The purpose of this paper is to research how elderly households in TOYAMA-HAITSU live and remodel their space to continue to live there. The results are as follows: The elderly convert two rooms into one by removing the door. They try to make the most of their limited space and improve their house along with their lifestyle changes. The elderly create their working space by removing the household equipments including washbowls. Single elderly households use one of their rooms as storage space because the elderly people generally have many belongings. But on the other hand, other types of households are difficult to create such space. Therefore they eat and sleep in one room. The government provides house remodeling grant for the elderly. But for more effective use of housing stock, the grant for renovation to create adequately sized house which fits their lifestyle is needed.
