Since 2004 work Josef Saller with Heribert Wolfmayr heri&salli- out spatial drafts, architectural horizons; they work with interventions, bound with surroundings and landscapes which reach their targets in materiality compared with people. By opposites, put into interlinked connections, an architectural idea - as a collection of different substantial barriers and surfaces reaches its concept and necessity in connection with material, open space and human being. Man as active being always is the reason for possibilities of architectural drafts.
