The office building in Düsseldorf known as “The Cradle” was completed in 2024 by project developer Interboden and is regarded as an innovative building. In accordance with the Cradle to Cradle® principle, it was designed as a hybrid construction, which reduced the ecological footprint. When dismantling the building, there is virtually no waste. The construction materials used result in a 47% reduction in CO₂ emissions compared to conventional buildings. In addition, a further reduction in CO₂ emissions of 38% is achieved in operation. This optimization was developed early on, as the BIM model was linked to a Circularity Passport® building for the first time and as a result, CO2-intensive components were identified and more sustainable alternatives could be replaced in a targeted manner.
The façade of the building is characterized by its diamond-shaped structure, which gives it an unmistakable and characteristic appearance. The eye-catching laminated timber supports can be dismantled again at a later date to enable further use of resources. Depending on the direction of the compass, they are arranged at different depths and therefore function as passive sun protection.
To ensure that the air quality in the interior is completely free of pollutants, we have installed PVC-free carpet. During the day, it filters particulate matter out of the air, and in the evening, the dust is simply sucked away. Planting the walls on all floors also helps to keep the air clean.
