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.
