The BTEK, which houses exhibition premises, is conceived as a reference in the landscape formed by two apparently detached pyramidal volumes. The first one is a black construction that rises from the ground, with a solid composition and enclosed by its three metallic façades, its roof being formed entirely by a grid of solar panels. This position in favour of clean renewable energies is also applied to the rest of the building: geothermal installation, materials, exhibit materials, etc. The second construction, in comparison with the first, is formed by two curtain walls and an Astro Turf roof which was conceived as an extension of the ground. The two volumes are imperceptibly connected underground, blending in with the plot and the surroundings. The entrance takes place through the first construction, where a pleated corner reveals the access ramp. As one descends, a metal projection shelters the arrival, welcoming the visitor in.
