The former building was previously used as a commercial building and auto parts storage.

The renovation of the original building to become a modern office was introduced by presenting a new enclosure that wrap around the building in a form of material bands that run vertically. Several materials were used in the façade including glass, timber, cement, aluminum, stainless steel, and copper to present a variety of materials in architectural composition.
