A new way of thinking is shaping the way we work and where we work. All in an inspiring environment that combines sustainability with smart technology. EDGE Suedkreuz Berlin – Vattenfall's headquarters in Germany since August 2022 – exactly embodies this spirit. A building that fits perfectly, both outside and inside, into the world of tomorrow. Why not be a part of it?

Winners of the Sustainability Challenge

Sustainability Challenge Gewinner




Out of three finalists, two winners have made it to the implementation phase.

After invigorating ideas and promising pitches for the Sustainability Challenge, circular economy startup Ecobean and carbon capture startup Sally R will implement their solutions at EDGE Suedkreuz, Berlin. Both companies went through a thorough co-creation phase with the project team from EDGE, Vattenfall and Urban Impact where they have discussed the business plans and the technical implementation of their solution. Hours of brainstorming, feedback giving and testing resulted in excellent final presentations.

We will be able to experience their products when the building opens its doors next year. These 2 teams will be awarded a budget of up to 100.000 € to implement their solution.

The Timeline

The Building

The essence of modern working: The spectacular building ensemble, developed by EDGE, is intelligent down to the smallest detail – starting with the emission-saving wood-concrete hybrid construction. When completed at the end of 2021, EDGE Suedkreuz Berlin will be the largest wood hybrid building in Germany. Behind the clear architecture of the Carré, there is plenty of smart technology for the efficient operation of the building. Inside: maximum freedom to flexibly design room concepts flooded with light. The absolute highlight is the atrium, with a roof that offers an unlimited view towards the sky. Filigree open staircases run at different heights through the inner courtyard – supported by tree-like columns.
