The sub-station was originally full of machinery transforming electricity to power the Prague tram system. The modernized technology allowed to free up the whole building by compressing the equipment into a small part of the underground.
The technical condition of the neoclassical building from the 1930s was critical. Internal load-bearing concrete structures were contaminated not only with oil and mercury, but also with the meanwhile prohibited alumina cement. These structures showed after 80 years wrecking parameters and had to be removed. The conversion preserves the original external building envelope. Facades and roofs are restored to their original status. All preserved characteristic elements are professionally restored.
Two additional structures express from outside the new public function of the building:
- The entrance to Kunsthalle is built on a footbridge, which arises from the sidewalk to the elevated entrance hall at the piano nobile level .
- A new gallery space, replacing the obsolete air handling equipment on the roof terrace. The cubical extension is hidden from the main street behind the pith roof structures. From the back street it complements the principle of a receding rugged facade.
Inside the building a new spatial concept is introduced. All spaces are evolving on different levels in the sense of a “raumplan” which logically reflects the existing neoclassical window pattern. By using bash hammered architectural concrete we visually follow the materiality of the original industrial building.
Kunsthalle offers to the public three large gallery spaces, a conference hall, a book lounge, educational spaces for children, a design shop, a bistro, and a café with a terrace that features views of Prague Castle. Basements are used for exhibition preparation areas, workshops for restoring art works, depositories and technology placement.
