The concept of the redesign of the existing espresso bar in the 2nd district of Vienna is based on the reduction of the existing room boundaries by a chocolate brown coating. The white oiled and brushed solid oak furniture stands out as contrasting elements. The two sanitary rooms kept in sea blue are the only given touch of color. A graphic pattern on the wall of about 2300 (!) various sized boreholes give the café the name katscheli, which means swing in Russian.
