Cube Berlin
19th May 2020

Cube Berlin is an 11-storey, 19,000 square-metre office building in the Europacity urban district of Berlin, with a double-skin façade using a combination of GUARDIAN glass said to change its appearance depending on the viewing angle, the weather and time of day.

Olivier Beier Costa, Guardian Glass Sales Manager who worked on the project sais: “The biggest challenge was to combine two things: first of all, the design and aesthetic concept of the architect and secondly, the technical requirements of the building, so we had to identify the right products that could be used for such an application. That involved the performance of various tests and calculations, as well as the production of many samples.”
Materials used included:

• Guardian SunGuard HD Diamond 66 Ultra and SuperNeutral SN 62/34 solar control glass.

• Guardian ClimaGuard Premium2 thermal insulating glass.

• Guardian UltraClear low-iron float glass.

Torben Østergaard, partner at 3XN and architect on the project added: “Our initial idea was to sculpt the building so that it would enter a dialogue with the urban space, the surrounding buildings and life at Washington Platz. In order to make the building work as a sculpture on the square we were looking for reflective glass that emphasises the surface while also visually reflecting the surroundings.”
