Traditional Japanese townhouses (machiya) integrate nature by placing a garden at the center, fostering a unique aesthetic and respect for nature. A house cannot exist without a physical, abstract, and poetic connection to the sky. This design focuses on living with the sky. A central courtyard is surrounded by rooms, and as visitors enter through a narrow hallway, they are led to the bright, open courtyard. The sky greets them, with light and wind gently filling the interior. The courtyard serves as both a room and passageway, creating a rich living experience beyond its actual size.
