House Folded, designed by by Kyoto-based architecture practice Alphaville, is a three-story residence in Osaka, japan. The concrete structure sits on a a thin site measuring 80 m². Inside the spatially dynamic volumes, the folded dividing walls are defined by a triangular slit that pierces through its front and rear facades which brings in light and spatial continuity between the indoor and the outdoor.
The spaces are delineated by utilizing the decomposition techniques of a Voronoi diagram which equally divides the shortest distance between points to create optimal spatial segments. The three-dimensional study started from a parallelogram with a center wall that runs diagonally to define two spaces which was then pivoted to run parallel to the site through all three levels. The roof was pulled up to form a slant and a private outdoor terrace. Structurally rational and dynamic, the result is a collection of flowing living spaces that shift and change from every perspective.
