The Kiosk is located in the Park of the
Bundesgartenschau in Potsdam,
Germany. As an
extension to an existing café it is selling ice cream, lemonade and coffee.
The environment of the park was basis of the
conception to work with a natural unrefined material. This material itself
should define the design of the kiosk and provide the structural support.A kiosk
is a small, separated garden pavillion open on some or all sides. In the Islamic culture it was constructed by rough
tree trunks that supported a roof made of straw or wood.The kiosk was designed in a close collaboration with
structural engineers. Different structural systems were simulated with the computer.
Willow branches
have been woven to a surface. By reducing the buckling length and by diagonal
bracings the wall has been reinforced and is stable. The joints of the branches
have been connected by wire-tying, in order to keep them from shifting.The inner shell of the kiosk is made of multi-wall
panels and has no structural function. It protects the interior from water and “catches”
the shadow of the woven willow branches.
