The existing office building is a traditional cellular office with large indoor atrium. The new environment has its shape, zoning and routing obtained by the implementation of organic prefabricated cocoons. In addition, several working spheres arise, such as team work and concentrated work. The prefabricated cocoons facilitate units for phoning, concentration areas and informal and formal consultation rooms. The enclosed spaces in the cocoons are covered with insulation and felt. Outside the cocoons working zones are created with various flexible workspaces.
