Due to the complexity and size of the project, the architects opted for a large, grass‑covered roof.
The roof adapts perfectly to the topographic, climatic, and environmental constraints, and contributes to the continuity of the landscape.
Structure
A roof of 393.7 ft x 262.4 ft covers the interior spaces where terraces and pools are arranged on different levels. The roof supports have a distance of 95.1 ft in some locations; the cantilevered beams can reach up to 55.7 ft in length.
Due to its location, the calculation of snow loads and the seismic design were particularly important.
In order to withstand heavy snow loads and seismic variations, the construction consists of a network of crossed truss girders with a static depth of 6.6 ft and four locations above which shells open to the south, providing the necessary light for the interior rooms.
Furthermore, two pedestrian bridges have been built to connect the roof with the surrounding mountains.
