CATERING PAVILION "WOLKE 7"
The concept of a pavilion provided the inspiration for the new construction of the catering zone in the Grafenegg Palace Park. Its experiential potential changes during the year according to scenarios, users and seasons. The “floating” roof covers the open-air zone. The free roof contour continues the lines of the existing stock of trees. Its roof design suggests all-round accessibility to the pavilion, taking effect as an open position in the space. An interplay is generated between the groups of trees, pastoral open spaces, and the design of the roofing.
SYMBIOSIS BETWEEN ART AND NATURE
With a roof that is supported by delicate steel columns and nestles between the trees like a leaf, “Wolke 7” slips effortlessly into the historic parkland of Grafenegg’s castle grounds. The floor of the pavilion is created by the widening of the footpath to form a public space; the interaction between the hard ceiling and the soft ground awakens the feeling that one is entering a room.
The roof of “Wolke 7” is defined by its in-situ concrete surface, which gently rises and falls twice as it translates its natural curvature into a structural principle. Derived from the position of the existing trees this sweeping form of the roof has an additional spatial quality and enables the catering pavilion to open in every direction while drawing attention to the bar as a place where one can linger, protected from the elements.
This double curvature of the in-situ concrete surface was digitally generated via a simulation using silk stretched between supports. The resulting deformation raises the natural shape of the curve to a structural principle. The reduction of the bending stress coupled with the activation of the tension in the membrane creates an economic concrete solution and makes it possible to execute a roof structure of optimal stiffness which requires no waterproofing.
With a length of over 20 metres the counter of the pavilion consists of prefabricated concrete elements with integrated stainless steel cooling drawers and is used both for serving food and drink and as a stand-up bar for visitors to the park. It is complemented by the storage box with serving niches and the plain, sheet aluminium glasses cabinet – a spatial ensemble that is oriented in every direction, free of any sense of front or back.
However, as well as inviting concertgoers to take some refreshment during intervals, the pavilion is also a contemporary architectural object which has become a fixed component of both the Grafenegg Castle Garden and its symbiosis between art and nature. The resulting interplay between clumps of trees, open areas of grass and the design of the roof invites visitors to enjoy unfamiliar glimpses of the surrounding park and the Wolkenturm.
