Paul died in 1952. Lina stayed in the house until her death in 1969. Suzanne, the only daugther of the couple, inherit the property which she sold ten years later to Guy and Léona Dessicy. Despite being listed, the building was deteriorated. The new owners undertook restoration works which lasted fifteen years. The original idea was to host a Tintin museum. The project, which had already been approved by Tintin’s creator Hergé, was later abandoned and the Dessicy family decided to convert the former cellar and kitchen into an exhibition space.
