Oskar and Zofia Hansen. Open Form
The exhibition of Oskar and Zofia Hansen’s legacy showcases various aspects of the Open Form theory, which was the axis of their architectural, artistic and educational work.
Presented by Oskar Hansen during the International Congress of Modern Architecture (CIAM) held in Otterlo in 1959, the theory of Open Form proposed to open architecture up to its users and allow them to co-create it. Hansen fought against what he defined as Closed Form, that is fully designed structures leaving no space for users’ creativity and constituting rather a monument to their authors than a comfortable living space. Instead, Hansen put forward a radical change in the perception of the architect’s role which, in his opinion, should consist in creating a passepartout, a background for everyday life. The mission of architecture should be showcasing people and the richness of their daily activity in space. Architecture should highlight subjectivity and create a framework for individual expression, become an instrument that can be used and transformed by its users and that can easily adapt to their changing needs.
The exhibition displays various areas and scales of creative activity in which Open Form was applied. "Background of Events" focuses on designs for exhibitions and pavilions, which offered an ideal ground for theoretical experiments due to their ephemeral character. "Politics of Scale" focuses on Oskar Hansen’s urban planning projects, displaying their socio-political dimension. "The Individual in the Collective" treats the Hansens’ realized residential estates in Warsaw and Lublin, presenting their lesser-known, often unpreserved details. "Architecture as an Instrument" focuses on designs for public buildings: museum, gallery, theatre, recording studio - whose shape was to be determined by the users. "Active Negative" shows the private space of the Hansens and the concept associated with them of sculptural presentation of architectural interiors. "Anti-monument" describes the space-time design for the "Road" memorial to the victims of Auschwitz-Birkenau, a group work that became the sculptural reflection of Open Form. Exercises from Hansen’s studio at the Faculty of Sculpture at the Warsaw Fine Arts Academy are mixed into parts of the exhibition. Hansen taught at the academy for 30 years, promoting the tenets of Open Form among his students.
