Interior and exterior designs stem from the art. Nevertheless, such design is being conceptualized as architectural design. Various materials have been supportive to climax a piece of architecture in which clay is one of them. Its versatility had evolved a new three dimensionality decor in pedagogy of ceramics in this study. The research is advancement in the art of ceramics technology where the use of clay is made possible in the production of 3-dimensional 'art-decor' installed as coverings on building surfaces such as: pillars, wall arc, and window frames. Ceramic clay-arc-d?cor aims to impart hands-on experience to the teaching methodology of ceramics which is essential to the minimum standard in teacher education. The research employs practical application of tools and materials to fabricate; manipulate and construct finished product. The end product is fired in terra-cotta. The study took place in the Department of Fine and Applied Arts, FCT College of Education, Zuba-Abuja in conjunction with the Ushafa Pottery Centre, Ushafa Bwari Area Council FCT Abuja. It was discovered among many recommendations that the use of clay on architectural building will reduce the burden placed on the use of cement hence improve local content consequence upon improvement of Gross domestic product.
