An existing Art Nouveau building on the Brussels inner ring road was converted into the headquarters of the advertising agency Duval Guillaume Brussels. The fact that large parts of the building were classified as a protected monument placed specific demands on this renovation. For example, the glass dome over the atrium is one of the largest domes of its kind in the world. Despite these specific requirements and restrictions, the works went smoothly resulting in a successful transformation into a stylish office building where it is pleasant to work.
