BRÜHL CITY HALL – HISTORY MEETS A NEWLY BUILT EXPANSION
JSWD refurbishes and expands the heritage-protected city hall of Brühl, Germany
Brühl is a small town near Cologne that is famous for its UNESCO World Heritage castles Augustusburg and Falkenlust. Cologne-based architecture firm JSWD has renovated its heritage-protected city hall, originally built in 1858, and it expanded to include a new building. Made of light-colored clinker brick all the way to the gabled roof, the monolithic structure references the historic cubature of the city hall, creating a stand-alone building in a style typical of the region. The old and new buildings are interlocked with one another at all levels, with both parts merging to form a single unit.
“In terms of historic preservation, it was important for the different generations to remain clearly legible. We achieved this using different colors and materials. We had a lot of leeway in terms of the facade color for the historic building, and we were able to match it with the bricks we had already selected [for the new building],” says JSWD Founding Partner Frederik Jaspert.
The three staggered gabled roofs of the interlinked structures are visible from the street. The new build houses the city administration and municipal library. The children’s library in the basement opens to a reading courtyard.
Jaspert on the interior of the spacious new extension: “We couldn’t house the children’s library on any of the upper floors because the building was already exhausted in terms of height and area. Since the library already expanded over three floors, we suggested putting the children’s library in the basement. While this may sound like a stopgap, in combination with the reading courtyard, it resulted in an extremely inviting interior. And, in terms of the cubature of the building, we were able to remain consistent with the scale of the historic city center.”
JSWD was able to preserve as much of the historic building’s fabric as possible. Energy and heat are supplied by a combined heat and power plant. In addition to triple-glazed windows, a great deal of natural light, and external solar protection, concrete component activation guarantees lower energy consumption.
On the topic of urban repair and connecting the new building to the historic one, Jaspert says: “One key aspect is an in-depth understanding of the location. It’s about adapting to the framework of the historic city center while also keeping up with the times. A building must be accepted by users and passers-by in order to have a long life and therefore be truly sustainable.”
The redesign of the adjacent Janshof transforms its almost backyard-like character into a high-quality, car-free urban space.
Top priority in the competition was the development of a civil engineering and urban planning master plan that was suitable for an inner-city concept.
