We designed windows in all rooms, as well as LD. A 3LDK square dwelling unit full of openness with a wide span of about 8.6m. A full storage space that takes into account not only capacity but also ease of use, such as walk-in closet and wide entrance storage. Dedicated pouch with a detached feeling that enhances privacy and independence. In addition, we designed a balcony with excellent lighting and ventilation on the side of the Western-style room (1).
