The decision to divide a large office space into two buildings made it possible to achieve an intimate, friendly working environment. Alternately offset office floors allowed the scale of the building to be reduced. Jutting out corners shield the internal courtyard from the nearby expressway. Extensive full-height glazing provides excellent lighting conditions in the interiors and greatly increases the absorption of solar energy. Internal louvers are provided to improve the energy balance of the buildings. The elevations form a large-size composition consisting of protruding strips of cornices between floors, made of composite panels on which large rectangles of windows are sitting. The massing of the elevation results from office space shading analyses and takes into account the mutual relations and proportions between buildings. The concrete used in the interiors and rough surface of the cast-in-situ floor are contrasted with the delicate grid of stainless steel ceilings and white glass.
