The For-sale Housing Project is a new project to deal with the problems that occurred in the Ordinary Housing Project, and which was started using the construction funds for the Ordinary Housing Project. This research clarified the opportunity for the start of the Dojunkai’s For-sale Housing Project and the construction process of the Saitobun Residential Area, which is the first residential area of the For-sale Housing Project. Dojunkai took the applications for Saitobun’s Residential Area in 1928, but Floor plan and others were not popular. Therefore, Dojunkai revised them, and took the applications again in 1929.
