The underground room is part of a pre-existing building dedicated to cultural and religious meetings and located on a hill near the city of Alba. Three long gashes offer direct natural illumination to the underground room. These gashes are placed along the main sides of the rectangle, covered by a vault of successive arches that function as the base of the construction. The source of light is when the sun is directly overhead. This mirrors the spiritual intentions of the meetings that take place in the room.
The anti-vibration soundproof system is achieved by the use of perforated wood acoustic panels placed on the ceiling and, partially, on the walls.
