The building is a simple unitary volume composed of two parts. The first four levels take up the entire length of the site, while the shorter upper four create a vast eight-metre-deep recess to the south. These volumes are a response to several clear objectives: creating a simple, unique, identifiable silhouette; constructing a singular skyline that clearly demarcates itself from the banal image of the office block providing a space with potentially collective uses in the heart of the building, with a large terrace and distinguishing two different storey plans. This ensemble of urban and architectural arrangements confers on the building its own volumetric identity and a strong, distinctive image.
