Since 2004 work Heribert Wolfmayr (1973) and Josef Saller (1971) – 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.
