In order to realise a modern-day museum function for the Noordbrabants Museum in this former residential palace, the floors have been reinforced and some passages widened. The walls and ceilings now have a hidden air treatment and security system which meets the strictest museum criteria. In addition, a sprinkler system has been integrated. This renovation process required the continuous consideration of technical and functional requirements against the historical values of the original building.

Between the Palace and the newbuild of SMs, the 19th-century monumental building of the former Provincial Registry by architect Van Lokhorst is situated. This now houses common functions such as an auditorium, a restaurant, a staff canteen and offices. The staircase and corridors of the Registry have been completely restored and returned to their original condition. The original colour scheme, too, has been reintroduced after in-depth research. The various spaces have been renovated and fitted with modern systems appropriate to their function. The archive building, formerly part of the Provincial Registry, has been restored and houses the archives of the Erfgoed Brabant heritage organisation and the Provincial Archive of Archaeological Findings. This building has thus been returned to its historic function, whilst meeting modern requirements for use, climate and security.
