Sharing knowledge and collaboration

At the address Telekom-Allee between Rheinstraße and Hilpertstraße a new six-floor building complex for approximatively 1,300 employees was completed in November 2014 consisting of four building parts with bridges. The Technologie Zentrum (TZ) Rhein Main in Darmstadt is one of Germany’s most significant business and technology parks. Deutsche Telekom is a big player in this modern office park. The high-quality office building provides innovative and pioneering office environment to the business. The new building complex takes into account Telekom’s philosophy of network living and working.

Deutsche Telekom also formulated clear targets for energy concept. The cascade units have now been awarded certification level LEED Gold. The building envelope supplied by Dobler Metallbau has contributed to this outcome.

  • 3,000 m ² metal façade – the majority of which designed as metal ventilated façades.
