Sound wave? Tectonic shift? Mountains? However you read the shape it forms a strong identity for this library that edges up on one side to a wooded ravine.
While its big portico entrance welcomes you inside, only clerestory windows face the rest of town. Along the ravine, however, the building is one continuous strip of window. Beyond being something sculpturally nifty (which it is), the highly angular roof divides the space within into zones for reading, shelving, and enclosure (study booths, multipurpose rooms, offices) while also allowing light from above to make the building glow.
For a smallish branch library, the building is perfect, a straightforward and rectangular layout elevated to be distinct and inviting and cool. Great stuff.
The Capilano Library, another fine work by Patkau architects!
