alphaville: house folded

kyoto-based architecture practice alphaville (kentaro takeguchi, asako yamamoto) has sent us images of ‘house folded’, a three-storey residence for a couple in osaka, japan. exploring methods of creating distinct and individual rooms that break away from a monotonous spatial experience, the design pleats the dividing walls to form optimal and dynamic volumes of space.

standing on a slim site measuring 80 m2, the concrete structure translates its angular character to its facade, featuring asymmetrical slices in its facade. both the east and west facade is defined by a triangular slit that introduces light into the interior while providing an outdoor-space-like effect through  a system of floor-to-ceiling glazing. a sheltered parking space for a single car is also created by excising an irregular opening from the street.

the delineation of space utilizes the decomposition techniques of a voronoi diagram, equally dividing the shortest distance between points to create optimal spatial segments. the process, which required the full use of a 3D model, started from a parallelogram with a center wall that runs diagonally to define two spaces. this partition was then pivoted to run parallel to the site as it continued to the third level. 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 seemingly shift and change from every vantage point.

  • someone finally brought this sort of an aesthetic down to a domestic and intimate scale in a thoroughly refined manner

    well done, except for that door off the garage – looks like a bitch to open/close

  • totally agree with dbkii for this bearable deconstructivist approach. About the door I had the same reserve, until I noticed it’s a sliding door, which make sense 🙂
    Otherwise, out of style consideration, another confirmation that our Japanese friends are the masters of micro space management. Kudos !

    thevzitor says:
  • I think I would feel constantly sea sick in this home. Too much slant in a small space for me. Even the photos make me feel a little queasy.
    To each their own I suppose!

  • Fantastic…
    I just need to get over my lack of appreciation of exposed concrete.
    Get over it.
