A large number of joints are developed as a result of various timber construction techniques, structural efficiency and cultural differences. Many joints are not used because they are not adapted or are inconvenient for modern manufacturing and construction technologies. Nonetheless, this construction heritage can be harnessed and adjusted for contemporary use. Significant cultural and social differences in timber jointing and construction technologies are reviewed. The Geometric Breakdown Method is developed to analyse the geometry of timber joints for structural, carpentry and construction considerations. Using this method, traditional and modern joints can be understood better and designers can use accumulated construction knowledge to create new joint designs in a systemic manner.
