The seven-storey office complex EDGE Suedkreuz Berlin was built sustainably using a modular timber hybrid construction method. The larger of the two free-standing buildings covers around 20,000 m² of floor space, making it the largest wood-hybrid building in Germany in terms of area. The centre of the main building is a light-flooded atrium, spanned by a transparent ETFE foil roof on a wooden truss construction. The central eye-catchers are the four tree-like structures, graduated in height, whose platforms are connected to each other and to the office floors by filigree staircases and bridges. On the fifth floor, the Sky Lounge with panoramic façade and outdoor terrace opens up to the atrium. Wood is visibly found in all interior areas of the building. 

The façades are constructed in a uniform grid of weather-resistant glass-fibre concrete panels. The façade elements weigh only 30 kg per m², are recyclable and have a decarbonising effect. 

In the construction of the buildings, the focus was on reducing the CO2 footprint as much as possible, especially the weight of the complex, and on using sustainable materials that can be recycled according to the cradle-to-cradle principle. The project is registered in the Madaster database and has a material passport that enables the materials used to be reused and recycled. Due to an approx. 50% saving of reinforced concrete compared to conventional in-situ concrete construction, the construction-related CO2 footprint of the ensemble is correspondingly lower. Industrial pre-production (also of the lightweight façades) and the use of wood were essential building blocks. 

EDGE Suedkreuz Berlin was awarded the DGNB Platinum certificate with the highest score ever achieved in Germany of 95.4%, as well as the DGNB Diamond for its outstanding design and architectural quality. WELL v2 Platinum certification is also being pursued.
