The proposal includes a new 3900–square meter exhibition space in front of the existing building with moveable slabs and an elevatable roof, which can be adjusted according to program. This ultra-modern mechanical system allows for interaction between the exhibition space and the city: the roof can be lifted to give the gallery a direct physical connection to the street level. Meanwhile, by eliminating a superstructure to the extension, the architects have given deference to the existing building. The intervention also includes a plan to refurbish the historical gallery to reveal its original brutalist form.
Situated in one of Poland's most culturally vibrant cities, Bunkier Sztuki is a rare icon of Polish brutalism. Since its founding in Planty Park in 1965, the gallery has undergone several alterations, including a cafeteria pavilion directly in front of the exhibition space. The planned restoration will eliminate all unnecessary additions and return the building to its initial intent.
