Telefónica is a leading private company in the global telecommunications market, with
headquarters in Spain. Recently, Telefonica Group has built the District C site, the new
Telefónica’s central headquarters.
In order to identify District C quickly as the new Telefonica headquarters, it was decided to use
corporate branded signs with the Telefónica’s logo. The branding of the entire complex will be
achieved with 5 signs.
Due to the architectural singularity of the building, built with glass facades, it was not possible to
build the signs with letter shape using an aluminum front face as it was very heavy to hold to the
glass. Besides this it would have had a poor looking at night as they would have had to be
illuminated with external light projectors.
With 3M technical support and advice, a solution has been provided using different films, resulting into a
metallic look during day and white look at night with transmitted light.
