wood-framed family home in osaka revolves around flexible open sports space
the free space accommodates sports, play, and everyday activities, and can be quickly reconfigured.
Flexible ‘free space’ adapts to sports, play, and family life
Osaka House by SHIOYA DESIGN is a two-generation residence in Japan organized around a large, flexible open space known as the ‘free space.’ Initially conceived as a dedicated judo area, the space developed during the design process into a gymnasium-like room that can accommodate multiple sports, play, and everyday family activities.
Rather than assigning a fixed function, the free space can be adapted to changing needs and interests. Judo, basketball, golf, bouldering, and other activities take place within the generous volume, with ceiling heights calibrated to different sports. A retractable golf net, basketball hoop and court markings, and bouldering wall are integrated into the room. Loose-laid tatami mats can be rearranged, allowing the space to be reconfigured in around 15 minutes.

‘free space’ connects Osaka House’s interior and exterior
The open volume also forms a visual and spatial connection with the surrounding living areas. A shared kitchen and dining space brings the two generations together, while a second-floor living room and rooftop terrace overlook the free space below. Gardens and additional outdoor areas extend the house beyond its enclosed rooms, while planting around the perimeter provides privacy without fully separating the residence from its surroundings.
Completed in 2025, Osaka House by SHIOYA DESIGN Studio is a wood-framed residence of approximately 183 sqm. Its undefined central space provides a flexible framework for movement, exercise, play, and shared activities, allowing the domestic layout to change over time.
