This residence serves as the lifelong home for a couple who have completed child-rearing and now cherish everyday living. The second floor, designed as the heart of daily life, arranges the living and dining areas to envelop a southeast-facing terrace.
The terrace is conceived as an indoor-extending outdoor space, enclosed by perforated roofs and walls, enabling the inhabitants to engage with nature while maintaining privacy from surrounding views. It functions as a spatial device that enriches daily living by fostering an intimate connection with the changing seasons.
On the first floor, a fully soundproofed music room serves as a workspace. The interplay of the music room’s floor level difference with the second floor, the living room’s atrium connecting to the third floor, and an observation terrace that captures the verdant western landscape, collectively create a wooden three-story residence characterized by spatial diversity and continuity.
