The three domed greenhouses, with acrylic glazing and filigree aluminium framed support structure, were built in the late 70s at the Botanical Garden of the University of Zurich. The structures have been updated with structural and energy-related restorations. After removing the acrylic glass, the aluminium structure was restored where necessary, cleaned and then reinforced with cables. As replacement for the 2,500 m2 acrylic surface, a special designed glass system with ventilated double glazed acrylic elements were used. The three domed display houses have different heights from 9.5 m to 17.0 m and a diameter of between 21.6 m to 26.8 m.
