YNAS Revitalizes Traditional Japanese Home with Open Concept and Corrugated Metal Canopies
YNAS, a distinguished local architecture firm, has embarked on a remarkable transformation of a classic timber dwelling situated in the scenic southern region of Japan. This ambitious project involved not only a comprehensive renovation but also the addition of strategic extensions, ingeniously incorporating corrugated-metal canopies to redefine the living experience. The primary goal was to cultivate a more expansive and connected interior, seamlessly blending the home's various spaces with its natural surroundings. This revitalization was undertaken for a couple who, after significant life changes, chose to return to the wife's cherished ancestral home in Miyakonojo, intending to reside with her father in a dwelling that now embodies both tradition and contemporary openness.
This thoughtful redesign by YNAS not only modernized the internal layout but also enhanced the external interaction of the residence. By introducing new structures and materials, the architects successfully bridged the gap between the indoors and the outdoors, promoting a lifestyle deeply intertwined with the natural landscape and the local community. The integration of traditional elements with innovative design principles has resulted in a home that respects its heritage while embracing a forward-looking vision, providing a harmonious and self-sufficient environment for its inhabitants.
Transforming Traditional Living: Open Spaces and Community Connection
The House in Miyakonojo, originally constructed in 1978, presented a unique challenge: a structurally sound timber house with a confined internal arrangement and underutilized outdoor areas. This design deficiency led to a disconnection from the picturesque landscape and the vibrant local community. YNAS addressed these issues by meticulously reimagining the home's boundaries, removing restrictive walls and hedges to create an expansive, flowing interior. The traditional engawa, or verandahs, were extended and deepened with elegant steel and timber canopies, transforming previously neglected spaces into functional and inviting areas. A notable addition is the outdoor kitchen, which not only provides a contemporary cooking space but also offers breathtaking views of the surrounding mountainous terrain, effectively integrating the natural beauty into daily life.
Yuko Numata, the principal architect and founder of YNAS, emphasized the project's core directive: to balance family privacy with community engagement. Rather than erecting barriers, Numata adopted a paradoxical approach, creating a design that subtly reveals signs of life within the home. Neighbors can observe the family enjoying the outdoor kitchen or spot smoke from the wood-fired bath, fostering a sense of connection without compromising personal space. This innovative strategy re-establishes the house as an integral part of the landscape, allowing its daily rhythms to resonate with the community and the natural world.
Integrating Heritage with Modern Sustainability
The original layout of the home featured a conventional design with rooms separated by sliding screens, all branching off a dimly lit, L-shaped corridor that distinctly partitioned the living area from the kitchen, dining room, and bedrooms. YNAS radically altered this configuration by eliminating the corridor and all interior partition walls, forging a unified, open-plan living, dining, and kitchen space. Distinct zones within this expansive area are now subtly defined by the structure's original timber columns and varied floor finishes, creating a harmonious flow while maintaining functional separation. New timber-framed canopies, adorned with corrugated metal, now provide shelter for the engawa spaces adjacent to the entrance, dining, and living areas on the south side, and the kitchen to the north.
These canopies serve a dual purpose: they extend the home's unusually shallow eaves, providing essential shade, and effectively transform the previously under-utilized perimeter spaces into seamless extensions of the interior. Numata highlighted the redefinition of Japanese ambiguous boundaries through carefully selected floor materials. Mortar doma floors now continuously link the kitchen, dining, and eave spaces, reinforcing the indoor-outdoor connection. Conversely, the living room and the father's room feature tatami mats crafted from authentic Kyushu igusa rush, allowing residents to experience a tactile connection to the land. Traditional elements like a kamado wood-fired stove in the outdoor kitchen, an irori sunken hearth in the indoor kitchen, and a steel wood-fired bath in the wet room were thoughtfully reintroduced. Firewood for these features is stored in a low gabion wall made from local rubble, which replaced a hedge, discreetly obscuring views from the road into the living room. Furthermore, a new timber-framed storage area clad in corrugated polycarbonate sheets, with an accompanying steel and timber canopy, now shelters a parking and outdoor workshop space to the northwest. The home's modernization also included a self-sustaining strategy, featuring the installation of solar panels on the roof and a sophisticated rainwater harvesting system.
