Steel trees with sprawling branches support the glass roof of this greenhouse in Switzerland. Designed by Buehrer Wuest Architekten and located in a botanical garden outside the village of Grüningen, the greenhouse is used for growing subtropical plants such as banana and papaya.
The architects borrowed structural patterns found in nature, like the membranes of a leaf, to create the geometric structure of the roof.
From the architects: 'The new pavilion at the botanical garden at Grueningen relates strongly to its context. The design was inspired by the surrounding forest, not the built environment. Both the formal vocabulary and the structural concept derive from nature. The pavilion is conceived to harmonize with and expand the forest. The geometry of the roof as surrounding membrane was determined by the position of the old and new trunks. The forest was augmented by four steel trees that form the primary structural system of the pavilion. At about five meters, the trunks branch toward the treetop, which forms the natural roof. A secondary glass construction, suspended from the steel branches, encloses the inner space of the greenhouse.'
