In the developing world, skills in innovation and creative design have emerged as key attributes for graduating designers. Creativity is essential if we want to generate new solutions to the considerable and complex problems in architecture. Metaphor is frequently expressed as a key tool for enhancing creative design, yet little empirical research has been performed on how novice designers can use it within their design. The goal of this study is to empirically research the use of metaphor in the design studio, with a focus on its effects on design creativity and quality. A three-stage method is presented, which allows novice designers to use meanings and metaphors in the early stages of design and idea generation. This method was tested in an architectural studio with two groups as experiment and control groups. The results were evaluated using a qualitative research methodology and a questionnaire was prepared in which the students were requested to assess the use of this method in their design process. Also expert designers evaluated the design outcomes in both control and experiment groups. The results highlight that metaphor is a helpful tool for young designers to stimulate design creativity and has a noticeable effect on design quality factors such as novelty, value, flexibility, usefulness and detail. These research findings have different implication for novice architects and help them enhance creativity and quality in their design endeavors.
