The existing five-storey building dates back to 1996 and it is characterized by its symmetrical shell and its monumental character. The total remodeling of the facade and the interior of the building aims to highlight the contemporary capabilities and to reinterpret the architecture of the past. The prior dense grid of the glass panes is replaced by impressive wide single glazing that reaches the maximum permissible height and length, leaving the view outwards unimpeded. The notions of completeness and emptiness, of light and shade, coexist in a harmonious whole of geometries and volume. Furthermore, unexpected views between indoors and outdoors, along with the element of slim openings, summarize this rhythmic change and outline the view. Horizontal elements, like single balconies and canopy, unite the two sturdy parts of the existing shell. The canopy at the ground floor welcomes the visitor to the building, while the canopy on the roof forms the coronation. In this way, the sense of consistency and succession of the distinct members of the building is completed. An open-air atrium is situated at the heart of the building, in response to the search for a “natural oasis” in the contemporary workplace. The built parapets on the roof are replaced with glass material, offering views to the Faliro Bay, within a natural environment of landscaping that covers the roof.
