In July 1901, the Slupsk City Board proposed a construction of a new building in the city centre to the District Council. The council approved the proposition and settled a budget of 66 000 marks for purchase of building plots on another meeting. The building was to be put up at the corner of a street running straight forward from the market to the old town and the riverside path. In the second half of the 19th century, courts, a forest district office, a bank, a pharmacy, a high school and restaurants were situated at the Slupsk boulevard. Preparations for construction of the new building were being made quickly, a one-floor Rehfeldt's forge with a half-timbered construction was pulled down, a house belonging to the von Krock family in Armia Krajowa Street (Wilhelmstrasse) was to be kept and joined with the new building.

The building construction was designed by Berlin architect Karl Bel. On 8th April 1902, it was officially approved by district administrator von Schmeling and, in less than one month, Bauamt in Koszalin gave permission for the works. Before the first frost came up, a traditional topping-out ceremony was held. Efforts to place all necessary equipment inside the building were started in the spring of 1903. On 6th November, the building was formally given for use. A total cost of purchasing the lands (possessions no. 227 and 228), constructing and equipping the building reached 313 300 marks. Celebrations were held in a carefully decorated large meeting room of the District Council. The building was an important spot in the city since the very beginning.

The building plan is similar in shape to the U letter (the southern, western and northern walls) inscribed into a square. It has basements and the socle reaches 2 metres above the level of the building all around it. External parts of stones used for the construction were given a slight processing and were joined with plaster paste. Stones in corners, stair steps and window lintels were made from grey granite. The outside walls were made from high-quality red clinker bricks. The paste joints were slightly moved further back than the wall face and all decorative elements were made from sandstone. Architectonic details were based on Renessaince and Flemish-Baroque patterns. The western wall facing the Slupia River features a particularly beautiful architecture.

In the south corner of the western wall, a tower 33,8 metres high was put on. In the top part of the tower, a clock with the face 2,5 metres in diameter facing 4 directions of the world was placed. Above, you can see a tall spire with the air vent. On the tower spire and on the tower in the western facade, you can see rhomboidal sheet copper that has remained up to now. The rest of the roof was covered with galvanised sheet metal. The attic roofs are hidden by 5 pediments. In the western facade, a wider pediment has a projection moved 5 metres further forward than the wall face. In the past, it was decorated with Prussia's emblem and a figure, but now there is a decorative Slupsk's crest. In the bay window under the windows, a vase with cut flowers is put on and, in the tower between narrow windows, you can see symbols of knightly families and an owl (a symbol of wisdom). On the southern wall, we can find two plates: a one with hunting symbols and the other one with fishing symbols. On the southern projection, closer to the tower, a shield with Ustka's crest is located; crops and farming tools – symbols of the Slupsk area – are right next to it.

As for rich interior design, three rooms deserve your particular attention: the Słupsk district administrator's room, the Red Room and the biggest one – a meeting room on the second floor. The administrator's room has walls covered with panelling up to the half of its height and a ceiling with elegant beams. Before the Second World War, that was a place where portraits of district administrators hung. The Red Room – in a wing parallel to Armia Krajowa Street – was used for official meetings. Its name comes from a dark-red colour of wall tapestries that have not remained, unfortunately. The most spectacular and beautiful place is the meeting room on the second floor. There is a historic chandelier being a gift for the district administration office given by the city that is a symbol of good relationship between the country district and the municipal district. The room was decorated with stained glass windows given by owners of land properties and two actual-size symbolic figures supposed to make public servants remember to always act within the law and truth. Unfortunately, the old design did not remained and the room is decorated now only with lintels and the district's crest and flag.

After the Second World War, the building was a place where a head office of the district authorities was located until 1975. Between 1976 and 1998, the province authorities and later the region authorities used the place. Since 1st January 1999, when district authorities were established once again, the building has played its primary role. In 2002, the pediment and the tower were given night lighting which was agreed on between the city authorities and the historic object conservator.
