The purpose of this study is building the architecture and the basic motion of a frame element generation system which generates the whole frame element appropriately in timber framework construction house by constituents of a house repeat an adjustment to the mismatching between the local frame elements based on an idea that the consistency between all the frame elements in the house which has been ended design completely is maintained. Specifically, agents that are constituents that extracted from timber framework construction house and implemented functions perceiving surrounding environment, exchanging information with the touched agent, recording those information and generating constituents from the information and the generation rule are put in the site space which is virtual space. The system is a multi agent system that all the frame elements of a house are determined by the agents cooperate and repeat generations and adjustments.
