The Isumi Villa, designed by Takeshi Hosaka Architects, is a vacation residence located in Chiba Prefecture, Japan, adjacent to the Isumi River.
A defining feature of the villa is a 45-meter-long concrete wall that serves as a spatial and visual backdrop, integrating the structure with its natural surroundings.
The design prioritizes outdoor connectivity, with interior zones like the kitchen featuring a dirt floor to maintain permeability between inside and outside.
The architectural strategy supports a program centered on outdoor living, emphasizing environmental awareness, spatial openness, and material restraint.
