In order to display the length and galleries of CDC Menor, reflective reflexes and knots that were built into the granite of the cladding and railings were developed. It was necessary to solve the problem with the "wet laying" of granite. On the sides of the gallery are carved from the stone historical facades of the buildings of the city. They were illuminated from above, showing relief. All standard equipment had to be installed in non-standard places with non-standard functional values for it or to develop individual lighting devices.
