Casimir studied Industrial Design at SHIVKV Genk (Belgium). It was never a conscious choice of his to focus on design. Casimir was just looking for a versatile direction that would include theory and technique as well as creativity. While training as an Industrial Designer, he discovered that designing industrial products was not for him, as an industrial product is an accumulation of compromises and rarely the expression of a personal emotion or the personal vision of the designer …

During his studies, he did, however, design a number of items of furniture that expressed his own vision of design. He established himself as a furniture designer and went on to develop this vision into a personal style.
