From 1909 onwards the vast castle was constructed hardly a kilometre away from her paternal residence. The architecture of the facades was inspired by the early 16th century late Gothic wing of the nearby abbey of Tongerlo. A more aristocratic appearance was achieved by adding four small and one large tower, as well as a bell tower in the form of a crown. Although both interior and exterior were executed in a historical style, the building contained many modern features that were very rare on the countryside at the beginning of the 20th-century. The cross-beams supporting the roof were in steel, and the building had electric lighting, an electric elevator, central heating, running water, WCs and bathrooms.
