“WINX. The Riverside Tower” in Frankfurt/Main is a 110 m high building over 28 storeys, located on the border of the banking district. With its butterfly-shaped and modern architecture, the office tower makes its mark on the skyline and becomes a unique specimen among the city’s skyscrapers. The WINX Tower is designed down to the smallest detail and built with resource efficiency in mind. As proof of this quality, the building received the DGNB platinum certificate.
Susanne Klatten, Germany’s richest woman, acquired the entire building even before its completion in 2019. Many office spaces have been occupied in the meantime. In 2020, the global law firm DLA Piper moved into their new premises on floors 23 to 27 and the roof terrace on the 28th floor of the building. For this renowned law firm, we were commissioned to produce two exclusive staircases.
From floor 26 to 28, an elegant spiral staircase with a parapet railing on the inner stringer and a timeless all-glass railing on the outer stringer is highly convincing. The centre of the stringers is offset to change the running width. A filigree stainless steel U-profile serves as edge protection. Not at least because of the structurally supporting soffit cladding, the spiral staircase gets its sculptural character.
The assembly was really spectacular: already in Salach, our employees divided both staircases into transportable segments, which were placed in the upper floors on the construction site by means of a rotating tower crane. To transport the individual components within the tower, a mini crane was used.
