The rooms for special exhibitions are connected directly to the foyer and to the new exhibition spaces for the permanent collection. Administration, the Metzler Auditorium and the library are re-located to the west wing. The new space for the art of the second half of the 20th century is located in the ‘garden halls’ beneath the Staedel garden. The central room is dominated by an elegantly curved and seemingly delicate ceiling with circular rooflights. The curve in the ceiling emerges above ground as part of the new garden’s topography, like a piece of land art, and can be used as an outdoor extension to the foyer. The compact underground building form, the method of heating and cooling, the pre-warming and pre-cooling of air and the large internal storage mass together create an optimal room climate with minimal energy consumption.
The jury said of the winning design “A shining jewel at daytime, a carpet of light at night – with this design the architects have achieved something extraordinary.”
