(Headquarters: Nakano-ku, Tokyo; President and CEO: Mitsuo Nagai; hereinafter referred to as "Open House Architect") announces the public release of its "Lifestyle Diagnosis" (Note 1), designed to help customers intuitively find their ideal space tones and resolve the "decision fatigue" often faced when considering room specifications due to an overwhelming number of choices.

Users can simply answer five questions, such as their ideal "travel destination" or "usual shopping habits," by intuitively selecting their preferred options on the screen. This process naturally draws out the user's latent needs, and based on the diagnosis results, the system proposes a matching design from Open House Architect's 102 "Interior Sheets."

By using the "Lifestyle Diagnosis," users can instantly visualize their ideal living space, which is difficult to articulate in words, providing a new home-building experience that is easy, quick, and satisfying.

(Note 1) The "Lifestyle Diagnosis" was created utilizing "C-lab. (Toppan Creative Laboratory)," a research and analysis service provided by TOPPAN Co., Ltd. (Headquarters: Bunkyo-ku, Tokyo; President and CEO: Haruhiko Noguchi; hereinafter referred to as "TOPPAN"). The question design incorporates lifestyle research data accumulated by TOPPAN.

■ Resolving "Decision Fatigue" in Home Building
In recent years, while the spread of social media has made it easier to gather information for home building, many customers face "decision fatigue," feeling overwhelmed by too many choices or exhausted by the numerous decisions required during consultations. To address the challenge of home building becoming a source of stress rather than joy, Open House Architect aims to provide a solution through an approach where "ideal designs take shape simply by choosing intuitively." The company will make this site, which has been in internal operation, publicly available to deliver this "new home-building experience" that allows for the concretization of interiorイメージs from the preparation stage to a wider audience.
