For its anniversary celebration, the City of Esch-sur-Alzette decided to develop the banks of the Dippach River, by complementing its park area with five theme pavilions. Our idea was to place a simple, clean volume on columns on the top of the river and adjacent cycling path. The light construction fosters the ephemeral character. The structure consists of frames – flat steels sheets (20 x 200 mm) interconnected with round tubes. This provides a longitudinal stability, while undertaking transversal deformations. A translucent membrane aims to envelope the whole, while separating the inside from outside and thus providing protection. The structure is fixed to the platform, formed by two parallel longitudinal HEA 300 sheets. Light steel columns underneath provide the support for this entire assembly, where their different inclinations absorb the forces. The idea of slim inclined columns comes from interpretation of the surrounding trees. An anti-slip ramp provides an access to the pavilion. The inside is covered with solid wood floor, which together with technical block in same timber contrast the steel benches. During the day, the translucent membrane diffuses the natural light on the inside, whereas during the night it creates a glowing effect on the outside. The design of the structure and the choice of materials allows easy translocation by complete disassembling of its parts. Building with steel allowed extremely thin columns and platforms, thus a very light structure that at the same time provides the necessary stability. Steel has in such a way become the essential material for this project, due to its light structure and quick implementation/transformation.
