Formally, the Chilean pavilion has been outlined as a bridge made of laminated pine wood whose wooden, reticulated structure is trusted with the expression and formal synthesis. It is a regular volume that is supported by 6 steel pillars, each with 3 arms. This allows us to liberate the noble floor by creating both a visual transparency and the free stroll of the visitors. This strategy establishes a close relationship between the urban space and the pavilion space, narrowing and fusing the line that has been drawn between the private and the public. Constructively, we have set out a kind of Meccano where the simplicity and rationality of the system allow to quickly assemble the pavilion and to dismantle it and take it back to Chile. The idea is that the system and its assembly respond to constructive tradition proper of the material with half-wood, thus, diminishing the amount of ironwork. The main structure is constituted by the reticulated beam that is located in the line of the metallic pillars. The exterior beam provides the pavilion with tridimensionality, and it also helps to balance the building. The wooden, reticulated structure appears from distance as a totality (monumental scale), while the fragment appears in the closeness (quartering of the wood) that relates us to the body and gives the pavilion a human scale, making a resistance strategy out of the tectonic and handcrafted when opposed to the seduction of the vain spectacle. The Pavilion’s interior has been developed as a neutral space easily adaptable to the programmatic demands that will reach high relevance after the Expo, considering the likely recycling of the building.
The main goal of the Chile Pavilion is to show millions of Expo visitors this country’s extreme geographical diversity: from the Atacama Desert to Patagonia, and from the central green valleys to the eastern islands. These very different regions are described through their ecosystems and how these ecosystems are being preserved. To house this concept, the Chilean architect, Cristián Undurraga, has designed a suspended structure covering almost 2000 m2. It consists of a large wooden lintel enclosed by a frame of criss-crossed beams and supported by four concrete pillars that create an intermediate space.
The access point is a relaxation area with tables and benches in which the visitors encounter the Chilean “dinner table,” with all its flavours and colours. A group of red statues, modelled on Chilean farmers, indicates the path to follow. Visitors reach the suspended wooden structure by means of a central ramp that takes them into a multimedia nucleus featuring a tunnel with twenty-four synchronized spotlights that offer visitors a virtual reality experience.
The lighting project is the work of the Chilean lighting designer, Maite Zubicoa, who has opted to highlight the wooden façade and ground floor ceiling only. In the remaining space there is no artificial lighting given that images of food and their geographical origins are projected continually, as if it were a cinema. At night the structure looks like a huge lantern lit only from the inside. The pavilion’s wooden framework is lit by iPro spotlights positioned in the individual triangular cells of the structure, and a warm colour temperature was specifically chosen by the designer as it is particularly suited to wood. Maite Zubicoa also selected non-invasive luminaires that blend into the architecture while also highlighting its shape and form.LED lamps were used to reduce consumption levels, and significantly, only 20KW/h is required to light the whole building.
The Concept From the Atacama Desert to Patagonia, from its central green valleys to its eastern islands, extreme geographical diversity will be a key feature of Chile’s showcase at Expo Milano 2015. As a main attraction, the pavilion takes visitors on a journey to experience its different ecosystems, deserts, rivers, valleys and mountains, showing how life grows and is preserved in each of them. Chile offers evidence of its pursuit of balance in a multitude of landscapes, cultures, foods and geographical landmarks that are unique in the world. Its aim is to entertain visitors, to promote an interest in its land and to demonstrate a commitment to its protection of water resources and sustainable food production for all. The main material used is wood, reminding us that the forest area of Chile is increasing, in contrast with the continuing deforestation on Earth.
