**■ Experiences of "Regrets after Building" and "Success Points" by those who built custom homes**
While custom-built homes offer the freedom to decide floor plans and facilities, it is not uncommon for people to feel "I should have done this differently" once they actually start living in them.
There are things that only experienced people understand, such as inconveniences that couldn't be seen just from looking at blueprints, or regrets about not fully anticipating future changes in lifestyle.
Therefore, in collaboration with "Smiful Home," a construction company for new and custom-built homes located in Isahaya City, Nagasaki Prefecture, we conducted a survey on "regrets after building a custom home." The survey targeted 164 men and women nationwide who answered "I have built a custom home" in a preliminary screening.
