The intention of the Kredietbank (now KBC) when it bought the property was to restore the seventeenth-century patrician residence to its former glory. Although no trace of old plans was uncovered, archives going back to 1532 were consulted and yielded very interesting descriptions of the property upon conveyance. The historical value of the house was assessed by Professor Victor Blommaert and the requisite study was carried out by the architects entrusted with the restoration, J.L. Stynen and R. De Bruyn. The definitive restoration plan was synthesised from the various studies and was approved by the Royal Commission for Historic Buildings and the Landscape.


One of the most difficult tasks was to equip the house with the necessary modern comfort without intruding on the atmosphere of a 17th-century residence.


The original style of the façades and interiors was retained in the restoration. False ceilings and neo-style decorations were removed to restore them to their original state, but alterations considered of value were left intact, in accordance with the generally accepted principles of responsible restoration.


The Rockox House was opened to the public on 20 April 1977.
