Revitalization of the renovation of the exterior facade of the administrative building of the Liberec City Council - called URAN replaces the original facade of the lightweight exterior facade of the so called Boletic panels (1967) with a facade with today’s thermal insulation standards, with a view part made of hot-dip galvanized sheets.

The proposal for the renovation of the perimeter cladding follows in principle on its original solution. It does not change the small scale of the composite parts of the cladding, it maintains the same ratio between the glazed and solid parts of the facade, it keeps the same proportions of windows and a significant horizontal division of the facade. The design also follows the original tectonic composition system. However, thanks to a different facade cladding material, the overall impression created by the house changes significantly.

The surface of the facade is divided by the shadows of cornices, by windows, but also by individual pieces of sheet metal, joints between them, the grid of anchorages. The surface of the galvanized parts flashes in the light, the reflections differ in each plate. The house reflects and changes the changing light of the surroundings.

At the same time, the facade solution works with different depths of detail corresponding to the distances from which the building can be seen. Significant horizontal division and URAN inscriptions are visible at a distant view when arriving from the city center on the street 1. máje, when passing the highway from Prague and Zittau.

New topics are: the emphasis on the entrance to the building and the peculiarity of creating a unique building from an indifferent 1970s office building. A building, which reacts to the specific situation.
