Built by Fuensanta Nieto and Enrique Sobejano with a horizontal frame, the Convention Centre has a wave-like roof with skylights to allow sunlight to enter illuminate foyers and common spaces. Likewise, the rooms receive natural light from outside by means of translucent façade walls, in alternating stretches of glass and metal latticework. The white glass fibre reinforced concrete roof enhances the thermal insulation properties of the building. The brilliance and clarity that will typify the building during the day will be transformed at night into a landscape of solid light emerging from the terrain with the light being projected outwards.

The final part of the exposition "Water, unique resource" takes place in a partially covered, 200 meter long space in which the importance of considering water as a human right is presented, in order to respond to the water crisis and the inequality it causes. Along this extensive space three different experiences are found: an element with different refractive elements and audio programs which present water as a basic necessity for the satisfaction of certain human rights, a series of audiovisual and interactive experiences which underscore the importance of considering water a human right, and a wall of water which invites visitors to sign, expressing their support for declaring water a universal human right.
