Exhibition of Lifestyles Seen Through Architectural Models and Meetings to Consider Future Living Held

Yamahon Co., Ltd. (Headquarters: Tamano City, Okayama Prefecture, Representative Director: Yoshihiko Yamamoto), through its housing brand HARELYA premium, will hold a pre-opening event combining an "Exhibition of Lifestyles Seen Through Architectural Models" and "Meetings to Consider Future Living" at "omotecho HOUSE B," a new space opening in Omotecho, Okayama City.

How to Choose a New Lifestyle, Seen Through Architectural Models At this event, 10 architectural model works (model plans that can actually be purchased and built) will be exhibited, selected from a total of 244 residential plans submitted to the "Setouchi International Architectural Design Competition" held in 2025. Visitors can consider housing from the perspective of "what kind of lifestyle to choose" rather than "what kind of house to live in," while experiencing the architects' philosophies through the models.

"Lifestyle Meetings" for Dialogue with Architects During the event period, talk sessions and interactive events with architects participating in HARELYA premium will be held. These provide a venue to consider the ideal way of living in the future, while engaging with architects' thoughts and design philosophies.
