a renovation of a small parisian studio apartment focuses on a the relationship of different light qualities within the space, employing

binary sources of artificial illumination. french firm betillon / dorval-bory used an incisive, scientific approach to light within the

built form, using a range of indices to evaluate specific moments of color and spectral distribution. of particular use was the color

rendering index (CRI), a fundamental criteria for evaluating light that assesses the homogeneity of color rendering with respect to

spectral power distribution (SPD.) a low CRI range, for example, results in a loss of color range. given the technical considerations of

the project, lighting with alternately low or high CRI is composed according to the program– the kitchen and living room required

color distinguishing illumination, while the bed and shower merely require monochromatic light. the bipolarity of the light quality

helps shape the space, instead dictating use, circulation and paths of movement free of a plan and following the logic of composition

generated by light.

the architects strove to make interiors as neutral as possible, so as to allow the binary system to create a logical composition

the warm light is emitted from some low pressure sodium lamps with zero CRI

  • Don’t know much about the light thing, but the arrangement of volumes and voids and the double functional nature of the walk-on counter seems to be one of the clearest and most brilliant solutions ever for such a small room – very architectural. That is the key of the project, isn’t it? It is possibly very French to underline another aspect instead (i.e. light), like a sort of reality-denial…

    Bruno de Paris says:
  • i’m just curious…
    where do people take a dump in this apartment?

    Bronsom says:
  • Go back to the drawing board on this one. I don’t want people climbing next to where I prepare food.. Table with no view? really? Aesthetically a mess.
    Oh, and no toilet!

    nellie jackson says:
  • Look at the plan, theres a toilet opposite the kitchen units

    Daniel says:
  • Bronsom, you almost took the words right out of my mouth.
    I would have phrased it differently … but seriously, hats off for using the phrase taking a dump in a question about this minimalist Parisian architecture !!

    Hms says:
  • The toilet is shown on the floor plan ( isometric )

    Trish says:
  • Great project.
    Just the basics for an urban living with a lighting design bonus.

    Sidnei (São Paulo/Brasil) says:
  • Wonderful! But I see no toilet, neither cabinet/closet/storage place… I’d like to see the solution for these “problems” as well!

    Fernando says:
  • kinda liked the decayed room better

    pete says:
  • simply clean – excellent

    lothar f tindler says:
  • such whiny negativism

    I find it a “brilliant” set of solutions with regard to inhabiting a sliver of space

    and Trish, you are correct, there is a toilet – the whiners only want to find fault, not invest the time to really comprehend

    dbkii says:
  • Storage space for clothing?

    Pablo says:
  • An emotionless, antiseptic, intellectual space.
    It summarizes how architecture fails at times.

    Mike Jackson says:
  • why do brazilians typically write “(Brazil)” after their names on forums?
