The basic idea was to suggest simple but strong sensations. Being slightly suspended from the contour elevation, the building seems to project out of the ground, giving an appearance of both bulk and lightness. Two large spaces were planned within the plot but outside the construction: a large patio running off the atrium, and a small square linked to the commercial zone. Such as an analogy to a city block, the building incorporates multiple different scales, from large-scale integration in Parque das Nações, to the intermediate street scale that continues on the inside space of the square, up to the human scale of those who live it. The architectural planning of the regions of most significant area were resolved in the subsoil (the lighting of these spaces is controlled through patios), distributes the open-office spaces per two east-west oriented nine floors bodies, occupying the margins of the plan. The structure has a concrete base that is an integral component of its total image, when seen both from the inside and from the outside.
By not reaching the ground, the huge concrete wall on the west, allows us to visualize the Pavilion of Portugal at the height of the avenue. In order to guarantee the sense of continuity achieved between the patio and the small square, the street traffic was plunged under the proposed square via a tunnel. This channel also provides access to parking areas and loading/unloading bays. The pedestrian access is concentrated in the main entrance off the building, alongside D. João II Avenue, making the atrium the departure point for accessing all the different parts of the office block. Built like a glass box, allows you to view the grand courtyard of the building and the water mirror that creates different optical illusions by reflecting the upper floors.
A Curtain wall system has been adopted for the façades, alternating aluminium and glass to reduce optically the scale of the building, creating its own particular identity. This also provides a pleasant internal work environment with decent lighting and worthy panoramic views. Great importance has been given to the to the folding vertical outer shutter patented by Lorenzon, which has the function of manually regulating the internal lightning intensity for each work station, thus creating irregular shapes on the outside which, combined by the other elements, complete the desired architectonic characteristics. Through a PLC system, one has complete control of the opening and closing of the blinds, up to making the façade completely blank. The set of volumes and the effective combination of materials such as concrete, aluminium and green shaded glass, balance an intended appearance of both weight and lightness.
