In this paper, we introduce a new method of wooden house-construction named as P-WooD system using wooden panels, which is improved from traditional log cabin construction. With this development, it is possible to make a new wooden house design never seen. We developed the system by using wooden panels in order to make construction of houses simple, and this system can provide the more variety of arrangement of rooms than the traditional one. We discuss the novelty of proposal models with the P-WooD system.
