The project

Winner of the Prix de la Ville de Versailles, the Biosphère building exemplifies the meeting of architectural audacity and structural mastery. Its curved silhouette, wrapped in a convex glass façade, houses a sports hall and retail spaces within a sculptural, light-filled volume.

Mathis designed and built the glue-laminated timber frame; a structure of arches and beams with variable curves, where the challenge lay in the millimetric precision of the joints and their seamless dialogue with the glass envelope.

On a highly constrained urban site, Mathis deployed its full expertise to combine technical rigor, architectural fluidity, and structural accuracy. Conceived as a work of detail as much as of structure, this project unites formal innovation, technical excellence, and a deep sense of place. A true contemporary landmark where wood reveals its full constructive strength and modernity.

Wood has crafted our story.

It gives form, ignites the imagination, and uncovers meaning. With Mathis, wood takes on a language of its own.
