The restoration of the historic building on Hohenzollernstrasse, designed by Unterlandstättner Architekten, is a refined intervention that seamlessly blends heritage preservation with a contemporary architectural language. The project is grounded in a deep respect for the original structure, enhancing its proportions and construction details through precise material and technical restoration. The historic façades have been meticulously preserved, safeguarding the authenticity of the urban fabric, while the interiors have been reimagined with a contemporary sensibility defined by openness, light, and spatial fluidity.

The introduction of new architectural elements, such as the windows and doors crafted with the W75 TB painted steel system, allows contemporary functional requirements to be seamlessly integrated without compromising the building’s historical identity.
The new frames provide excellent thermal and acoustic insulation while preserving the original architectural character. The slender steel profiles respect the building’s proportions and detailing, allowing natural light to flood the interiors and elegantly frame views of the city.
