urban architecture office: FKI house

situated on a narrow site in tokyo, japan, the ‘FKI house’ by japanese firm urban architecture office finds itself amongst a residential district of ordinary wooden structures. the concrete volume contrasts and emerges from the mundane suburban backdrop, featuring a wood grain texture to respond to its surrounding context. the external form maintains the gable roof typical of the area, instead finishing the smooth surface with clean corners and edges. square oriel windows project from the façades, introducing natural daylight into the kitchen, living and dining areas on the upper level.

the main entry leads to a ground floor bedroom, enclosed with a rounded concrete wall. a poured-in-place stairway leads to the elevated common areas which use diverse floor heights to accommodate the activity of the inhabitants. strategically placed, it serves as a flexible surface for seating, resting and working for dwellers.

  • Damn that´s some rough architecture! But still cosy… I like you little concrete house.

  • Awsome project. Minimal interior.
    Good idea to put Eames plastic group with concrete :

  • Is it just me, or are these boxy Japanese concrete houses starting to feel old? It was cool the first 50 times, now it just feel very unimaginative. Furthermore i think a lot of them have really bad floor plans/use of space. Maybe it’s a cultural thing, but more often than not i get the feeling it’s a case of architects trying too hard to make the house “special” and “architectural”.

    I rather live in a Muji show room. At least there you can have stuff laying around without it ruining the “atmosphere”.

    Erik says:
  • I like the bathroom design and distribution I think is the best part of the house, the second floor loft looks unsafety. I realy don’t like the Idea of use the second floor “floor” as a dinning table.
    The concrete finish is poor and in my experience, concrete looks better with a smooth finish in case the arquitech decide to leave it without any other finish.
    Best regards

  • This house explains pretty well why there are building codes in the US. Looks like a death trap. Also not really sure I’d want somebody walking right in front of my dinner plate.

    Ari says:
  • I love the exterior, especially the ‘slides’ like you see on motorhomes. The flush glass makes them look perfect. The interior – solitary confinement..

    Jim C. says:
  • We had our apartment Red Tagged (condemned and torn down; California, US) in 2010. It was cement slabs with no wood; only steel support rods. That gray cement construction of this residence appears very similar to my unsafe building. Very interesting wall support around the bedroom and bathroom near the entrance but lack of support over the dining table would appear unfinished to me.

    Chris Jordan says:
  • I love this.
    CONGRATS to the architects!!!

    Diego says:
  • Awesum concept… awesum execution!

    ADG says:
  • Wow.. really interesting concepts. For me, personally I would add some colors….right now i feel like its just too dull. But overall the concept is great. Great post!
