The building is a listed building. It is also part of an urban monument area. This building is one of the most elaborate and architecturally most important palaces of justice of the Wilhelminian period. Inside and outside are numerous architectural decorations in the style of late Gothic and early Renaissance. The main staircase is designed as a steep, domed hall.
The overarching goal of the preservation authorities was to reconstruct the building's appearance in the exterior and in selected areas.
The focus was, on the one hand, the restoration of façades, windows and doors as well as on selected publicly accessible rooms, in particular on the entrance area and the main staircase, stairwells, hallways and some negotiating rooms which were to be updated with the required modern furnishings and technical equipment.
