The paintings by this artist, who also worked as an architect, are abstract and have no object right from the start; however, they are by no means lacking in form. The material properties and intrinsic value of the colours and surfaces are central to his artistic inspiration. Gerhard Lojen's early abstract material works placed him among the ranks of the most important founders and representatives of abstract painting in Austria after 1945.

Die Malerei des bildenden Künstlers, der auch als Architekt tätig war, ist von Anfang an abstrakt, gegenstandslos aber nicht formlos. Die materiellen Eigenschaften und Eigenwerte der Farbe wie auch der Fläche bilden zentrale Parameter seiner künstlerischen Ideenfindung. Durch seine frühen abstrakten Materialbilder zählt Gerhard Lojen zu den wichtigsten Begründern und Vertretern der abstrakten Malerei in Österreich nach 1945.
