The striking feature of this library building is the undulating roof structure. The clean, open and uncluttered architectural expression is realised through a post-tensioned concrete structure utilising the inherent longitudinal stiffness of the concrete waves, a concept which took the client and checkers some time to appreciate.
The structural engineers convinced the client by demonstrating the building techniques, thereby instilling a feeling for how the structure would be stable. The result is a ‘floating’ concrete roof which delights the local community.

Judge's comment:

The structural engineers on this project used geometry and stiffness to best advantage in order to realise a concrete roof which appears to defy gravity. This is only possible through a profound understanding of the engineering – relating to stability, load paths, structural form, materials and construction.
