A circular steel ring with a diameter of 12m is covered with a two-layer ETFE membrane, formed as a cushion by means of the necessary air pressure. In the outer border area, a fine rope net consisting of 20 round-strand ropes lies on the upper side as well as on the lower side of the cushion.
This gives the desired form to the cushion - namely as a lens - and also keeps it in shape.
In addition, the effect of a lens is intensified by the choice of the colour of the material and purposeful lighting.
For the outer border area a white less translucent membrane is used. In the centre of the circle, in the area of the more pronounced convexity of the lens, a completely transparent membrane is selected, which allows the visitor to look from the bottom to the top or from the top to the bottom, and have an outlook to the forecourt of the hotel.
