Abstract
The market of detached house for sale faces a great turning point under the change of economic and legal circumstances. And detached houses are expected to contribute to the “community planning”. Under such circumstances, this “Machinami house” design competition was held. The characteristic of this competition is that the inhabitants of the surrounding area, the people who are thinking of buying the houses, and the homebuilders voted in order to chose some plans out of the proposals by the architects. According to the analysis of the voting activities, we found a tendency to prefer the wooden two-stories houses. The significance of this competition is as follows; 1) they had some discussions as an opportunity to promote better understanding with others, and then they selected one plan together, 2) the architects, who haven't been concerned in this market so far, promoted better understanding of detached house for sale and “community planning”, on the other hand, the homebuilders and the inhabitants of the area promoted better understanding of the architects.
