Hoffmann studied architecture at the University of Vienna with the famous architect Otto Wagner. After completing his studies he spent some time in Italy. The Italian country house, cubic, whitewashed, with windows carved irregularly out of the walls inspired his first architectural works. Like many of his contemporaries, Hoffman wanted to create a complete work of art: "I believe that a house has to be made from one piece and that its exterior should reveal its interior. His highest commitment was to the "permanent quest for better materials and the effort for an ever more perfect representation". His style was characterized by simplicity, integrity and precision. His designs were characterized by clear forms and geometric ornaments.
