In Cologne, Thomas Fehlhaber from Lebensraum Ziegel, Konstantin Jaspert from JSWD Architekten, Alexander Gutzmer from Baumeister and Anja Koller from “Topos” and “Garten + Landschaft” discussed growing cities, the housing shortage, the construction boom – and the role of bricks as a building material in this interplay.
As part of Baumeister nach8, we discussed an archaic building material and its role in modern residential construction with JSWD Architekten and Lebensraum Ziegel in Cologne.
It’s back, it never really went away: the brick. The building material, which is thousands of years old, has succeeded time and again in becoming a talking point through innovation. Brick can certainly be modern – and today it takes a counter position to the euphoria of 20th century steel and glass architecture. The panelists at the Baumeister nach8 event questioned the brick in a larger, contemporary context: more and more people are moving to the cities, living space is becoming scarce – especially affordable living space. One possible solution is to move upwards. But isn’t a steel structure better suited to this than brick?
Thomas Fehlhaber, Managing Director of Unipor and co-initiator of the Lebensraum Ziegel project, takes a different view: seven storeys are perfectly possible with brick. “Brick has changed over the past 30 years. From a – to put it casually – normal brick to a highly technical product,” he says.
More high-rise buildings, more apartments – that raises concerns in urban society. Resistance to construction projects is now coming from many quarters. Konstantin Jaspert, founding partner of JSWD Architekten, is uncritical of the building boom. He presents himself as an advocate of enclosed space. In his opinion, there is still sufficient capacity to densify cities. Jaspert quotes Hamburg’s senior building director Höing: “We need density. If we want to continue pursuing the European city model, then we have to allow it.” Jaspert is directed against generalizing building opponents: “You also have to accept that a wall of houses is being built next door.” The counter to this is that stubbornly raising walls without foresight is detrimental to a healthy urban climate. Sustainable, climate-optimized construction is in demand – today more than ever. And this also works well with brick, says Fehlhaber: “Brick construction is sustainable and economical. The natural capillary system inside the brick has a moisture-regulating effect and creates a pleasant and healthy indoor climate.” Bricks compensate for large temperature fluctuations and store heat, which in turn saves heating costs.
Bricks are not only practical, but as a natural product they are also authentic, develop a naturally beautiful patina and score points for their combination of homogeneity and individuality. Depending on the format of the bricks, the joints and the masonry bond, bricks can give a house a rustic, expressive or modern appearance. Diversity is therefore a given, but architects and builders must also make the most of it: Konstantin Jaspert criticizes the uniformity of “white plaster boxes in the ‘Bauhaus style'”. One should not be satisfied with mediocrity. In this respect, the panellists emphasize the creation of identity as well as the cultural and regional classification of the material. Each city has its own face, its own language, which needs to be recognized and understood. While the façades in Munich are plastered, the clinker brick façades in Hamburg gleam rust red. “We want to build new today, but we also have to deal with our architectural history,” says Fehlhaber. Then an authentic blend of old and new can be achieved.
The fact that architects are planning with brick is a sign of sustainable building, as demanded by politicians and scientists. A step into the future with a tried and tested building material that has been rediscovered and that brings architecture, which has become alienated in some cases, back down to earth.
