In the magical basement of the former Gabriel Loci monastery in Prague 5, we prepared an ethereal installation full of fragrance, smoke and sacred atmosphere. It was for the presentation of the new Yard washbasin collection for RAVAK. Its main motif was a kind of concrete altar. The central positioning within the columns and vaults was key to its very form. The wall thickness of the concrete body was only 10mm at the edge, i.e. in frontal view the whole concrete structure was very fragmented and delicate. The concrete arches are subsequently used in other RAVAK displays.
