High above the rooftops of Frankfurt shines the bold and purist architecture of the office and conference floor of DVB Bank, awash with high-quality details from a holistic design dominated by glass and a careful blend of white and grey tones. Entrusted with the demanding task of restoring the 40th floor of City-Haus, Frankfurt architects Theiss have created an environment for meetings and conferences that sets a new benchmark for modern working applications. The unusual axis dimensions and reduced installation depth placed special requirements on various features of the project, including a pioneering customised lighting solution that has now been integrated into the standard MIREL evolution product family.
