The O’Siyam Pavilion is a multi-purpose outdoor structure designed to accommodate outdoor performances, art exhibits, yoga classes, awards ceremonies and community events. A change room and small green room service the stage.

The structure occupies the south end of a municipally owned property which includes an existing sculpture garden and the Squamish Arts Council building. The structure is split into 2 metre grids of undulating waves inspired by the locale where the mountains meet the ocean.
