akihisa hirata architecture office: coil

tucked within in a dense residential district of tokyo, the ‘coil’ residence by japanese practice akihisa hirata architecture office recedes into the context with a neutral, white exterior. following a continuous experiential sequence as some may consider life to be, the inhabitant’s experience a blurring of city and home, with a continuous spatial experience unveiled upon pulling into the garage. rooms are integrated into a singular corridor which gradually steps and rises throughout the interior.

three structural columns are evenly spaced within the footprint and span from the ground floor to the roof. the stairway then winds from the entry to the second floor. inhabitants move softly and organically between the interconnected spaces. derived from the complex order of a coil, the logical arrangement of the interior demonstrates the inherent order found even amongst living things.

the architect’s tangling exhibition is still on show through november 17th at the architectural association in london.

  • Seems all small housing proposals in Japan are variations on one theme: a winding stair to top with landings doubling as tiny rooms. No need for doors or privacy helps to service the program.

  • What a waste of precious space all those steps. Admitted it gives a nice spatiality but as a place to live it is utterly inefficient. I pitty the owners of this house who will have to pay off their loan over the next 20 years while in the meantime having to cope with the oddities of this house.

    knrf says:
  • using irregular layout as the advantage, choosing industrial furniture as the theme

    GQCNZ says:
  • I pity your pithy pragmatism

    dbkii says:
  • Excellent example of Japanese architecture flowing from the neighbourhood. Clean and small spaces are often well used by stakeholders. http://www.solidform.co.uk
