meuron.

The Swiss company was appointed to design the library in early 2013, shortly after New York-based designer Rafi Segal was dropped from the job.

The National Library will be a redevelopment of its 120-year-old predecessor.

Herzog & de Meuron said in a statement: “Our project reflects the open and transparent ambitions of the National Library. The strong, sculptural form of the stone – related to the specific topography and context of the site – is elevated off the ground and situated above vitrine like elements.”

The 34,000sq m (365,973sq ft) project will encompass six floors above ground and four floors below. The library will combine several functions: it will be a venue for indoor and outdoor cultural and educational activities; a working research centre; and it will have a hall for digital experiences. Underground, secure strong rooms and a storehouse will be used to hold archives and administrative headquarters.

In a press statement, David Blumberg, chair of the library said: “The new building is the jewel in the crown of the National Library's renewal enterprise, which is moving forward full-speed”. Work is expected to start on-site in 2016, with the opening planned for 2019.

The project will be funded by the Government of Israel, the Rothschild family and the Gottesman family.
