Panticosa lies at an altitude of 1,600 meters and is surrounded by the rugged landscape of the Aragon Pyrenees, with mountain faces soaring up around it to heights of as much as 3,000 meters.
The architects working on the project at Moneo Brock envisaged a reinterpretation of the traditional thermal baths that are typical of Panticosa and its surroundings. Their main wish was to construct a building that blends in with the tough surroundings and references them. "We saw this older development of the Balneario as a strange denial of the real situation of the thermal springs in a rugged landscape, and therefore sought from the very beginning to reinsert, or reassert the wilderness of the place; we wished to give the mountain back its voice," the architects explained. In the process, the design they finally came up with consciously references Peter Zumthor's famed thermal baths in Vals. For here, too, aspects such as light and shade, transparency and translucency, open and closed play a decisive role.
Glass and stone are characteristic of the Tiberius Thermal Baths and in combination with these two materials, and first and foremost given the nature of thermal baths, so it water, which, it goes without saying, dominates the interior.
The slightly curved façade is made of glass modules and becomes integrated step by step in the adjoining mountain landscape. The glass modules reflect the light and thus respond to changes in the color of the surroundings.
In the architects' design the range of glass modules „Trapezoidal" designed by Seves Glassblock served to break up the rigid grid of a glass module façade. From the standard shape of a 30 by 30 centimeter glass module Seves Glassblock designed a trapezoidal module, the cross-section of which on one side measures five centimeters and on the other ten. This provides an opportunity, depending on how the form of assembly selected, to design the walls in new shapes and geometry, by combining the edges of equal or different thickness vertically or horizontally with each other. As a result of the overlap of the different modules, "tree structures", or horizontal or vertical curved surfaces emerge.
