Survey on Decisions Regarding 'Floor Plans and Proposals' for Custom-Built Homes

Building a custom home is a rare life experience. Consequently, the decisions regarding floor plans and layout strongly reflect the values and preferences of the residents. While full-order homes offer the highest degree of flexibility, semi-order homes, which allow for customization of pre-set templates, are also on the rise.

NEXER Inc., in collaboration with 'IROHA CRAFT,' a renovation and custom home brand in Yamanashi, conducted a survey among 135 individuals nationwide who have experience building custom homes.
