The purpose of this study is to reveal the attitude of people, who are considering purchase of a house, toward having a private garden and its quality. To confine study objects, we handed out questionnaires in a housing exhibition, and to obtain answers similar to the situation when they actually buy a house, we made a questionnaire using the conjoint analysis that can make examinees consider tradeoff. As a result, we found that when people buy a house, they place more emphasis on whether there are some facilities such as a hospital, a school, a commerce facility and a public park close to their houses, and less emphasis on having a private garden. Moreover, we found that when people make a private garden, they place more emphasis on the time and labor for the maintenance of a garden and less emphasis on the characteristics of a garden: for example, whether various creatures can live in the garden. And it also becomes clear that a person who has a garden desires a garden in his/her new house and that the age of people affect their awareness of a private garden.
