Since the year 2000 Matthew Johnson, artist, and myself, Bill MacMahon, architect and lecturer in the Interior Architecture program at UNSW, have been collaborating upon the incorporation of artworks into buildings. Such multidisciplinary work is having a direct outcome upon my architectural design practice and my work in design studio with Interior Architecture students. As interior architects often work in collaborative teams involving the development of their ideas designs within the work of architects so the work of Matthew and myself might act as a model for Interior Architecture practice. Lessons learnt in the negotiations of changes to architect’s designs can be taught to students of Interior Architecture. It offers lessons in the contextualization of design.
