Revitalization of a Traditional House in Obama|Tetsuya Kimura Architects
《Revitalization of a Traditional House in Obama》
This project involved the renovation of a traditional house built in 1879. Constructed with fine timber and a high level of craftsmanship, the residence had been passed down through generations, undergoing several alterations and extensions over the years. However, the spacious earthen-floored entrance hall at the center of the south side of the house, together with the adjacent south-facing room with its magnificent exposed roof structure and boarded floor, was hardly used. The children's room that had been created on the second floor along the south side had also become vacant, as the children were now adults. Including the two adjoining Japanese-style rooms used for ceremonial occasions, the two-generation household had been living modestly in the peripheral areas and outbuildings, avoiding the main parts of the large traditional house. The interior floors had numerous small level changes, while the entrance hall, with a children's room above it, had an extremely low flush ceiling that prevented it from being effectively used by adding a floor.
The primary objectives of the renovation were the effective use of space, improved protection against the cold, replacement of decayed timbers, and structural reinforcement. The house was considered as two zones, north and south, with the floor levels organized and aligned within each zone. The former south-facing entrance was floored and converted into a living-dining room at the center of the house. The second-floor children's room above it was removed, reducing the oppressive low ceiling while allowing light to pour in from above. The Japanese-style room adjoining it on the north, which retains its original floor height, and the living-dining room are connected by a difference in floor level between floor seating and chair seating, bringing the sightlines of the two spaces into alignment. The newly redesigned partitioning shoji screens feature a horizontal band of transparent glass at eye level, suggesting the movement of sightlines between the spaces. From the living-dining room, the view extends through the Japanese-style room to the garden on the north side.
The former boarded-floor room, with its magnificent exposed roof structure, was unsuitable for use as a living space because of the severe winter cold, so it was revived as a distinctive entrance hall. Composed of square timbers, it is a space where darkness is accentuated, in contrast to the bright, light-filled living-dining room. A ceramic roof ornament in the shape of a crane, which had protected the house from atop the roof for many years, was displayed so that it emerges in the indirect light cast upward from the floor. Colored washi paper was placed at intervals in the shoji partition leading to the living-dining room, adding a subtle touch of color to the austere, dark space.
