Klunkerkranich – Membraneroof
We designed and constructed the new membrane roof for the Klunkerkranich cultural roof garden in collaboration with Stoffdach. Its location high above the rooftops of Berlin placed special demands on the roof.
The roof terrace, which is used for catering purposes, required a roof structure that would allow maximum flexibility of the usable space, would not obstruct the unobstructed view of the city with supports or guy wires, and would keep the required escape routes completely clear. Conventional tent-like structures were therefore out of the question.
Our design is based on the principle of an umbrella with a central mast and cantilevered support elements. It is based on the existing structure of the bar building and spans the terrace via a central high point and two additional smaller high points. The covered area of around 140 m² requires only two additional masts, apart from the beams arranged along the building. The high points are formed by three air supports, while the curved membrane edge is tensioned by cantilevered beams.
The roof thus ensures unobstructed use of the terrace and an unobstructed view into the distance.
