Abstract
Standing on an assumption that development of house construction depends upon the popularization, it is important to define the process. From the point of view, this paper picked up four factors ; quality control for materials and components, diffusion of new technique for professional and laymen, structural design standards, and condition of labours. The author got the conclusion from this research, as follows ; The British Standard influenced the quality control, because of it's long history, never stopped at the war period. The popularization of new technique developed with the state policy, supported by advisory committees. The establishment of structural design related with engineers preference, in case of steel, and traditional system retarded progress, because of accustumed method. The problem of labours was a key factor for not only traditional method, but also innovational. Finaly, it should be said that the contribution of the state acted very important role in this field.
