UHPC façade panels with star-shaped perforations have been used for a public facility on the Sion plateau.

The panels measure 2 m x 3 m and have been made with polystyrene inlays. They are fixed to the framework of the building with concealed ties made of brackets and threaded rods in stainless steel.

"We opted for UHPC because we wanted to combine the thickness and compactness of the material with a transparent effect. Also, it has a soft and polished texture and a deep solid colour. The possibilities of use are infinite, since this is a material you can work with. We look forward to doing business once again with Fehr. As an architect and specifier, it is the first time I have worked directly with a manufacturer and I have found it very stimulating, because you feel you are creating a unique object, and that is actually the case. Usually, we work with finished products that are totally standardised. As an architect, I have enormously enjoyed this feeling of craftsmanship, making something to measure, getting off the beaten track."

A facility integrated into its environment: the stars of Sion

The façade is made of panels with star-shaped perforations. That original motif comes from the fragments of stone lilies – fossilised marine organisms called sea lilies or crinoid – that can be found on the site and in many places in Lorraine. These creatures have been around for over 200 million year, and live in colonies attached to the bottom of the sea.

With that repeated motif, the construction has become part of local geology and history.
