Two great steel arches lift and rotate around a central axis pulling a polyester/pvc fabric which at the same time inflates and pulls up the other smaller arches until it reaches the shape of a big pneumatic shell. The gigantic shell measures 15 meters in diameter, inflates in 7 minutes and more slowly deflates – pressed by the steel casing – thus causing the return of the two arches to their original position. At the end of the operation, the presence on the ground of a building is hardly noticeable whereas the telescopic equipment is free to turn for 360 degrees and from horizon level to zenith.
