The hearth center is configured as an S that “tie” the remains of two medieval walls in the place, preserving and even enhancing their role in the environment. It takes place on one floor for reasons of management and circulation, configured as a volume which folds and works looking for the maximum natural light. The building is formed by a series of skins that become more opaque in some areas to provide them more privacy, but also uses lattices to allow the views in public areas.
