The area south of Tennoji Station in Osaka City is called Abeno. Before World War II, from the Meiji to Showa periods, it is said that the hillside east of Tenga-chaya Station featured photogenic ponds and parks dotted with high-end restaurants and tea houses. Today, almost all of it has been replaced by apartment buildings and houses. Fortunately, one large garden and residence remains in a narrow alley of Abeno, and a family has taken it over to live there. The mansion retained traces of its construction using precious materials and high craftsmanship, such as complex roof structures, massive beams, and thick floorboards laid in a radial pattern. However, several renovations had connected the main house to the Kura(storehouse), added a reception room and hobby room, and caused various issues with the structure, waterproofing, circulation, and views.We designed the space to resonate with both classical Japanese styles and materials, and modern living and functions. Floorboards and shelves were carefully removed, their surfaces planed down for reuse. Many shoji screens and sliding doors were repaired, repositioned, and reused. The additions and detached structure were removed to improve waterproofing, structural integrity, and daylighting conditions.The dining kitchen and living room were placed at the center of the high-ceilinged main house, enabling seamless access to the Japanese-style room, Kura, bathroom, entrance, and wooden deck. Several circulation paths were created both inside and outside, expanding the flexibility inherent in traditional Japanese houses.
