For the first time the world exhibition Expo 2017 took place in Kazakhstan.
Themed as "Future Energy: Action for Global Sustainability", an exhibition of superlatives is being built on a 113 hectare large site. Large and small objects form a breath-taking ensemble of modern architecture.

One of the smaller pavilions is the so-called "Flower". A canopy for a children's playground in the middle of the Expo area. A small construction, that consists of a prestressed, interrelated curved membrane, which bears on six curved, circularly arranged, two-hinged frames. The outer base points of the steel arches are mounted on individual basements. The base points in the middle on a common foundation. The roof skin consists of a PVC-coated polyester fabric. The membrane lies along the arches and will be stretched downwards by border cables.
