FILTER ARCHITECTURE is a group of young architects in Sarajevo, who gathered in 2009 after winning first place in the competition for the 'Historical Park of the Medieval Bosnia'. So far, the group has been working on various projects of architecture and won several prizes. The group is organized nonhierarchically, while insisting on the exchange of opinions. The work on the project seeks to question a given problem, while design is understood as a certain type of research. Thanks to this approach, the process of harmonization of attitudes becomes FILTER to create quality.
