The interior design transcends the traditional typologies of closed office and open office. Places of work and study and areas of relax and interpersonal relations are here mixed, helping meeting opportunities among people. An appropriate use of lights and colours, obtained through the recourse to stained glass creates different places suitable for the various uses of the building: workplaces as well as convention and exhibition areas. In such an open and relatively informal place, made complex by the presence of more activities, the institutional signs become a basic element for the direction of the different visitors that attend the centre.
