In this paper, basic theory for open housing supplied by land leasehold is studied logically. The point of this system is that the dwellers sell the skelton of their building to the landowner after 30 years' leasehold, and that, after then the building will be leased at a low rental. After analyses, the following effects of this system became clear.
1) Affordable housing in the urban areas can be possible.
2) Users can participate in the infill design.
3) Users can continue living comfortably in their old age.
