Fuma House

Fuma House

Fuma House is an award-winning residential architecture project located in Fukuoka Prefecture, Japan, designed by architect Masakatsu Matsuyama of Matsuyama Architect and Associates, representing a sophisticated architectural response to challenging urban conditions through innovative structural engineering and spatial design strategies. This three-story reinforced concrete residence for a family of four addresses multiple environmental adversities including proximity to a heavily trafficked railway line with approximately 250 trains passing daily, exposure to noise and vibrations, flood risk from historical severe water damage, and adjacency to a declining urban quarter that once flourished during Japan's modernization era. The architectural solution employs a distinctive cantilevered design where the second floor extends 5.6 meters toward the street and 3.2 meters toward the parking area, achieved through the strategic implementation of two and three-story high load-bearing walls reinforced with two unbonded post-tensioned cables along the east-west axis, complemented by a symbolic U-shaped wall that assists the southern cantilever. The eastern facade incorporates a complex-profile configuration with the first-floor wall set back from the railway, while second-floor structures and third-floor eaves create a layered defense against noise, vibration, and unwanted street views, with carefully calculated gaps between these elements permitting natural light penetration and external ambiance while maintaining acoustic and visual privacy. Fuma House demonstrates advanced principles of defensive architecture through its reinforced concrete construction, which provides structural resilience against both seismic activity and flood risk while simultaneously creating thermal mass for climate moderation in the humid subtropical environment of Fukuoka Prefecture. The spatial organization prioritizes the second floor as the primary living level, designed to function as a single-story dwelling within a three-story structure, featuring a living-dining room that connects vertically to a third-floor theater room through a double-height atrium space, establishing both sectional and planar axes that integrate interior and exterior environments. An east-west sectional axis extends from the first-floor courtyard to the third-floor terrace, while a north-south planar axis connects the second-floor southern terrace to the northern stairwell, creating diverse spatial experiences and multiple relationships between built form and landscape. The integration of vegetation throughout the architecture, including gardens and terraces, represents a deliberate design strategy to soften the massive concrete construction and create transitional zones between interior and exterior spaces, allowing the residence to maintain an open lifestyle without curtains despite its urban context. The project encompasses a site area of 510.86 square meters with a total floor area of 464.76 square meters distributed across three levels, with the second floor comprising the largest area at 238.40 square meters to accommodate the primary living functions. Large glazed openings face the internal courtyard, extending interior spaces toward semi-open external areas and creating visual connections across multiple levels, while the carefully orchestrated sequence of solid and void, opacity and transparency, establishes a sophisticated environmental control system that filters urban disturbances while maximizing natural light and ventilation. The architectural language of Fuma House reflects contemporary Japanese residential design principles that emphasize the relationship between interior and exterior spaces, the integration of nature within built environments, and the creation of tranquil domestic realms within challenging urban contexts. The design process, spanning fifteen months from June 2021 to August 2022, followed by a seventeen-month construction period from September 2022 to January 2024, demonstrates the complexity of realizing such an ambitious structural and spatial concept. The residence enables its occupants to begin each day on the terrace among plants, enjoying coffee in an open-air setting despite the proximity to railway infrastructure, with children utilizing the full spatial volume by running freely indoors and sharing visual connections across the atrium, exemplifying how thoughtful architectural design can transform seemingly unlivable conditions into enriching domestic environments. Fuma House received the Platinum A' Design Award in 2025 within the Architecture, Building and Structure Design category, one of the world's most prestigious design competitions, recognizing works that stand at the forefront of creativity and innovation, acknowledging designs that blend remarkable innovation with impactful societal contributions while showcasing exceptional artistic and technical proficiency. The Platinum designation represents the highest accolade bestowed by the A' Design Awards, celebrating designs that are truly exceptional and demonstrate unmatched professionalism and the uttermost genius of their designers, with recipient works expected to be magnum opus creations that define the aesthetics of an era and contribute to societal wellbeing. The architectural approach embodied in Fuma House reflects Matsuyama Architect and Associates' design philosophy of interpreting the potential of specific sites to guide unique architectural forms and family lifestyles that can only exist in particular locations, with each project involving different land, clients, and conditions resulting in diverse solutions that would not be possible under different circumstances. The residence exemplifies how contemporary architecture can address multiple environmental challenges simultaneously through integrated design thinking, combining structural innovation with spatial sophistication and environmental sensitivity to create residential environments that enhance quality of life while responding to specific contextual conditions, representing a significant contribution to architectural discourse on urban residential design in challenging environments.
