located on the outskirts of aurillac’s city center in france, brisac gonzalez architects has completed a multi-purpose hall forming a venue for theater, concerts and sporting contests. named ‘le prisme’, the flexible and readily adaptable design employs retractable seating and a demountable stage, and is capable of accommodating up to 4,500 people. never permanently occupied, the scheme is a chamber hosting a variety of ephemeral events.

the structure is defined by three stacked ribbons of concrete which vary in height and texture, and delineate the three separate zones of the building: entry, hall and back of house facilities. this also creates a series of residual spaces which contain services, machinery and technical access. the upper volume is made from prefabricated concrete panels with a grid of glass bricks. during the day, sunlight interacts with the 25,000 bespoke prisms, producing glimmering effects and dramatic shadows. in the evening the structure comes to life as the surfaces of the bricks amplify the intensity of the lighting scheme, resulting in a glittering façade.

internally, a 12 meter tall space forms the main hall, a column-free volume which measures 40×60 meters. a large door ensures that trucks and other service vehicles can enter, delivering performance and catering equipment or trade shows displays.
