Awards, recognition

Première Œuvre – Equerre d’Argent


This project was awarded the Première Œuvre prize, a category of the Equerre d’Argent.

La Première Œuvre rewards the success and skill of a young designer under the age of 40 along with the client who assigned them the project.

In this specific case, the jury highlighted the “good command of timber construction with a short supply chain for raw materials, manufacture and assembly”, and also praised “the generosity of the communal areas” created in this project.

This prize also rewards the client’s “social commitment”.
