This refurbishment of Pregnana school Auditorium was designed to give its 110 seats maximum comfort for both eyes and ears. A wooden acoustic new shell was added within the existing perimeter in order to absorb sound along the walls. A new zig-zag ceiling was added to make the speech and music travel to the end of the hall without loosing its quality, and in order to hide the air conditioning services. A new big window was open on the left side towards the school garden, making open air show also possible by turning the armchairs of 90 degrees.
