LA based french artist Sebastien Leon Agneessens developed the idea of sound sculptures, spreading through a skyscrapers several teraces, floors and commonly used rooms. all floors should play different sounds the artist had created. from his musical pieces up to the sound of the streets of istanbul. the project was presented at the 100% design show in london, and on the mippim in cannes, before the final sculptures were developed and installed at the luxury residence of nef163 built by autoban architects in istanbul. the project was called "golden horns". from the first drawing of the artist onwards, we developed the sculptures, the exhibitions in london and cannes, our team built up the sculptures with the whole electronic equipment and installed the final version on site. besides the original solid brass worked sculptures, we developed a high quality pvd coated stainless steel tube system, which was used to keep the material durable to external exposure. the sound system is reaching over hundreds of meters through the building - from the reception to the rooftop studios, playing a different art piece of SebLeon at all locations.
