The bureau greisch has won the restoration tender for the Collégiale Notre-Dame in Huy, alongside the architects Binario and La Croisée.
The building, which harmoniously combines the radiant gothic style of the 14th century and the flamboyant gothic style of the 15th century, is listed as an exceptional heritage site in Wallonia.
The great glass roof of the choir is made up of three parts, each an impressive twenty-two metres high.
