After renovating the windows and the roof, the internal walls of the Yellow Hall also required a renovation. After demolition of the plinth trims and unnecessary technical constructions, the renovations included the cleaning and repair of the walls, the uninstallation of obsolete electricity and the partial milling of wall paint. Subsequently, the walls, window and door reveals, as well as the heaters niches, were treated with a mineral inner insulation and painted with a new color. The color was selected based on preservation order and is thought to resemble the former Yellow Hall from 1927. The internal renovation was necessary to meet building climate control demands. In the course of the renovations of the internal walls, 2,000 m power cable and 1,000 m network cable were laid.
