The exhibit 'Transformatoren-Transformationen' introduces multiple projects concerning the conversion of several of Berlin's former power plants. Built from 1924 to 1930 by the chief architect of Bewag, Hans Müller, the transformer stations were rendered obsolete by the technical advances of the 1980's, and subsequently taken out of operation. The architects Petra and Paul Kahlfeldt, in cooperation with Bewag, have developed several concepts, designed to cautiously address the further utilization of more than forty structures. The exhibit will consist of four examples which are representative of both the different buildings and their disparate functional potential:
The transformer station Leibniz in Charlottenburg has been transformed into the headquarters of MegaDesign AG. After the conversion, these rooms will be used as they appear structurally, adhering to the various functions of the tenant, be they conference rooms, offices, factories, or presentation rooms.
The electric transformer station Zeppelin in Wedding was converted into divisible, unique apartments. The tenants, who include scholars from the Baden Württemberg Art Foundation, can use each level of the different ground plans, each with three support columns.
After minimal reconstruction and changes, the 90m-plus long 'Phasenschieberhalle' of the transformer station Humboldt in Prenzlauer Berg will be used by the Vitra Design Museum for their Berliner Dependance. The oval control room in the courtyard of the building includes further exhibit spaces. Conferences and lectures will be held in the historic 'Schaltwarte.' The powerful 'Schalthaus' is currently under construction, in an attempt to create big, hanging surfaces for the atelier, design and movie companies.
The plans for the transformer station Buchhändlerhof in Mitte are still in their premature stages. Severly damaged during World War II, the building was used as part of the Disco E-Werk and is now being turned into the headquarters of SPM Technologies. In the ground floor part of the building adjoining Zimmerstrasse, flats are being planned in conjunction with the offices of Max Dudler.
