This study focuses on homeowners opening their property to the public at Open House London. On the basis of questionnaire it finally reveals their motivation and role. Close cooperation between a homeowner and an associated architect made a decision of participation and hosted many visitors by providing a guided tour, etc. Homeowners fully understood an organizer’s concept “quality of architecture design” and took a responsibility of educating citizens instead of aiming at gaining economical or social benefit or regarding it as an opportunity to start something new. Such a homeowner in fact has repeatedly participated, which makes this program attractive.
