In 1672 he made the stucco decoration of the library of Park Abbey near Leuven in Belgium. The stucco relief represents the church fathers and the evangelists as well as scenes from the life of Saint Norbert. In the refectory of the same abbey he decorated the ceiling with seven biblical scenes (1679), signing his work "jan christiaen hansche".
He also worked in several houses and monasteries in Ghent, in Beaulieu Castle in Machelen and in Horst Castle.
A magnificent example of his work are the decorations for Modave Castle. A series of rooms on the ground floor is decorated with scenes from the life of Hercules, while the apartment on the first floor follows the theme of the four seasons.
