The Building of the Former Dortmund Bureau of Post, which was built in 1953, has been renovated and repurposed as the new office of the Dortmund Bureau of Health. It has been designed to preserve its historical essence, taking into full consideration the façade, circulation, interior, and more. In a humble and efficient manner, it caters to modern functional and performance needs, including safety, comfort, convenience, and sustainability.

The new Dortmund Bureau of Health is conveniently situated at 9-11 Hoher Wall, offering easy access to the central shopping street within walking distance from the western part of the city. Originally serving as the Dortmund Bureau of Post, the building has undergone meticulous renovation to transform it into a modern, efficient, and user-friendly office space.

The original building was constructed in 1953 and primarily comprises four sections. These include the 8-story A building located on the west side of the site, the 5-story B building connected to the A building, the 3.5-story C building, and the 3-story D building situated on the northeast corner of the site. (The E building in the north courtyard is a newly constructed addition.)

As a historic preservation in Dortmund, the building exudes a strong sense of old times with its fair-faced brick walls and the magnificent French balcony on the D Building. However, it transcends the confines of the traditionalist trend of the 1950s, as the A and C buildings incorporated steel frame structures, which serve as essential elements for facilitating sustainable renovation.

Due to the historical conservation requirements, only minor alterations are permitted in both the exterior and interior design of the building. This presents a challenge in terms of seamlessly integrating modern equipment and facilities while ensuring their compatibility with the original layout and organization of the building.

Through meticulous repairs, the fair-faced brick wall facade not only retains its original texture and simplicity but also incorporates modern equipment seamlessly.

In response to sustainability demands, a total of 450 windows have been replaced with modern sunscreen windows, aiming to enhance natural lighting and improve the energy efficiency of the building. Throughout this process, careful attention has been given to details such as the frame material and window proportions, ensuring that the new elements visually harmonize with the red bricks, thus preserving the building's original historical style.

The main staircase of the A Building, considered a cultural relic, has undergone a protective renovation with an additional fall-prevention net to meet current safety standards. Furthermore, the steel frame structure has allowed two additional new staircases in the A Building, which not only comply with high-rise building regulations but also fulfill specific functional requirements, contributing to the establishment of an efficient circulation system.

Additionally, an old elevator in the A Building has been replaced, a new elevator has been installed in the B Building, and the connection space between the A and B Buildings has been rearranged. These improvements aim to optimize accessibility, particularly by providing barrier-free facilities.

To ensure that the entire space meets modern office standards, the extensive renovations include the complete replacement of the piping system of power and water supply - Approximately 100 kilometers of electricity and communication cables were installed, along with over 1,000 LED lights and around 35,000 square meters of gypsum boards.
