shaping the future – happy new year 2026

What is growing there? When we look closely, we always discover something new: here, a leaf pushes its way out from under a crumb of earth; there, a beetle crawls along.
A beautiful template for wishing you something for the new year. But what? Looking closely? A change of perspective? That would be fitting.

But we want to draw your attention away from the bustle on the other side and focus on its purpose. Because for us architects, greenery is an important building material. A green roof or facade can do amazing things: it insulates in summer and winter, stores rainwater and thus relieves the burden on the sewage system, which – attention, climate change! is important in times of increasing heavy rainfall. In addition, greenery provides habitat for insects, thus increasing biodiversity and improving the urban climate: green spaces cool heated cities, filter dust, and bind CO2. Unlike with concrete, steel, or plastic, there is no need to weigh up whether the use of greenery is worthwhile.

There are only advantages. So you can wish for a small animal zoo on your roof at any time with a clear conscience—Christmas!—or have it carefully planned by your architectural firm. Those who are critical of the costs and effort involved in greening a roof should not only consider the initial purchase price, but also the reduced follow-up costs, the ecological balance, durability, and better air quality. If you factor all of this in, a green roof is worthwhile; it is more attractive and more efficient.

This is therefore not only a plea for green roofs and facades, but also for good, contemporary architecture. We would like to work with you to develop a built environment that is beautiful and healthy, including in the new year. With this in mind, we wish you a happy 2026.

Congratulations, dear Klaus!

Today we celebrate the 85th birthday of Klaus Kada – architect, co-founder of kadawittfeldarchitektur, and a leading voice for architecture with attitude.

His thinking has shaped kadawittfeldarchitektur from the very beginning: architecture as a social task, developed in dialogue, responsible towards the city, people, and the environment. These convictions remain the foundation of our work to this day – from building in existing contexts to sustainable, climate-sensitive solutions.

Dear Klaus, we thank you for your inspiration, your trust, and your courage to always think architecture further, and we look forward to continuing the discourse.
Congratulations and all the best!

Site visit Messe-, Kongress- und Kulturforum Saarbrücken

Burkhard Floors, associate partner at kadawittfeldarchitektur, explained the project “Messe-, Kongress- und Kulturforum Saarbrücken” to the Federal Minister for Housing, Urban Development and Construction Verena Hubertz, the Minister-President of Saarland Anke Rehlinger, and the Mayor of Saarbrücken Uwe Conradt. They also got to see the construction site by our client CSS-Congress-Centrum-Saar GmbH.

The future MKK will bring together trade fair, congress, and cultural offerings under one roof. Our design creates a direct connection between the historic building and a new, polygonal-shaped structure that blends harmoniously into its surroundings in terms of scale and roofscape, yet still develops an independent architectural presence.

The central concern of the project is its close integration with the urban environment. The green axis linking the Saar, Bürgerpark, and city center creates a new network of public spaces – a lively meeting place that promotes exchange, encounters, and cultural activities and has an impact far beyond the region.

Haus der Neugier on WDR-Lokalzeit

We were given the opportunity to give WDR-Lokalzeit a behind-the-scenes look at our Haus der Neugier project in Aachen. The report “Haus der Neugier – DAS ist der Plan” is now available in the ARD-Mediathek.

In the report, Dirk Lange, partner at kadawittfeldarchitektur, and Heinrich Brötz, head of the cultural department of the city of Aachen, were accompanied on a walk through the building.

The Haus der Neugier (House of Curiosity) is currently being built in the center of Aachen in the existing building of the former Horten department store. In the future, the adult education center and the library will form a joint education and meeting center in the converted building. As a “third place,” the building offers space for reading, learning, discussing, and lingering. The demolition of the existing escalators will create a light-flooded atrium with a new, free-standing staircase that connects all levels and promotes communication.
