"Frei Otto and Rolf Gutbrod attempted, with this competition-winning project, to create a man-made landscape. The cavernous interior contained modular steel platforms arranged at different levels. The entire area was covered by a single membrane of irregular plan and varying heights. Its contours were determined by the high points of the masts and the low points where the membrane was drawn, funnel- like, down to the ground. Eye loops filled with clear plastic material accentuated these points and the saddle surfaces they created. The prestressed membrane consisted of a translucent skin hung from a steel wire net, which, by eye, ridge, and edge ropes, was connected with the mast heads and anchor blocks."
