The building was acquired by the state for the first time in 1823 when the Brabant Province and the Dutch State bought it to house the Brabant government and act as the official residence of the local governor. This situation continued after the independence of Belgium in the 1830s. Due to development of the provincial government, however, the building became too small and dilapidated by the end of the 1860s. Hence there were successive waves of reconstruction, albeit with a planned design for consistency. The governors residence began to be modified in 1885, and in 1907 the office wing was replaced. Georges Hano, the then-architect for the Ministry of Public Works, built a higher wing with direct access to Rue de Chêne. The different buildings were also interlinked and the facades overlooking the courtyard were unified. The governors residence was increased one story on the side facing the courtyard and the height was also increased on the building surmounting the porch reconstructed by Hansotte. The new / was opened up by the city at the start of the 20th century and Hano desired to make the presence of the provincial government felt on this new road which his complex now bordered. In 1913 works began on a new building, completed in 1930, in a neo-Louis XVI style with a ceremonial entrance hall and lavish decoration.
