In a subtle interplay of tradition and innovation, the structure's façade features robotically cut Jura limestone. This design choice is a respectful echo of the site's historical Gründerzeit buildings, providing a aesthetic connection to Frankfurt's rich architectural tapestry. The architectural design by TEK TO NIK Architekten imparts the interior space a visual depth: oversized glass elements, strategically placed behind the stone, accentuate the natural stone façade.
