The skin of the building has been designed taking into account the varying conditions of lighting into the exhibition spaces, depending on their orientation and height, but also reacting to the potential views of the city from every room. The resulting polymorph geometry of the envelope creates a multiplicity of space types and scales to which the art installations can respond. This will provide the curators, the artists and the occasional visitor the chance to establish continuously new relations between the artwork, the space and the city. Clad with a metallic envelope wrapped with a reflective, dichroic film, the skin of the building will not only express the needs of the spaces to provide certain views or daylight conditions for the enclosed spaces, but also create a polymorphic reflection to the urban surroundings.
