Recently, our action against global environmental concerns including global warming is high priority issue. Then an energy saving, effective use of the resource, the reduction in the construction waste and the reuse of the material are important problems in the architectural production field. In a word, it is necessary to review the architectural production method. The authors are researching the timber house rebuilding system that uses the used structural members again. This rebuilding system dose not apply the steel joint to raise the reuse rate of wood members. To facilitate the construction work, the demolition work and rebuilding of the timber house, a built up system with continuous beam is adopted. The case study house was constructed to clarify the effectiveness of this system. In this paper, the outline of this rebuilding system, the results of construction, demolition experiments and re-construction are described.
