The project respects the value of the ancient thermal baths on which it is built, setting the solid, petrous character of the existing in contrast with the lightness of the new; a glass piece that organizes the space between the hotel and the baths. 

The original roofs are reconfigured by means of floating platforms that let sunlight enter through the sides, and the use of a raised floor guarantees greater spatial fluidity, being at level as it is with the outdoor pavement.
