He has recently started writing about the architectural projects that catch his imagination. Conversion of the Bornemann High-rise into Jobcenter Berlin-Mitte in Germany by Rüthnick ArchitektenMarch 14th, 2019 by Sumit Singhal
Article source: Rüthnick Architekten The extension of the town hall from the 1960s in the Müllerstraße, in opposite to the Leopoldplatz, was converted by Rüthnick Architekten and technically as well as energetically updated to the latest technological standards. A special influence on the plans for the transformation of the listed ensemble was the preservation of the draft character of Fritz Bornemann. Between 1964 and 1966, according to the plans of the architect Fritz Bornemann, a twelve-story high-rise and an upstream single-storey annex were built, which, at the time, served as the district council hall (BVV-Saal).

The judgment of the jury in 1955 was: “The urban development in the large green area south of the old town hall is excellent.” BAUWELT 1955, No. 44, page 891. Taking into account the Bornemann design, Rüthnick Architekten adapted the energetic upgrade of the facades, the modernization of the building technology and the fire protection, as well as the floor plan structure to the space requirements of the new users. Structurally and in terms of energy efficiency, the 50-year-old building complex no longer met the current requirements and had to be extensively repaired and rebuilt for its new use as a job center and vocational information center.

When renewing the washed concrete slabs, the existing light parapets and the dark opaque outer wall surfaces of the window bands were designed as smoothly cleaned surfaces, in consultation with the monument protection authority. For reasons of carrying capacity of the existing structure and economy, this intervention had to be made in the protected facade. At the same time, the window elements, taking into account today’s energy and building physics requirements, were completely renewed, according to the original model. Inside the building, all walls made of exposed masonry remained in the hallways. They were repaired and cleaned in the course of the construction work. A new color concept is the basis of the design of public areas and corridors.

The suspended 60s ceiling and wooden wall coverings were dismantled and re-installed originally after improving the fire protection. By adhering to future-oriented energy standards, the building fulfills the requirements of the Energy Saving Ordinance (EnEV) 2014. The conversion and interior renovation has created a striking example of preserving a building from the post-war modern era.
